Dengue is an important vector-borne disease occurring globally. Dengue virus (DENV) infection can result in a potentially life-threatening disease. To date, no DENV-specific antiviral treatment is available. Moreover, an equally effective pan-serotype dengue virus vaccine is not available. Recently, two DENV vaccines, Dengvaxia and Qdenga, were licensed for limited use. However, none of them have been approved in Bangladesh. DENV is transmitted by Aedes mosquitoes, and global warming caused by climate change favoring Aedes breeding plays an important role in increasing DENV infections in Bangladesh. Dengue is a serious public health concern in Bangladesh. In the year 2023, Bangladesh witnessed its largest dengue outbreak, with the highest number of dengue cases (n = 321,179) and dengue-related deaths (n = 1,705) in a single epidemic year. There is an increased risk of severe dengue in individuals with preexisting DENV-specific immunoglobulin G if the individuals become infected with different DENV serotypes. To date, vector control has remained the mainstay for controlling dengue; therefore, an immediate, strengthened, and effective vector control program is critical and should be regularly performed for controlling dengue outbreaks in Bangladesh. In addition, the use of DENV vaccine in curbing dengue epidemics in Bangladesh requires more consideration and judgment by the respective authority of Bangladesh. This review provides perspectives on the control and prevention of dengue outbreaks. We also discuss the challenges of DENV vaccine use to reduce dengue epidemics infection in Bangladesh.
Introduction
Dengue, the most prevalent and rapidly spreading mosquito-borne viral disease in humans, is caused by the arbovirus, dengue virus (DENV) (Guzman et al., 2010). DENV belongs to the family Flaviviridae and the genus Flavivirus (Kuhn et al., 2002). A recent study suggested enzootic transmission of DENV in different animals, including pigs, non-human primates, marsupials, horses, bovids, rodents, dogs, other small animals, and birds (Gwee et al., 2021). DENV spreads through infected mosquitoes biting during a blood meal and exists in both sylvatic and urban ecosystems (Vasilakis et al., 2010). Aedes aegypti and Aedes albopictus mosquitoes are the primary vectors for DENV transmission, and the spread of DENV depends on the human-mosquito-human cycle through the bites of infectious female mosquitoes (Lambrechts et al., 2010). Vertical transmission of DENV in mosquitoes between generations has been observed, but its significance is yet to be established (Mulyatno et al., 2012; Grunnill and Boots, 2016).
DENV has four serotypes, DENV-1, DENV-2, DENV-3, and DENV-4, which are genetically and antigenically different (Simmons et al., 2012). DENV can cause a spectrum of illnesses in humans, ranging from self-resolving dengue fever to severe dengue hemorrhagic fever (DHF), and life-threatening dengue shock syndrome (DSS) in a small proportion of individuals (Harris et al., 2000). According to the new dengue case classification provided by the World Health Organization (WHO), severe plasma leakage leading to DSS and fluid accumulation with respiratory distress, severe bleeding, and severe organ involvement, including the liver, heart, and central nervous system, are features of severe dengue fever (Srikiatkhachorn, 2009; Ajlan et al., 2019; Htun et al., 2021). According to the recent estimation, 58–96 million symptomatic DENV infections occur annually, with over 10 million cases requiring hospitalization (Bhatt et al., 2013; Shepard et al., 2016).
Severe dengue is prevalent in areas where more than one DENV serotype co-circulates (Lorono-Pino et al., 1999; Guzman et al., 2010; Aguas et al., 2019). Although infection with one serotype can provide long-term protection against that particular serotype, only short-term (less than 6 months) protection is induced against infection with other serotypes (Rothman, 2011; Reich et al., 2013; Katzelnick et al., 2017; Salje et al., 2018). DHF is more common in patients with secondary DENV infections than in those with primary infection (Rothman, 2011). It has been reported that individuals are exposed to the greatest risk for developing severe dengue when they experience two sequential DENV infections with two different DENV types separated in time by more than 18 months (Montoya et al., 2013; Anderson et al., 2014). The global burden of DENV infections is increasing, with more than 400 million cases reported annually (Kariyawasam et al., 2023). This increasing trend is thought to continue, fueled by urbanization along with high population densities, human mobility, and climate change (Yang et al., 2021). An increasing trend of dengue burden has also been observed in Bangladesh, and recently, the dengue outbreak has increased many folds, which could be impacted by ineffective vector-control strategies, climate change, high population densities, and unplanned rapid urbanization and construction (Gubler, 2011; Lindsay et al., 2017; Kolimenakis et al., 2021; Gibb et al., 2023; Kayesh et al., 2023a). Bangladesh lies at a frequent/continuous level based on the dengue risk level set by the Centers for Disease Control and Prevention (United States) (Centers for Disease Control and Prevention, 2023).
The first dengue outbreak was reported in 1964 in Bangladesh, the then East Pakistan, and the term Dacca fever was coined (Russell et al., 1966). In 2000 Bangladesh experienced a large epidemic for the first time that resulted in 5,551 dengue cases and 93 deaths (Yunus et al., 2001). The epidemic in 2000 was likely due to introduction of a DENV strain probably from Thailand (Sharmin et al., 2015). Since then dengue has become endemic in Bangladesh, and dengue cases show a close relationship with the seasonal variation (Mutsuddy et al., 2019; Kayesh et al., 2023a). Among 40,476 dengue cases reported from 2000 to 2017, less than 1% (0.94%) were found in the pre-monsoon season, whereas most cases were found in the monsoon (50%) and post-monsoon (49%) season, and the peak period of dengue cases lies between July to October (Mutsuddy et al., 2019). Another study analyzed the 2,334 dengue cases that were diagnosed in Dhaka at a private diagnostic facility during 2010–2014, and it was reported that 90% of cases occurred between June and November (Morales et al., 2016).
Usually, dengue infection is extremely low in Bangladesh during the winter season (November to January), and no dengue cases were reported in Bangladesh in January to May during 2010 and 2012. However, since 2013, dengue cases have been reported during the pre-monsoon season (January to April), suggesting a change in dengue occurrence (Akbar et al., 2023). Notably, during 2023 outbreak 566 dengue cases were reported in the month of January only, suggesting the changes in the dengue outbreak timing, which could be attributed to multiple factors, including climatic change, e.g., unusual episodes of rainfall and outbreaks in neighboring countries and increased traveling (Akbar et al., 2023; Mahmud et al., 2024). A serological survey by Dhar-Chowdhury et al. in 2012 observed a higher dengue seroprevalence (93%) in Dhaka city among individuals tested during post-monsoon (Dhar-Chowdhury et al., 2017). The household utilities and water management practices and destruction of mosquito breeding sites and participation in mass gatherings were identified as important factors affecting dengue exposure (Dhar-Chowdhury et al., 2017).
In 2019, Bangladesh experienced one of the largest dengue epidemics in history with 101,354 dengue cases and 164 dengue-related deaths (Kayesh et al., 2023a). However, Bangladesh has witnessed another devastating dengue outbreak that has surpassed all the previous records of dengue epidemics, with record-breaking numbers of dengue cases (n = 321,179) and dengue-related deaths (n = 1,705) in a single epidemic year of 2023 (Figure 1) (Directorate General of Health Services of Bangladesh, 2023). Dengue outbreaks during 2000 to 2018 were mainly centered in Dhaka, however since 2019 dengue outbreaks spread to different districts of Bangladesh (Kayesh et al., 2023a; Sharif et al., 2024). Notably, during 2023 outbreak more than 50% of dengue cases were from outside of Dhaka (Sharif et al., 2024). There is variation in dengue prevalence based on sex, where a higher male incidence, compared to female has been observed in Bangladesh (Salje et al., 2019; Prattay et al., 2022). Similarly, a higher male incidence (60%) was reported among dengue-infected people, compared to female incidence (40%) during 2023 outbreak (Ashraf et al., 2024; Sharif et al., 2024). A higher incidence in male could be explained by part due to exposure of working-age males to outdoor environments when Aedes aegypti mosquitoes remain active (Yew et al., 2009; Prasith et al., 2013). A similar pattern of higher male incidence has previously been reported in four Asian countries, including Lao People’s Democratic Republic, the Philippines, Singapore and Sri Lanka (Anker and Arima, 2011). A difference in dengue incidence among different age groups has been observed during 2023 outbreak, where highest dengue cases (28.7%) were found among people aged 19–29 years and the second highest incidence (28.1%) was in 0–18 years group, and the lowest incidence (0.3%) was in over 80 years of age group (Sharif et al., 2024). Notably, despite fewer female cases in 2023 outbreak, the death incidence was significantly higher among females, accounting for 57% of total deaths, and the highest case fatality rate (12%) was in children aged between 0 and 10, suggesting the influence of sex and age differences on morbidity and mortality (Ashraf et al., 2024; Sharif et al., 2024).
Figure 1. Number of reported dengue cases and dengue-related deaths per year in Bangladesh between 2008 and 2024. Data source: Directorate General of Health Services (DGHS) and the data for 2020 are limited due to COVID-19. The data for 2024 are partial (as of February 18, 2024).
Although dengue has no specific treatment, however, early diagnosis and proper clinical management can reduce the severity of dengue as well as dengue-related mortality (Tayal et al., 2023). Laboratory diagnosis of DENV infection can be done by direct detection of viral components (antigen detection) in the blood or indirect detection (antibody detection) by serological tests, depending on the day of illness (Kularatne and Dalugama, 2022). DENV infection causes alteration in vascular endothelial cell physiology and damage that lead to enhanced vascular permeability, inducing DSS (Basu and Chaturvedi, 2008). Early detection of the plasma leakage and appropriate fluid management remain key tool in management (Kularatne and Dalugama, 2022). Therefore, early clinical diagnosis and appropriate fluid treatment in plasma leakage may help in reducing DSS and dengue-related mortality (DENGUE Guidelines for diagnosis, treatment, prevention and control, 2009 WHO).
Although there are no panserotypes that are equally effective as dengue vaccines, there are two licensed dengue vaccines, Dengvaxia and Qdenga (Angelin et al., 2023; Thomas, 2023). However, no dengue vaccine has been approved for clinical use in Bangladesh. This new surge in dengue outbreaks indicates that the preventive measures taken to reduce dengue infections are insufficient, highlighting the necessity of further enhancement of preventive measures, as well as looking for new strategies, such as clinical trial of newly approved vaccine in Bangladeshi population for its suitability in Bangladesh. In this study, we provide a perspective on the enhancement of vector control programs and the things that need to be set/ensured before any approval of DENV vaccine use in Bangladesh.
Strategies to reduce increased dengue burden in Bangladesh
To date, there is no specific treatment for dengue, and control of the vector is the key to dengue control and prevention. Dengue transmission shows high sensitivity to climatic conditions, especially temperature, rainfall and relative humidity (Naish et al., 2014; Kamal et al., 2023). It has been reported that the abundance and transmission potential of Aedes aegypti are influenced by both temperature and precipitation, indicating Aedes as a climate-sensitive vector (Johansson et al., 2009). Temperature and rainfall patterns are also critical in influencing the seasonal patterns of dengue transmission, where both wet conditions and extreme drought can increase the risk of dengue with different delays (Lowe et al., 2021).
It has been reported that the number of hospitalizations was increased in Dhaka, Bangladesh by hydro climatological variability, including both high and low river levels (Hashizume et al., 2012). Hossain et al. showed that factors such as temperature, humidity, and windspeed are critical in the transmission cycles of dengue disease, however, dengue cases reduced with higher levels of rainfall (Hossain et al., 2023b). In another study, Rahman et al. showed that a one extra rainy day in a month can increase dengue cases by 6% in the succeeding month (Rahman et al., 2020), suggesting the importance of developing a climate-based warning system in Bangladesh for dengue control. An extended duration of the peak dengue outbreak was observed in Bangladesh, which could have been due to climate change.
In a recent study, it has been shown that temperature is the dominant factor that shape dengue’s distribution and dynamics in Vietnam, as the warming enhances the transmission risk of dengue (Gibb et al., 2023). A recent study showed meteorological factors, including dew point, relative humidity, and rainfall influence the daily dengue cases in Bangladesh (Islam et al., 2023). The urban infrastructure factors, including sanitation, water supply, long-term urban growth as well as human mobility could enhance dengue emergence (Gibb et al., 2023). Urbanization is an important element linking with ecological, entomological, and epidemiological parameters that associate with the distribution and density of Aedes mosquitoes and thus disease transmission (Kolimenakis et al., 2021). Therefore, the control of rapid and unplanned urban expansion in Bangladesh is critical for curbing dengue epidemic. The climate conditions in Bangladesh are getting increasingly favorable for dengue transmission (Karim et al., 2012). Therefore, enhanced vector control programs are key tool in curbing the increased dengue burden in Bangladesh.
Although global collaborative efforts are required to strengthen dengue preparedness, prevention, and control, a strategy based on dengue outbreaks in the respective countries is essential to successfully reduce the outbreak and its spread. As dengue is a vector (Aedes)-borne disease, the control of Aedes mosquitoes is critical. Notably, other vector-borne diseases transmitted by mosquitoes, such as malaria and leishmaniasis, have been successfully controlled by adopting proper vector control programs (Wilson et al., 2020), highlighting the significance of implementing an efficient dengue vector control program that would be equally effective in reducing the dengue burden. Singapore has achieved great success in controlling dengue using an effective vector control program (Sim et al., 2020).
An effective vector-based DENV prevention is key for reducing increased dengue burden, and controlling vector should adopt multiple approaches, including reduction of breeding source, destruction of larvae by larvicide treatment, mass trapping, sleeping under nets, and killing adults using adulticides, etc. (Saied et al., 2015; Barrera, 2022; Kayesh et al., 2023a). There are different vector control strategies under the physical, chemical, and biological methods, targeting Aedes aegypti and Aedes albopictus, and the combination of different strategies is more effective than any single approach (Lima et al., 2015).
Tires, plastic drums, plastic buckets, and coconut shells are the most prevalent container types used for Aedes habitats in Bangladesh, and these habitat management (physical control), including proper use, disposal, and recycling of the containers are important for reducing the breeding site as well as for reducing the risk of DENV transmission (Paul et al., 2018; Rahman et al., 2021). In addition, to prevent birth of Aedes larvae in stagnant water every resident should regularly clean any accumulated water on the roof of the house, in the courtyard, or even in flower tubs. Chemical control in the form of fogging and spraying insecticides targeting adult mosquitoes and larvae are routinely practiced in Dhaka City, Bangladesh, however, these approaches remain to be effective in mosquito control (Eisen et al., 2009; Kayesh et al., 2023a). Insecticides belonging to different classes of chemical such as pyrethroids, carbamates, organophosphates, and organochlorines are used for chemical control of mosquitoes (Van Den Berg et al., 2012). A recent study reported the resistance of mosquitoes to pyrethroid insecticides, where all Aedes aegypti populations showed a high-level resistance to permethrin at the diagnostic dose, with mortality ranging from 0 to 14.8% and a substantial resistance to higher (2×) doses of permethrin, with mortality ranging from 5.1 to 44.4% (Al-Amin et al., 2020). Although complete susceptibility to bendiocarb has been observed in all populations (Al-Amin et al., 2020), this insecticide is not registered in Bangladesh, suggesting the need for alternate use of insecticides for effective mosquito control. Mosquitoes are also susceptible to malathion and deltamethrin, which have already been registered in Brazil and can be used as effective alternatives (Dhaka Tribune, 2019; Al-Amin et al., 2020).
Biological control approaches such as Wolbachia-mediated control (Khadka et al., 2020; Utarini et al., 2021), use of larvivorous fish (Seng et al., 2008; Paiva et al., 2014; Weeratunga et al., 2017), larvicidal toxins produced by Bacillus thuringiensis subspecies israelensis (Bti) and Lysinibacillus sphaericus (Huang et al., 2017), use of sterile insect technique (Oliva et al., 2012) could be investigated in Bangladesh for preventing the spread of DENV infection. However, Bangladesh needs to find out the most effective approach in the country context, and strengthen the vector control program by considering the extended duration of the peak dengue outbreak period, following proper national planning, as well as the dengue outbreak monitoring system. Additionally, it is equally important to educate people about the spread of DENV and how its spread could be restricted or reduced. The use of long sleeves can help avoid mosquito biting, which will ultimately help reduce the spread by reducing the number of biting sites.
Although there is much improvement in the approaches for promising efforts against DENV infection (Troost and Smit, 2020; Kaptein et al., 2021), there is still a lack of antivirals or immune-based (monoclonal antibodies) prophylactics or therapeutics against DENV, highlighting the necessity of enhancement of developing new strategies for achieving effective ways for controlling dengue. In 2023 outbreak, Bangladesh experienced record-breaking deaths due to dengue, as well as a number of dengue cases, warranting immediate effective and enhanced dengue vector control programs in the context of Bangladesh. Until an effective dengue vaccine against all four serotypes is available and approved, the enhancement of vector control strategies with regular monitoring of insecticide efficacy against Aedes mosquitoes is critical for improving the present dengue situation in Bangladesh. The local government engineering department is leading vector control activities, such as the elimination of mosquito breeding sites, the use of larvicides, and adult mosquito control using different insecticides, such as temephos and deltamethrin. The respective authorities involved in mosquito control programs should take immediate measures to determine the reasons for the rise in dengue vectors as well as to take measures for mosquito control.
Dengue is considered underreported in Bangladesh, as the dengue outbreak record is only maintained by passive surveillance, where the data are obtained from health facilities and community (Sharmin et al., 2018; Husain et al., 2019; Mamun et al., 2019; Hossain et al., 2023a), highlighting the necessity of introducing laboratory-based active surveillance system covering all hospitals/clinics and diagnostic labs in Dhaka city and outside the Dhaka (Hossain et al., 2023a). Serologic surveillance is important to know seroprevalence of the dengue in humans, which help in knowing how widespread transmission has occurred (Dhar-Chowdhury et al., 2017). Notably, DENV is expanding to new areas in Bangladesh, therefore the introduction of genomic surveillance in mosquito vector could help in tracking the prevalent DENV that might be involved in the subsequent dengue epidemics (Heralde et al., 2023; Maduranga et al., 2023). As DENV-infected people remain the source of spreading infection upon biting by mosquitoes in infected people; therefore, the restriction of mosquito biting to DENV-infected people is important, which could be maintained using mosquito curtain and mosquito-repellant cream on body surface both in infected and uninfected people. To limit the spread of DENV infection, restricted movement of DENV-infected people should be strictly maintained; if required, legislation should be enacted.
Another important aspect is that standard diagnostics and hospitals should be ensured peripherally at upazila (sub-district) and district level to restrict the movement of DENV-infected patients from the periphery to the center, which will reduce the spread of the disease.
Different diagnostic approaches can be used for dengue detection, including NS1 based antigen testing, IgM/IgG antibody testing, and polymerase chain reaction (Kabir et al., 2021). However, dengue is commonly diagnosed by serological assays in dengue diagnostic facilities in Bangladesh targeting DENV NS1 antigen (at early case), or dengue-specific IgM (at early/primary infection) or IgG (after 10–12 days of primary infection or at secondary infection) (Kabir et al., 2021; Lima et al., 2022). Although IgM or IgG based testing is useful to routine diagnosis of dengue infection, however the issues of low specificity and sensitivity cannot be excluded (Kabir et al., 2021). A PCR-based detection of the DENV infection provides more accurate results, which can be practiced in dengue diagnostic facilities of Bangladesh.
Community awareness is critical in the control of dengue vectors, which can be ensured by source reduction, elimination of container habitats favorable for oviposition sites, and permitting the development of aquatic stages by tightly fitting lids or covers on containers, or by killing larval and pupal stages using insecticides. Thus, community awareness campaigns could play an important role in educating people and help reduce breeding places for mosquitoes. Legislation can also be enacted to enhance community involvement in destroying or reducing mosquito breeding sites. Notably, both Dhaka South City Corporation and Dhaka North City Corporation operated mobile courts in houses and establishments so that water did not accumulate on the roof of the house, courtyard, or flower tub, and imposed fines to keep the households clean and free of mosquito larvae (Dhaka Tribune, 2023a,b). An effective vector control program and a strengthened monitoring system are unavoidable for curbing the dengue burden in Bangladesh.
Recommended dengue vaccines for clinical use in individuals
A pan-serotype dengue vaccine with good efficacy has long been sought but is yet to be developed. As of February 18, 2024, there are two licensed, commercially available, live attenuated DENV vaccines sold under the brand names Dengvaxia and Qdenga. Dengvaxia, the first dengue vaccine, was developed by Sanofi Pasteur Co. and licensed in 2015 as a recombinant, live, attenuated, tetravalent dengue vaccine (CYD-TDV) (Hadinegoro et al., 2015). Yellow fever virus 17D was used as the backbone for Dengvaxia, and its prM/E RNA sequences were replaced with the corresponding prM/E RNA sequences of the DENV-1–4 serotypes (Guy et al., 2010). Dengvaxia was administered subcutaneously in three doses, and each dose was administered 6 months apart (at 0, 6, and 12 months) to obtain full protection. However, there are some limitations of Dengvaxia, such as age limitation (recommended for use in 9–45 years of age), recommendation for seropositive individuals (people who have been previously infected) only, increased risk of severe dengue development in seronegative participants, and serotype-dependent vaccine efficacy (Aguiar et al., 2016; Kayesh et al., 2021; Pintado Silva and Fernandez-Sesma, 2023), that have restrained its global use. Currently, Dengvaxia is available in only 20 countries (Pintado Silva and Fernandez-Sesma, 2023); however, it has not yet been approved in Bangladesh.
Takeda’s tetravalent dengue vaccine candidate (TAK-003) was based on live-attenuated DENV-2 (DEN2-PDK-53), which was originally designed and constructed by scientists at the Division of Vector-Borne Diseases of the US Centers for Disease Control and Prevention (CDC), providing a genetic backbone containing the three chimeric viruses containing the prM and E proteins of DENV-1, DENV-3, and DENV-4 (Huang et al., 2013; Osorio et al., 2016). TAK-003 was found to be effective against symptomatic dengue for over 3 years without any important safety risks in a 3-year long study of a population aged 4–16 years (n = 20,099) (Rivera et al., 2022). TAK-003 (Qdenga) is the second dengue vaccine to receive a license. It is a live, attenuated, and tetravalent dengue vaccine. The Qdenga vaccination course consisted of two injections administered 3 months apart. Phase III findings revealed that Qdenga appears encouraging compared to Dengvaxia (Thomas, 2023) (Table 1). Notably, in a phase III randomized controlled study, sequential or concomitant administration of the YF-17D vaccine and TAK-003 was found to be immunogenic and well tolerated, and non-inferiority of immune responses to YF-17D and TAK-003 was also observed for concomitant administration (Tricou et al., 2023).
Table 1. Comparison between two licensed dengue vaccines Dengvaxia and Qdenga.
The Qdenga vaccine is recommended for use in children aged 4–60 years and in seronegative individuals, which could prevent all four serotypes. Qdenga has already received approval for use in Europe, the United Kingdom, Brazil, Argentina, Indonesia, and Thailand by the European Medicines Agency for individuals over 4 years of age and as per national recommendations (Angelin et al., 2023). Brazil is going to be the first country to include Qdenga in its public health system (Alves, 2024). However, the use of Qdenga has not yet been approved in Bangladesh. The WHO approved Qdenga on October 2, 2023, for emergency use to prevent dengue (Dhaka Tribune, 2023c). However, the dengue working group of the CDC Advisory Committee on Immunization Practices (ACIP) revealed that Qdenga did not protect against all serotypes equally, where better protection was reported in seronegative recipients against DENV-1 and-2 infection but comparatively less protection against DENV-3 (Thomas, 2023). Therefore, none of the existing dengue vaccines is sufficient to provide complete protection in DENV-seronegative individuals against all four serotypes (Odio et al., 2023). An overall comparison between Dengvaxia and Qdenga is summarized in Table 1.
Dengue-related deaths have sharply increased in Bangladesh, which is presumed to be linked to the prevalence and coinfection of multiple serotypes-induced antibody-dependent enhancement (ADE) effects among DENV-infected people (Katzelnick et al., 2017). Moreover, the association of host genetic factors and the influence of increased genetic diversity of DENV on severe dengue development cannot be excluded. Therefore, it is time to consider all necessary measures aimed at curbing the spread of the disease and tackling severe dengue fever and dengue-related deaths, including the increased infrastructure facilities for vaccine research as well as suitability of the future dengue vaccine uses in Bangladesh. Dengvaxia is safe and effective in reducing dengue-related hospitalizations and severe dengue in seropositive individuals. Accordingly, the ACIP has recommended the use of the Dengvaxia vaccine in the United States for children aged 9–16 years living in dengue endemic areas and with evidence of earlier dengue infection (Paz-Bailey et al., 2021). Bangladesh is also a dengue-endemic country, and many dengue epidemics may render numerous DENV-positive individuals.
Notably, it has been reported that the Bangladesh government is also considering dengue vaccine introduction, for which the advice of the National Immunization Technical Advisory Group of Bangladesh has been sought on the use of dengue vaccine in the country (Dhaka Tribune, 2023c). However, many issues such as how the vaccine strategy will work, who will cover the vaccine and vaccination cost, which age group of people will be vaccinated, availability of vaccines, the ADE-related risk of vaccination in improperly screened people due to poor diagnostic facilities, etc. are required to be finalized before any introduction of DENV vaccine in Bangladesh. Importantly, a globally licensed and effective pan-serotype dengue vaccine is still required.
Dengue vaccines in different phases of clinical development
A pan-serotype-effective DENV vaccine that can inhibit DENV infection against all four serotypes in naïve individuals is yet to be developed. Moreover, ADE in the case of subprotective immunity poses a significant challenge to DENV vaccine development. However, many candidate vaccines are currently in different phases of development. TV003/TV005, a live attenuated tetravalent DENV vaccine candidate, was developed by the Laboratory of Infectious Diseases at the National Institutes of Health. Although TV003 and TV005 contain the same four monovalent components, they vary in dosing for serotype 2. TV005 contains a 10-fold higher dose of plaque-forming units to overcome the over attenuated serotype 2 component of TV003 (Whitehead, 2016). TV003/TV005 was found to be immunogenic and well tolerated, and administration of a single dose induced seroconversion to all four DENV serotypes in 74–92% (TV003) and 90% (TV005) of flavivirus-naive adults (Kirkpatrick et al., 2015; Whitehead et al., 2017). Notably, both the first and second doses (6 months apart) were well tolerated; however, no significant increase in antibody titers was observed after the booster dose (Kirkpatrick et al., 2015), suggesting that a single-dose regimen is likely to prevent DENV infection.
The vaccine candidates were licensed by several manufacturers for development, such as the Butantan Institute, Brazil, and a Phase II/III clinical trial was initiated (Durbin, 2020; Wilder-Smith, 2023). TV005 is the only single-dose tetravalent dengue vaccine, and a recent study evaluated the safety and immunogenicity of a single dose of TV005 across age groups in dengue-endemic Bangladesh (Walsh et al., 2023). To the best of our knowledge, this is the first study of a promising tetravalent dengue vaccine in dengue-endemic Bangladesh conducted by investigators from icddr,b, and the Larner College of Medicine at the University of Vermont (UVM). TV005 appears as good vaccine candidate and the efficacy, durability, and immune responses of this tetravalent dengue vaccine are ongoing worldwide (Walsh et al., 2023; Kallas et al., 2024). An ongoing phase 3, double-blind clinical trial in Brazil reported the overall 2 years vaccine efficacy findings in three different age groups (2–6 years, 7–17 years, and 18–59 years) (Kallas et al., 2024). It was observed that the highest efficacy was 90.0% (95% CI, 68.2–97.5) in the age group of 18–59 years, followed by 80.1% (95% CI, 66.0–88.4) in 2–6 years of age, and 77.8% (95% CI, 55.6–89.6) in 7–17 years of age group (Kallas et al., 2024). The vaccine efficacy differed between the serotypes, a higher efficacy (89.5, 95% CI, 78.7–95.0) was observed against DENV-1, compared to DENV-2 (69.6, 95% CI, 50.8–81.5), and DENV-3 and DENV-4 were undetected during the follow-up period (Kallas et al., 2024). Another recent study reported the findings of two randomized, controlled clinical trials of TV005, where this candidate vaccine was well tolerated and protected all vaccinated volunteers from viremia with DENV-2 or DENV-3 upon challenge with the rDEN2Δ30 or rDEN3Δ30 strain (Pierce et al., 2024), suggesting TV005 as a leading dengue vaccine candidate for further development.
In a Phase 1, double-blind, randomized, placebo-controlled study, a tetravalent live attenuated dengue vaccine manufactured in India was administered as a single subcutaneous injection in 60 healthy adults aged 18–45 years, revealing that the candidate vaccine was safe and well-tolerated (Gunale et al., 2023). The vaccine produced neutralizing antibodies and on day 57, the GMTs of neutralizing antibodies were between 66.76 (95% CI 36.63–121.69) to 293.84 (95% CI 192.25–449.11) for all four serotypes and was observed for 181 d. However, on day 181, the titers declined but were still much higher than the baseline (Gunale et al., 2023). Another Phase 1 study has been registered to evaluate the safety and immunogenicity of DENV-3 vaccination in a non-endemic population with the live attenuated recombinant DENV-3 monovalent dengue vaccine (rDEN3Δ30/31-7164) in seronegative, heterotypic (non-DENV-3), and more than one (polytypic) DENV serotype, which should provide information on immune responses upon primary, secondary, and tertiary exposure of DENV in naturally infected humans living in non-endemic areas (Trial registration: NCT05691530) (Odio et al., 2023).
The findings of a Phase 1 randomized clinical trial revealed that the V180 dengue vaccine candidate was safe and immunogenic in individuals who received the live attenuated tetravalent vaccine developed by the National Institute of Allergy and Infectious Diseases (Durbin et al., 2020). A phase I/II clinical trial of a cell culture-derived live-attenuated tetravalent dengue vaccine developed by Panacea Biotec Ltd. (PBL) was found to be safe and immunogenic in the Indian population (Mohanty et al., 2022). Although there was no statistically significant difference between the TDV and placebo groups in terms of AEs, the seroconversion rate in the TDV group was significantly higher (p < 0.001) than that in the placebo group (Mohanty et al., 2022). The seroconversion varied among vaccinated individuals against different serotypes, where among 92 individuals, 81.9% achieved seroconversion for DENV-1, 77.8% for DENV-2, 81.9% for DENV-3, and 79.2% for DENV-4 in TDV group (Mohanty et al., 2022).
Dengue vaccines in preclinical development
Owing to the unsatisfactory nature of the efficacy and safety profiles of available DENV vaccines, a safe and effective dengue vaccine is required (Seesen et al., 2023). A recent study reported that the chimeric DENV-2/4EDII replicates efficiently in vitro and in vivo. A single inoculation of DENV-2/4EDII induced type-specific neutralizing antibodies against both DENV-2 and DENV-4 in male macaques (Young et al., 2023). In the rhesus model, a recombinant subunit vaccine candidate, V180, composed of DENV-truncated envelope (E) proteins (DEN-80E) for all four DENV serotypes, was found to induce strong neutralization titers that inhibited viremia even 8–12 months after the last vaccination (Govindarajan et al., 2015). In a randomized, placebo-controlled, Phase I study, nine V180 formulations were evaluated, where all formulations were found to be well tolerated in flavivirus-naïve adults (Manoff et al., 2019), and all V180 formulations with ISCOMATRI adjuvant induced robust immunogenicity compared to aluminum-adjuvanted and unadjuvanted formulations (Manoff et al., 2019).
To develop an effective DENV vaccine, scientists continue their efforts in many ways, and a recent study developed a DENV mRNA vaccine candidate encoding the membrane and envelope proteins from DENV-1 encapsulated in lipid nanoparticles (prM/E mRNA-LNP), which elicited robust antiviral immune responses with high levels of neutralizing antibody titers and antiviral CD4+ and CD8+ T cell responses in a mouse model (Wollner et al., 2021). In addition, after prM/E mRNA-LNP vaccination, AG129 mice showed protection against a lethal DENV challenge (Wollner et al., 2021), suggesting its efficacy for further development. In an in vitro study, another multitarget mRNA vaccine composed of DENV-1, DENV-2, DENV-3, DENV-4 envelope domain III (E-DIII), and non-structural protein 1 (NS1) coated with lipid nanoparticles induced a robust antiviral immune response and increased neutralizing antibody titers, inhibiting DENV infection in all serotypes without significant ADE (He et al., 2022).
Another study constructed three nucleotide-modified mRNA vaccine candidates for DENV-2, including prME-mRNA, E80-mRNA, and NS1-mRNA, providing complete protection against DENV-2 challenge in immunocompetent mice (Zhang et al., 2020). Vaccination with E80-mRNA alone or in combination with E80-mRNA and NS1-mRNA can induce high levels of neutralizing antibodies and antigen-specific T cell responses (Zhang et al., 2020). A recent study reported that a cyclic dinucleotide (CDN)-adjuvanted recombinant DENV NS1 vaccine induced serotype-specific and cross-reactive antibody and T cell responses in a mouse model (Espinosa et al., 2019). In addition, homotypic and heterotypic protection from DENV-2-induced morbidity and mortality has been observed (Espinosa et al., 2019). Another study reported that DENV-2 envelope domain III combined with TLR agonists could induce strong immunological signatures involving immune cell trafficking, interferons (IFNs), and pro-inflammatory and T-cell responses; however, it showed only partial protection against viral challenges (Bidet et al., 2019).
A DNA vaccine candidate consisting of the tandem envelope protein domain III (EDIII) of four dengue virus serotypes 1–4 and the DENV-2 NS1 protein-coding region has been reported to induce pan-serotype neutralizing antibodies and antigen-specific T cell responses in a mouse model (Sankaradoss et al., 2022). Moreover, it has been shown that the passive transfer of immune sera could protect AG129 mice against a virulent, non-mouse-adapted DENV-2 strain challenge (Sankaradoss et al., 2022), suggesting good efficacy of the vaccine and warrants for further development. Hou et al. showed that mice sequentially immunized with DNA vaccines encoding prM and E for four DENV serotypes (DENV-1to DENV-4) induced higher levels of neutralizing antibodies against all four DENV serotypes and significantly higher levels of IFNγ-or tumor necrosis factor (TNF)α-expressing CD4+ and CD8+ T cells than tetravalent vaccination (Hou et al., 2020). Moreover, similar neutralizing Ab responses were observed against all four DENV serotypes after the second to fourth immunizations, suggesting that ADE may not be a serious issue (Hou et al., 2020); however, further studies are required to confirm the effect of sequential immunization on ADE of that DNA candidate vaccine.
C57BL/6 mice vaccinated with plasmids encoding the DENV-2 non-structural proteins NS1, NS3, and NS5 provided complete protection against a DENV-2 strain naturally capable of inducing lethal encephalitis in immunocompetent mouse strains. Moreover, protection is correlated with the cytokine profiles expressed by the spleen and brain-infiltrating mononuclear cells (Alves et al., 2020). A DNA vaccine candidate expressing the prM and E proteins of DENV-3 was reported to induce strong antigen-specific T-cell responses and robust neutralizing antibodies (Feng et al., 2020). In addition, vaccinated mice showed long-term immunity against three other serotypes (Feng et al., 2020). Another DNA vaccine candidate expressing the prM-E protein of DENV-4 provided effective protection against a lethal DENV-4 challenge in immunocompetent BALB/c mice (Sheng et al., 2019).
Minatev et al. reported the development of a dengue virus vaccine containing DIII domains of the envelope protein of four DENV serotypes as vaccine antigens and modified vaccinia virus Ankara as the viral vector (Mintaev et al., 2023). All vaccinated mice showed a humoral response against all four dengue virus serotypes and virus-neutralizing activity against DENV (Mintaev et al., 2023). Our team developed a dengue vaccine candidate using a recombinant attenuated DIs strain of vaccinia virus containing NS proteins (NS2-5) of DENV2c (rDIs-NS25), which was found to induce effective cellular immunity in mice. We also evaluated the protective effects of rDIs-NS25 against DENV-1–4 serotypes in AG129 (interferon-alpha and gamma receptor double-knockout mice) and A129 (interferon-alpha knockout mice)-DENV infection systems [ISV2023, Kyoko-Tsukiyama-Kohara et al.].
Challenges and prospects of clinical use of dengue virus vaccine in Bangladesh
Dengue is endemic to Bangladesh, and global warming and longer monsoon rains make it deadlier and one of the major public health concerns in Bangladesh (Walsh et al., 2023). The lack of an animal model that can comprehensively recapitulate human dengue infection remains a major challenge (Kayesh and Tsukiyama-Kohara, 2022), making it challenging to validate immune correlates of protection. Moreover, various risk factors, such as genetic background, sex, and other medical conditions including obesity, diabetes, and renal and cardiovascular diseases have been suggested to lead to the progression of severe dengue (Sangkaew et al., 2021). To date, no pan-serotype DENV vaccines have been approved. Moreover, the first licensed dengue vaccine, Dengvaxia, showed the inability to provide protection equally against all four serotypes; the least efficacy (42.3%) was reported in DENV-2 infection and the highest efficacy (77.4%) was against DENV-4 infection (Sabchareon et al., 2012). A 50.3% efficacy against DENV-1 and a 74.0% efficacy against DENV-3 infection was elicited by Dengvaxia (Sabchareon et al., 2012).
Managing a dengue outbreak in a tropical country, such as Bangladesh, is challenging, as favorable temperatures for mosquito breeding prevail almost year-round (Kayesh et al., 2023a). Moreover, Bangladesh is surrounded by two highly dengue endemic countries, including India and Myanmar that can cause increased viral transportation and transmission as well into Bangladesh (World Health Organization, 2023b). A recent study about dengue prevalence in Dhaka city reported the highest incidence of dengue in places with high ground temperature and lesser vegetation (Kamal et al., 2023). It has been reported that climatological circumstances such as higher temperatures, relative humidity, and precipitation can influence faster dengue transmission (Kamal et al., 2023). Another recent study also highlighted the increased local temperature and changes in rainfall seasonality contributing to increased dengue cases in Bangladesh (Hasan et al., 2024). In addition, air pollution may play an extra role in spreading dengue transmission (Lu et al., 2023) in Bangladesh. Moreover, the cross-reactivity of flaviviruses may lead to false diagnoses in clinical settings, resulting in delays in proper intervention and management. Therefore, accurate diagnosis with high specificity and sensitivity is essential to support the prompt and correct diagnosis of DENV infection (Kok et al., 2023). The genetic diversity of both DENV and its hosts poses another challenge in the use of the DENV vaccine; therefore, before introducing the vaccine, large efficacy trials demonstrating benefits across diverse populations in Bangladesh and clinical endpoints are warranted (Thomas, 2023). Because of ADE, each DENV serotype must be considered individually during vaccine development (Pintado Silva and Fernandez-Sesma, 2023). In Asia, DENV infection in children aged below 15 poses a higher risk of severe dengue development than in adults (Martina et al., 2009), and Qdenga use in children is supposed to reduce DENV infection as well as dengue-related severity. Therefore, the Bangladeshi government may consider Qdenga’s introduction as a new tool to mitigate dengue in countries like Bangladesh with a high disease burden (Wilder-Smith, 2024). However, according to one of the highest officials of the DGHS, the government of Bangladesh will follow a watch-and-see approach for any approval of Qdenga based on the efficacy of the vaccine in other markets.
Although severe DENV infections are not always associated with ADE and are preceded by infection with a heterologous serotype or increased viral load, many studies have demonstrated the role of ADE in DENV pathogenesis (Vaughn et al., 2000; Libraty et al., 2002; Wang et al., 2006; Simmons et al., 2007; Thomas et al., 2008; Teo et al., 2021, 2023b; Sawant et al., 2023). Similarly, the possibility of ADE exerted by the DENV vaccine could not be completely excluded. Therefore, before introducing a vaccine, it is critical to ensure the absence of ADE in vaccinated individuals. If there are any reports of vaccine-induced ADE effects on DENV infection, the vaccine must be stopped for use, and the DENV vaccine should only be recommended if there is no ADE in vaccinated individuals. However, a recent study in Mexico reported that individuals with at least two previous infections showed a comparatively lower risk of new infections than those in the seronegative group, suggesting the role of cross-immunity in protection (Amaya-Larios et al., 2020).
Although four DENV serotypes have been reported in Bangladesh, information on their evolution and genetic diversity remains limited (Suzuki et al., 2019). During 2000 and 2001 dengue outbreak in Bangladesh, DENV-3 was found as the most prevalent serotype, and that DENV-3 serotype was most closely related to DENV-3 emerged from neighboring Thailand and Myanmar but it was distinct from those from India and Sri Lanka (Podder et al., 2006). However, after that DENV-1 and DENV-2 were the predominant serotypes until 2016 (Figure 1) (Muraduzzaman et al., 2018; Ahsan et al., 2021). DENV-2 was the predominant serotype in 2017 and 2018 outbreak (Figure 1), which contained two distinct lineages of the DENV-2 Cosmopolitan genotype, and DENV-3 genotype I was found instead of DENV-3 genotype II, which was predominant during 2000 outbreak, indicating increased genetic diversity of DENV in Bangladesh (Suzuki et al., 2019; Rahim et al., 2023). DENV-3 genotype I was first detected in Bangladesh in 2017 (Rahim et al., 2023). Since 2019, DENV-3 has been the predominant serotype of dengue outbreak in Bangladesh (Figure 1) (Shirin et al., 2019; Rahim et al., 2021; World Health Organization, 2023a; Nafisa et al., 2024). In the 2023 outbreak, Bangladesh witnessed the highest number of dengue-related deaths (n = 1705) in a single epidemic year since the first recorded epidemic in 2000 (Directorate General of Health Services of Bangladesh, 2023). DENV-2, which is reported to be highly associated with severe form of dengue (Fried et al., 2010; Vicente et al., 2016), was identified as one of the predominant serotypes in the 2023 outbreak in Bangladesh (Figure 1) (World Health Organization, 2023a). Knowing which DENVs are circulating is important, however, there are limited information on the prevalent DENV serotypes in different outbreaks, suggesting a major gaps in surveillance system and early warning system (Haider et al., 2023); therefore, an adequate investigation of epidemiological research should be ascertained during any dengue outbreak, which could be helpful in predicting the dengue severity related to DENV serotypes and should help in early management in any future outbreak.
Dengue case fatality rates in Bangladesh from 2008 to 2024 (partial) are summarized in Table 2. There was a lack of dengue-related death from 2008 to 2018, which could be rendered by a lack of proper information/surveillance rather than the absence of dengue-related death. The case fatality rate (CFR) due to DENV infection has increased since dengue-related deaths were first recorded in 2019 (Table 2). The CFR for DENV infection in the 2019 outbreak was 0.16%, which is on the gradual increase, and more than three times higher (0.53%) in the 2023 outbreak and in the beginning of 2024, it appears 1.25% (as of 18 February, 2024) (Table 2), indicating a more severe recent dengue burden in Bangladesh. We cannot exclude the possibility of facing a more dangerous dengue situation in upcoming years if an effective vector control program is not implemented properly and in a timely manner. Moreover, the presence of DENV-4 as a predominant serotype may further worsen the future dengue epidemic in Bangladesh (Katzelnick et al., 2017; Kayesh et al., 2023a). Although Dengvaxia might be helpful in reducing the predicted death caused by DENV-4 infection, as Dengvaxia is highly effective against DENV-4, however, as Dengvaxia is recommended for seropositive individuals, avoiding the risk of vaccination in infection-naive individuals and ensuring the availability of a reliable DENV diagnostic tool in Bangladesh might appear to be a big challenge to overcome.

Future prospects
DENV has a unique and complex immunopathology that complicates dengue vaccine development. Moreover, the lack of suitable small animal models for immunopathogenesis studies and the absence of suitable markers of protective immunity are the major challenges in vaccine development that must be addressed (Ghosh and Dar, 2015; Kayesh et al., 2017). A large proportion of infected susceptible cells are infected with ADE, which can increase viremia and immunopathology (Wegman et al., 2023). An adequately reliable diagnostic tool with the desired sensitivity of 95% and specificity of 98% is essential for pre-vaccination screening to avoid any insufficient specificity and sensitivity in DENV detection, particularly in the detection of a previous monotypic dengue infection (Daag et al., 2021).
Sub-neutralizing or cross-reactive non-neutralizing antiviral antibodies remain a significant challenge in dengue vaccine development; therefore, it is important to develop an equally effective pan-serotype DENV vaccine lacking any ADE effect. TLR agonists can be investigated as dengue vaccine adjuvants to enhance the efficacy of dengue vaccines (Kayesh et al., 2023b). Wegman et al. demonstrated an association between DENV-reactive IgG and ADE in Fc gamma receptor-positive K562 cells. They further showed that IgA was not associated with ADE; rather, it effectively inhibited IgG-induced ADE activity (Wegman et al., 2021). Therefore, avoiding dengue vaccine-induced ADE is critical. Several studies (Goncalvez et al., 2007; Wang et al., 2017; Bournazos et al., 2020; Wegman et al., 2023; Teo et al., 2023a) have demonstrated the involvement of IgG in inducing ADE in DENV infection; therefore, the development of vaccines inducing DENV-specific cellular immunity to prevent DENV could provide a new platform for vaccine studies (ISV2023, Kyoko-Tsukiyama-Kohara et al.). As both the licensed DENV vaccines showed variable efficacy against different DENV serotypes and showed some limitations (Table 1), the ongoing efforts of different DENV vaccine development should be enhanced to have more suitable and effective vaccine candidate to battle DENV infection.
Conclusion
Dengue is a significant threat to public health in Bangladesh. The dengue outbreak in 2023 crossed all previous records, causing the highest number of dengue cases (n = 321,179) and dengue-related deaths (n = 1,705), which is alarming. Insufficient and ineffective vector control programs may have enhanced the current dengue outbreaks. Therefore, an effective vector control program using the most effective insecticide needs to be established by the government and respective institutions as the top most priority for preventing DENV infection. The presence of multiple serotypes in Bangladesh remains a major threat to ADE-mediated dengue severity and the presence of DENV-2 as predominat serotype in 2023 outbreak may contribute increased dengue-related deaths. As the use of Qdenga in seronegative individuals and Dengvaxia in seropositive individuals seems promising, vaccines could be considered an important tool in reducing DENV infection-induced casualties in future dengue outbreaks in Bangladesh. However, before introducing vaccines in Bangladesh, nationwide mass trials with these vaccines among Bangladeshi people should be conducted. Moreover, the issues like the vaccine strategy, vaccine supply, vaccine cost, vaccinates age group, and ADE-related to vaccination should be taken into consideration for taking final judgment of vaccine use in controlling dengue epidemics. Finally, the government should follow the WHO guidelines and suggestions from experts in the country before taking the final step in introducing the dengue vaccine in Bangladesh.
