COVID-19 vaccination of the healthcare workers (HCWs) is a key priority in the fight against the SARS-CoV-2 pandemic. India launched its COVID-19 vaccination program in January 2021. We aimed to understand the trends in willingness to receive COVID-19 vaccines and its associated factors among HCWs in India.
Using a repeated cross-sectional survey design, we collected information from HCWs in three critical time points: before (
Of the study participants, 43.7, 60.2, and 73.2% were willing to receive COVID-19 vaccines during the first, second and third rounds of surveys, respectively. In multivariable logistic regression analysis, participants who trusted the health care system were more likely to report willingness to receive a COVID-19 vaccine; medical trust emerged as a significant factor in all the three rounds of surveys (First survey—aOR: 2.24, 95% CI: 1.67–2.99; Second survey—aOR: 3.38, 95% CI: 2.64-4.33; Third survey—aOR: 2.54, 95% CI: 1.65–3.91). Having confidence in domestic vaccines (Second survey—aOR: 2.21, 95% CI: 1.61–3.02; Third survey—aOR: 2.05, 95% CI: 1.24–3.37); and high perceived risk of contracting COVID-19 (Second survey—aOR: 1.48, 95% CI: 1.13–1.93; Third survey—aOR: 2.02, 95% CI: 1.31–3.13) were found to be associated with willingness to receive vaccines. Among socio-demographic characteristics, being married (aOR: 1.71, 95% CI: 1.08–2.71) and having high socio-economic status (aOR: 3.01, 95% CI: 1.65–5.51) emerged as significant factors associated with willingness to receive COVID-19 vaccines in the third round of the surveys.
Willingness to receive COVID-19 vaccine increased with time, as the severity of the pandemic increased. To increase COVID-19 acceptance and coverage among HCWs, it is important to instill confidence in domestic vaccines and assist in accurate assessment of risk toward contracting COVID-19 infection.
