Background: Although pre-exposure prophylaxis (PrEP) is highly effective in preventing HIV, PrEP uptake remains limited. Vietnam introduced PrEP in 2017 and scaled up from 2019. Private sector engagement (PSE) in PrEP service delivery is a scaling-up strategy. We assessed the effectiveness of this approach to inform ongoing efforts to accelerate ending AIDS by 2030.We implemented a process evaluation with longitudinal design using retrospective programmatic data collected and uploaded onto a secure online system (HMED) from 23 public and 17 private PrEP clinics in Hanoi, Ho Chi Minh City (HCMC), and Dong Nai. We measured the effectiveness of PrEP service delivery by PrEP initiation/reinitiation, uptake, persistence, discontinuation, and HIV seroconversion. We used the Kaplan-Meier time-to-event approach to estimate PrEP persistence and mixed-effects logistic regression analysis to assess factors associated with the PrEP persistence.Results: From October 2017 to September 2023, we started PrEP for 29,944 individuals, of which private clinics accounted for four times higher initiations than public clinics (79.3% vs. 20.7%, respectively). The median persistence of PrEP users at private clinics was significantly longer than that at public clinics (268 vs. 148, respectively). Mixed-effects logistic regression analysis results indicated a significant association between PrEP persistence for at least three months and initiating PrEP at private clinics (adjusted odds ratio [aOR] = 4.28; 95% confidence interval [CI]: 2.96-6.19), opting for TelePrEP (aOR = 3.42; 95%CI: 2.12-5.53), or being a client at 20 years and older (aOR = 1.86; 95%CI: 1.62-2.13). HIV seroconversion was significantly lower among PrEP users at private clinics compared to public clinics (0.03 vs. 0.13 per 100 person-years, respectively; p<0.01).Private sector PrEP service delivery is an effective approach to scaling up PrEP.Private-sector service providers play a pivotal role in increasing PrEP uptake and coverage and achieving HIV prevention goals.
