COVID-19 vaccine uptake and hesitancy among HIV-infected men who have sex with men in mainland China: a cross-sectional survey.

ABSTRACT

BACKGROUND: Men who have sex with men (MSM), a population bearing the greatest HIV burden in many countries, may also be vulnerable to COVID-19. COVID-19 vaccines are essential to containing the pandemic. However, vaccine hesitancy may compromise vaccine coverage. We aimed to understand the uptake of COVID-19 vaccine and factors associated with COVID-19 vaccine hesitancy among HIV-infected MSM in mainland China. METHODS: A cross-sectional online survey among HIV-infected MSM was conducted between 13 and 21 February 2021 in mainland China. Variables including demographics, mental health status, HIV characteristics, and knowledge of and attitudes toward COVID-19 pandemic and COVID-19 vaccine were collected. Chi-square tests and multivariable logistic regression were used to analyze factors associated with COVID-19 vaccine hesitancy. RESULTS: A total of 1295 participants were included. The median age was 29.3 years (interquartile range [IQR] 25.2-34.0 years). The uptake of COVID-19 vaccine was 8.7%. Two main reasons for receiving vaccines were "regarded vaccination as self-health protection" (67.3%) and "trust in domestic medical technology" (67.3%). Among participants who did not initiate vaccination, concern about side effects (46.4%) and disclosure of HIV infection (38.6%) were top two reasons, and 47.2% had higher vaccine hesitancy. Men who had with high antiretroviral therapy (ART) adherence (adjusted odds ratio [aOR] 0.53, 95% confidence interval [CI] 0.35-0.80), often (0.26, 0.17-0.40) or sometimes (0.46, 0.31-0.67) paid attention to information about the COVID-19 vaccine, preferred domestic vaccines (0.37, 0.24-0.59), thought the pandemic had moderate (0.58, 0.38-0.90) and moderately severe or severe impact (0.54, 0.38-0.78) on immunity, who were waiting for vaccination programs organized at workplace (0.60, 0.44-0.81) and who were unaware of where to get COVID-19 vaccine (0.61, 0.45-0.82) had lower degree of COVID-19 vaccine hesitancy. Men who were concerned about the efficacy (1.72, 1.16-2.54) and side effects (2.44, 1.78-3.35) had higher degree of COVID-19 vaccine hesitancy. CONCLUSION: COVID-19 vaccine uptake among HIV-infected MSM is still suboptimal. Understanding influencing factors of vaccine hesitancy among this group and making tailored measures to alleviate hesitancy would help improve the coverage of COVID-19 vaccination in this population.
