Vaccine acceptability, uptake and completion amongst men who have sex with men: A systematic review and a theoretical framework


Due to an increased risk of sexually transmitted infections (STIs), gay, bisexual and other men who have sex with men (MSM) have been targeted to receive vaccinations against human papillomavirus, meningitis C and hepatitis A/B. Our research aimed to compare the levels of acceptability, initiation and completion for vaccines targeted at MSM and to identify associated factors. Four databases were explored in January 2020 to identify vaccination behaviours and associated factors among MSM. A meta-analysis was performed, and factors were synthesised to inform a theoretical framework. Seventy-eight studies, mostly from the USA, were included. The average vaccine acceptability was 63% (median=72%, range: 30%-97%), vaccine uptake was 45% (median=42%, range: 5%-100%) and vaccine completion was 47% (median=45%, range: 12%-89%). Specific demographic, behavioural and healthcare-related factors were identified, such as access to sexual networks and specialist sexual health services. Knowledge and psychological variables (i.e. risk perceptions, attitudes, vaccine-related beliefs) were correlated with acceptability, uptake and completion. Despite overall high levels of acceptability, uptake and completion were below targets outlined by cost-effectiveness modelling across all recommended vaccines. Addressing multiple levels of determinants outlined in our theoretical framework can guide interventions to increase vaccine completion among MSM.
