Abstract

Introduction: In 2015/2016, Canada’s largest provinces implemented publicly-funded human papillomavirus (HPV) vaccination programs for gay, bisexual, and other men who have sex with men (GBM) lesser than or equal to 26 years old. We sought to describe HPV vaccine uptake among GBM and determine barriers and facilitators to vaccine initiation with a focus on healthcare access and utilization. Methods: Engage is a cohort study among GBM aged 16 + years in three Canadian cities recruited from 2017 to 2019 via respondent driven sampling (RDS). Men completed a comprehensive questionnaire at baseline. By publicly-funded vaccine eligibility (lesser than or equal to 26 years old = eligible for vaccination, greater than or equal to 27 years old = ineligible), we described HPV vaccine uptake (initiation = 1 + dose, completion = 3 doses) and explored factors associated with vaccine initiation using Poisson regression. All analyses were weighted with the RDS-II Volz-Heckathorn estimator. Results: Across the three cities, 26–35% and 14–21% of men lesser than or equal to 26 years and 7–26% and 2–9% of men greater than or equal to 27 years initiated and completed HPV vaccination, respectively. Vaccine initiation was significantly associated with STI/HIV testing or visiting a HIV care specialist in the past six months (lesser than or equal to 26: prevalence ratio[PR] = 2.15, 95% confidence interval[CI] 1.06–4.36; greater than or equal to 27: PR = 2.73, 95%CI 1.14–6.51) and past hepatitis A or B vaccination (lesser than or equal to 26: PR = 2.88, 95%CI 1.64–5.05; greater than or equal to 27: PR = 2.03, 95%CI 1.07–3.86). Among men greater than or equal to 27 years old, vaccine initiation was also positively associated with accessing PrEP, living in Vancouver or Toronto, but negatively associated with identifying as Latin American and increasing age. Vaccine initiation was twice as likely among men greater than or equal to 27 years with private insurance versus no insurance. Conclusions: Sixty-five to 74% of men eligible for publicly-funded vaccine across the three cities remained unvaccinated against HPV by 2019. High vaccine cost may partly explain even lower uptake among men greater or less than 27 years old. Men seeking sexual health care were more likely to initiate vaccination; bundling vaccination with these services may help improve HPV vaccine uptake.
