Hepatitis A vaccination in a racially and sexually diverse population of gay, bisexual, and other men who have sex with men: Findings from the QVax study

Background Previous studies found vaccination uptake of vaccine-preventable diseases (VPD) to be associated with race/ethnicity and medical mistrust among key populations, however, few studies examine Hepatitis A vaccination uptake. Methods This cross-sectional study used online survey data collected from NJ and NY residents identifying as lesbian, gay, bisexual, transgender, queer (LGBTQ+) from October 2021 through November 2022. Results This study used a subsample of 222 gay, bisexual, and other cisgender men, 66.7% White, with mean age 41.22 years (SD = 15.23), and 60% fully vaccinated for Hepatitis A. Overall, average group-based medical mistrust scores did not differ among non-vaccinated participants compared to fully or partially vaccinated participants. However, higher group-based medical mistrust scores were associated with non-White identifying participants, and were highest among Hispanic/Latinx (2.68, sd = 0.43) and Black non-Hispanic (2.58, sd = 0.50) participants (p < .001). Vaccination patterns did not differ among fear or vaccine confidence-based items. Conclusions Our results contribute to the limited knowledge of differences in Hepatitis A vaccination uptake among men who have sex with men, and support the need for targeted intervention programs that acknowledge the diverse population of LGBTQ + identifying individuals and their associated health behaviors.
