Determinants of Potential HIV Vaccine Uptake Among Young Sexual Minoritized Men 17-24 Year Old

J Acquir Immune Defic Syndr. 2024 Dec 15;97(5):482-488. doi: 10.1097/QAI.0000000000003517.

Abstract

Background: Failures in prior rollout of HIV prevention efforts have widened disparities in HIV incidence by race/ethnicity among young sexual minoritized men (YSMM). We hypothesized greater perceptions of medical mistrust would be associated with lower willingness to get an HIV vaccine, mediating the relationship between race/ethnicity and willingness to accept a future HIV vaccine.

Methods: HIV-negative and unknown-status YSMM 17-24 years old (n = 229) recruited through social media and men-for-men networking apps completed online surveys from September 2021 to March 2022. Participants were asked about demographics, medical mistrust (health care-related sexual orientation stigma, health care-related race stigma, global medical mistrust, and trust in health care providers), and willingness to accept a future HIV vaccine.

Results: Vaccine willingness was highest among White YSMM (96.0%) and lower among Black (71.0%), Latino (83.6%), and multiracial or another race/ethnicity YSMM (80.0%). Even after accounting for medical mistrust constructs as mediators, compared with White participants, Black participants had lower odds of being willing to accept a future HIV vaccine. Participants with greater trust in health care providers had higher odds of willingness to accept a future HIV vaccine.

Discussion: Gaps in willingness to get an HIV vaccine are evident among YSMM by race/ethnicity, indicating potential further widening of disparities in HIV incidence when a vaccine becomes available without intervention.
