Differences in HIV vaccine acceptability between genders.
The development of safe and efficacious preventive HIV vaccines offers the best long-term hope of controlling the AIDS pandemic. Nevertheless, suboptimal uptake of safe and efficacious vaccines that already exist suggest that HIV vaccine acceptability cannot be assumed, particularly among communities most vulnerable to HIV. The present study aimed to identify barriers and motivators to future HIV vaccine acceptability among low socioeconomic, ethnically diverse men and women in Los Angeles County. Participants completed a cross-sectional survey assessing their attitudes and beliefs regarding future HIV vaccines. Hypothetical HIV vaccine scenarios were administered to determine HIV vaccine acceptability. Two-sided t-tests were performed, stratified by gender, to examine the association between vaccine acceptability and potential barriers and motivators. Barriers to HIV vaccine acceptability differed between men and women. For women, barriers to HIV vaccine acceptability were related to their intimate relationships (p<0.05), negative experiences with health care providers (p<0.05) and anticipated difficulties procuring insurance (p<0.01). Men were concerned that the vaccine would weaken the immune system (p<0.005) or would affect their HIV test results (p<0.05). Motivators for women included the ability to conceive a child without worrying about contracting HIV (p<0.10) and support from their spouse/significant other for being vaccinated (p<0.10). Motivators for men included feeling safer with sex partners (p<0.05) and social influence from friends to get vaccinated (p<0.005). Family support for HIV immunization was a motivator for both men and women (p<0.10). Gender-specific interventions may increase vaccine acceptability among men and women at elevated risk for HIV infection. Among women, interventions need to focus on addressing barriers due to gendered power dynamics in relationships and discrimination in health care. Among men, education that addresses fears and misconceptions about adverse effects of HIV vaccination on health and the importance of vaccination as one component of integrated HIV prevention may increase vaccine acceptability.
