Update on Vaccination Recommendations for Adults with HIV.

PURPOSE OF REVIEW: Vaccination recommendations for people with HIV (PWH) differ from the general population given potential for diminished immune responses as well as increased risk for infection or more severe disease. This review highlights updated vaccine recommendations, summarizes available data informing use of vaccines, and identifies areas in need of additional study for adults with HIV.

RECENT FINDINGS: Vaccine recommendations differ for PWH in terms of timing, dosing, and need to check for serological response. New vaccines are available and recommended for PWH for prevention of invasive pneumococcal disease, respiratory syncytial virus (RSV), COVID-19, mpox, and hepatitis B virus (HBV). People with HIV experience persistent immune dysfunction, characterized by chronic immune activation and increased susceptibility to certain infections. To optimize potential of vaccines to reduce infection and infection-associated malignancies in PWH, strategies to improve vaccine responses and reduce vaccine hesitancy are necessary. While newer adjuvants show promise in enhancing immunogenicity, key questions remain regarding the durability of vaccine-induced protection and the ideal timing and necessity of booster doses for many vaccines.
