Low measles seroprotection among adults with perinatally acquired HIV.

Adults with perinatally acquired HIV may be at unique risk for incomplete seroprotection from childhood measles vaccination. We examined measles seroresponse among a retrospective cohort of young adults with both perinatally- and nonperinatally acquired HIV. Among 322 individuals, only 14% had rubeola serology performed. Rubeola seroprotection was low (15.8%) among people with HIV (PWH) adults and was significantly lower than adults with nonperinatally acquired HIV (96%).
