HIV-positive children on highly active antiretroviral therapy (HAART) "may need to be revaccinated to maintain their immunity against preventable childhood diseases," according to researchers from the Johns Hopkins Bloomberg School of Public Health, HealthDay/BusinessWeek reports. After reviewing 38 studies, researchers found that children on HAART "had poorer responses to vaccines than do uninfected children," said study co-author William Moss. The children "respond well to revaccination," and the researchers recommend vaccination strategies be developed in regions with a high prevalence of HIV, the news service writes (9/8).
