Abstract
We report on the adverse reactions to the Bacillus Calmette-Guérin (BCG) vaccine in BCG-vaccinated children. We examined children exposed to the vertical transmission of human immunodeficiency virus (HIV) (n = 141), who participated in a prevention program of vertical transmission, and HIV-infected children (n = 66) in a setting endemic for HIV and tuberculosis (TB) in Brazil from August 2000 to February 2008. No cases of disseminated BCG disease occurred in either group of children. While no cases of regional BCG disease were noted in exposed/uninfected children, the rate of regional BCG disease in HIV-infected children was 4.5% (3/66); the three events occurred in <1-year-old children (3/17; 17.6%). One case was associated with severe immunodepression before highly active antiretroviral therapy (HAART). Two cases were manifestations of immune reconstitution inflammatory syndrome (IRIS). Among the HIV-infected children, the accrued benefits of potentially preventing severe TB outweighed the risks associated with the use of the BCG vaccine.
