Routine vaccination and vaccine-preventable infections in children born to human immunodeficiency virus-infected mothers. European Collaborative Study.

Information on vaccinations and vaccine-preventable infections collected in a prospective study of children born to human immunodeficiency virus (HIV)-infected mothers was analysed for reports of adverse reactions and to estimate the clinical efficacy of vaccines. No vaccinated, HIV-infected child developed measles (56 child-years' follow-up), mumps (33), rubella (33) or pertussis (239), and only one adverse reaction - to Bacillus Calmette-Guerin (BCG) - was reported. These findings provide limited evidence of the safety and efficacy of routine vaccination of HIV-infected children.
