Failure of multiple-site intradermal postexposure rabies vaccination in patients with human immunodeficiency virus with low CD4+ T lymphocyte counts.

Human immunodeficiency virus (HIV)-infected patients with low CD4(+) T lymphocyte counts had a poor neutralizing antibody response to pre- and postexposure rabies vaccination. This study of HIV-infected patients with CD4(+) T lymphocyte counts < 200/microL indicated that patients had a poor response after 4-site intradermal vaccinations (4-4-4-0-2-2, doubling the intradermal doses of cell-culture rabies vaccine).
