Humoral Immune Response after a Four-Site Intradermal Rabies Booster Vaccination in Previously Rabies Immunized HIV-Infected Adults

Methods We compared rabies neutralizing antibody titers (Nab) after a 4-site ID regimen with 0.1 mL of purified Vero cell rabies vaccine (PVRV) per inoculation site distributed at both deltoids and thighs vs. standard intramuscular injection using an ampule (0.5 mL) of PVRV at the deltoid on day 0 and 3 in thirty-eight previously rabies immunized HIV-participants who were on antiretroviral therapy and had CD4+ >= 200 cells/mL.
