Abstract
Background The World Health Organization recommends intradermal (ID) administration of rabies vaccine for preexposure prophylaxis. Methods In a randomized trial in adults assigned to 1 of 6 treatment groups (ID vs intramuscular [IM], 2 vs 3 doses, and controls), rabies neutralizing antibody titers were measured to 1 year postvaccination. Results ID vaccination produced acceptable antibody levels in all subjects (2- and 3-dose groups). At day 365, acceptable levels were 40% for IM and 50% for ID 2-dose schedule, and 70% for IM and 60% for ID 3-dose schedule. Conclusions ID rabies vaccination induces acceptable antibody titers at a fraction of the dose. Clinical Trials Registration NCT02374814.Keywords
