Intradermal simulated rabies postexposure prophylaxis using purified chick embryo rabies vaccine.

The antibody responses of 65 volunteers receiving an i.d. regimen (0.1 ml given at two different sites on days 0, 3, 7 and 0.1 ml given at one site on days 30 and 90) were compared with a control group of 35 volunteers receiving the standard i.m. regimen. By day 14, seroconversion was observed in all vaccinees in both groups. Geometric mean titers remained higher than 0.5 IU/ml throughout the study period. At the end of the observation period on day 365, antibodies persisted in all subjects. The multisite i.d. PCEC regimen has been proved as immunogenic as the standard i.m. regimen. Both regimens were well tolerated. Thus, it would be the effective and cheapest available rabies postexposure treatment using tissue culture vaccine.
