A Three-Year Clinical Study On Immunogenicity, Safety, and Booster Response of Purified Chick Embryo Cell Rabies Vaccine Administered Intramuscularly or Intradermally to 12- to 18-Month-Old Thai Children, Concomitantly With Japanese Encephalitis Vaccine

After concomitant administration of purified chick embryo cell rabies vaccine and Japanese encephalitis vaccine to toddlers, adequate rabies and Japanese encephalitis virus neutralizing antibodies concentrations were demonstrated by day 49, 7 days after a booster at 1 year, and in the majorly at 3 years postvaccination. The inclusion of rabies vaccine in the expanded program on immunization should be considered in rabies endemic countries.
