Brief Summary

The combined pertussis, diphtheria and tetanus vaccine, the first vaccine to be included in the Expanded Programme of Immunization(EPI) of World Health Organization(WHO), has played an important role in the prevention and control of these three infectious diseases. The (diphtheria,tetanus and acellular pertussis combined vaccine,DTaP) vaccine was successfully developed in China in 1993, and its safety and serological effects were confirmed by the observation of human safety, with mild vaccination reactions and good immunization effects.The (Diphtheria-tetanus-component acellular pertussis vaccine, DTcP) vaccine is suitable for immunization against pertussis, diphtheria and tetanus infections in people between 2 and 24 months of age.
