Objective]To investigate the immune status of DPT in healthy population, evaluate the immune effect and provide scientific evidence to set immune strategy. Methods]446 persons were selected in Feixian in 2008,immune level of DTP was tested. Results]446 persons were tested. The immune successful rate,protective rate and GMT of pertussis were 68.39 % and 1 ： 306.56 ;the immune successful rate, protective rate and the antitoxin content of diphtheria were 77.13 and 0.11 IU/ml. Those of tetanus were 76.01% and 0.12 IU/ml. The immune successful rates of three antibodies under 15 were 76.53% ,84. 24% ,83. 42%. Conclusion]The result showed that the protective rate of DTP was much higher among people under 15,but the antibody level was much lower among the people over 15.
