近年来对人群的免疫观察表明,在接种过吸附 DTP 的儿童中,百日咳发病率有所增加。这当然是由于儿童对 DTP 中的百日咳组分免疫应答弱的结果。作者认为菌苗免疫效果的决定因素之一是菌苗对接受者的非己性,而免疫应答弱的原因之一是人体与微生物之间有共同抗原。 In recent years, immunization of the population showed that the incidence of whooping cough increased in children who had been inoculated with DTP. This is of course due to the poor immune response in children to pertussis components in DTP. The author believes that one of the determinants of the vaccine’s immune effect is the non-identity of the bacterin to the recipient, and one of the reasons that the immune response is weak is that there is a common antigen between the human body and the microorganism.
