In 1974 it was recommended that pertussis vaccine should continue to be offered in a triple vaccine together with diphtheria and tetanus vaccines. Further data on the prevalence of whooping cough and the incidence of adverse reactions have shown no reason to change this policy; the hazard of whooping cough remains greater than that of immunization.
1974年,有人建议百日咳疫苗应继续与白喉和破伤风疫苗一起作为三联疫苗提供。关于百日咳流行率和不良反应发生率的进一步数据表明,没有理由改变这一政策;百日咳的危害仍然大于免疫接种的危害。
