This study was conducted to determine immunity to diphtheria and tetanus in 232 inner-city women experiencing a recent birth. Forty-three (18.5 percent) of the women had levels of diphtheria antitoxin below the protective level (less than 0.01 unit/ml), whereas only 10 (4.3 percent) had insufficient levels of tetanus antitoxin. The percent of women susceptible increased with age, with 33 percent and 25 percent of women over the age of 30 years susceptible to diphtheria and tetanus, respectively.
本研究旨在确定232名近期分娩的市中心女性对白喉和破伤风的免疫力。43名(18.5%)女性的白喉抗毒素水平低于保护水平(低于0.01单位/毫升),而只有10名(4.3%)女性的破伤风抗毒素水平不足。易感染女性的比例随年龄增加,30岁以上的女性中分别有33%和25%易感染白喉和破伤风。
