Serum from 995 subjects aged 6 months to 99 years was screened at a dilution of 1/8 for neutralising antibodies to poliovirus. Of these samples, 975 (98%) contained antibody to at least one serotype, and 763 (77%) contained antibody to all three, an improvement since previous studies. Children aged 8 to 15, however, had a low prevalence of antibody to poliovirus type 3, with only four (40%) of those aged 12 protected. This finding is possibly due to the waning of antibodies induced by the type 3 component of oral poliovirus vaccine and emphasises the continued importance of a booster dose of vaccine for those leaving school.
对995名年龄在6个月至99岁之间的受试者的血清进行了检测,以1/8的稀释度筛查针对脊髓灰质炎病毒的中和抗体。在这些样本中,975份(98%)含有针对至少一种血清型的抗体,763份(77%)含有针对所有三种血清型的抗体,这是自先前研究以来的一项进步。然而,8至15岁的儿童中,脊髓灰质炎3型抗体的流行率较低,12岁的儿童中只有4名(40%)受到保护。这一发现可能是由于口服脊髓灰质炎疫苗3型成分诱导的抗体逐渐减少,强调了对离校者进行疫苗加强剂量接种的持续重要性。
