Analyses of data collected in a large survey (sample size greater than 3000) of rubella antibody in South East England, finely stratified according to age, reveal age-dependent changes in the pattern of virus transmission. The rate or force of infection changes from low in the young children to high in the 5- to 15-year-olds and back to low again in the adult age classes (there is a 50% reduction between the 5- to 15-year-olds and the 20+-year-olds). Raised levels of immunity are recorded in the teenage and young adult female segments of the population as a consequence of the UK rubella immunization programme. Mean antibody concentrations show a decline with age and are, on average, lower in vaccinated females when compared with unvaccinated males of the same age. The interpretation of horizontal cross-sectional serological data and future research needs are discussed.
对英格兰东南部一项关于风疹抗体的大型调查(样本量超过3000)所收集的数据进行分析,该调查根据年龄进行了精细分层,结果显示病毒传播模式存在年龄依赖性变化。感染率或感染力从幼儿期的低水平变化到5至15岁儿童期的高水平,然后在成年年龄段又恢复到低水平(5至15岁儿童与20岁及以上成年人之间降低了50%)。由于英国的风疹免疫计划,在青少年和年轻成年女性人群中记录到了免疫力水平的提高。平均抗体浓度随年龄下降,与同年龄未接种疫苗的男性相比,接种疫苗的女性平均抗体浓度更低。文中还讨论了横向横断面血清学数据的解读以及未来的研究需求。
