目前还没有关于天花疫苗免疫反应中性别和种族差异的数据。我们招募了1076名18-40岁的健康成年人,他们接受了一剂美国许可的天花疫苗(Dryvax®)。使用基于表达重组β-gal的牛痘病毒的高通量中和测定法测定每个受试者血清中的牛痘中和抗体滴度。结果报告为抑制50%病毒活性的血清稀释度(ID 50)。所有受试者的中位ID 50为132.2(四分位距(IQR)= 78.8,205.6)。虽然未观察到人种和种族的显著差异,但女性的中和抗体滴度显著高于男性(158.5 [93.2,255.8] vs. 124.1 [75.2,185.9]; p < 0.0001)。正如预期的那样,接种疫苗后的时间也与我们受试者中中和抗体滴度的变化相关。这些数据表明,初次接种天花疫苗后的中和抗体滴度因性别而异。
There are no data currently available on gender and racial variation in smallpox vaccine immune responses. We recruited 1076 healthy adults 18–40 years old who received one dose of the US-licensed smallpox vaccine (Dryvax®). Vaccinia neutralizing antibody titers in each subject’s serum were determined using a high throughput neutralization assay based on a recombinant, β-gal expressing vaccinia virus. Results are reported as the serum dilution inhibiting 50% of virus activity (ID50). The median ID50 for all subjects was 132.2 (inter-quartile range (IQR) = 78.8, 205.6). While no significant differences were observed with race and ethnicity, females had significantly higher neutralizing antibody titers than males (158.5 [93.2, 255.8] vs. 124.1 [75.2, 185.9]; p < 0.0001). As expected, time since vaccination was also associated with variations in neutralizing antibody titers in our subjects. These data indicate that neutralizing antibody titers following primary smallpox vaccination vary by gender.
