Obesity emerged as a risk factor for morbidity and mortality related to 2009 pandemic influenza A (H1N1) infection. However, few studies examine the immune responses to H1N1 vaccine among children and adults of various body mass indices (BMI). Pooling data from 3 trials of unadjuvanted split-virus H1N1 A/California/07/2009 influenza vaccines, we analyzed serologic responses of participants stratified by BMI grouping. A single vaccine dose produced higher hemagglutination inhibition antibody titers at day 21 in obese compared to nonobese adults, but there were no significant differences in responses to H1N1 vaccine among children or adults of various BMI following 2 doses.
肥胖已成为与2009年甲型H1N1大流行性流感感染相关的发病和死亡风险因素。然而,很少有研究考察不同体重指数(BMI)的儿童和成人对H1N1疫苗的免疫反应。我们汇总了3项关于无佐剂裂解病毒H1N1 A/加利福尼亚/07/2009流感疫苗试验的数据,分析了按BMI分组的参与者的血清学反应。与非肥胖成人相比,肥胖成人在第21天时单剂疫苗产生的血凝抑制抗体滴度更高,但2剂疫苗接种后,不同BMI的儿童或成人对H1N1疫苗的反应没有显著差异。
