与老年男性相比,老年女性对严重急性呼吸综合征冠状病毒2型(SARS-CoV-2)信使RNA疫苗产生了更大的体液反应。在6个时间点测定抗SARS-CoV-2疫苗株的A - D、抗刺突(S)免疫球蛋白(Ig) G (A)、S受体结合域(S- rbd) IgG (B)、血管紧张素转换酶2抑制抗体(ACE2iAbs) (C)和中和抗体(nAbs) (D):接种前(Pre;N = 82[48名女性,34名男性];未测定nAbs), <1个月后剂量1 (<1M_PD1;n = 23[12名女性,11名男性]),剂量2后<1个月(<1M_PD2;n = 69[41名女性,28名男性]),剂量2后3个月(3M_PD2;n = 82[48名女性,34名男性]),剂量2后6个月(6M_PD2;n = 80[47名女性,33名男性]),剂量3后11个月(1M_PD3;N = 60[34名女性,26名男性])。使用混合效应模型检验时间点之间的差异,并将研究时间点作为哑变量和对个体的随机截取。 Sex differences were tested using an expanded mixed-effects model that included a main effect for sex and an interaction term between sex and study time point. All point estimates are shown with error bars indicating the 95% confidence interval. Dashed lines show the limits of detection. E, All P values <.05 are reported; blank cells indicate a P value >.05, and crossed out cells indicate that the comparison is reported elsewhere in the table or not tested. F, Female-to-male ratios of geometric mean titers (GMTs) for each assay and each time point are shown, with the axis on a log2 scale. Abbreviations: AUC, area under the curve; F, female, M, male.
