Abstract

In the present study, Pušnik et al. investigated whether the XBB.1.5-adapted booster can overcome the persistent imprinting of SARS-CoV-2 immunity by wild-type based vaccines. The findings demonstrate increased plasma neutralization against the homologous variant following the booster vaccination. Formation of de novo humoral response against the mutated epitopes of XBB.1.5 variant's surface proteins was observed in 3/20 individuals. The booster vaccination had no significant effect on T-cell response.

XBB.1.5适应性加强免疫对SARS-CoV-2免疫印记的影响。
在本研究中,Pušnik 等人调查了 XBB.1.5 适应型加强型疫苗是否能克服野生型疫苗对 SARS-CoV-2 免疫力的持续印记。研究结果表明,接种加强型疫苗后,血浆对同源变体的中和作用增强。在 3/20 人中观察到了针对 XBB.1.5 变异体表面蛋白变异表位的新体液反应。加强接种对 T 细胞反应没有明显影响。
