Mucosal antibody responses to SARS-CoV-2 booster vaccination and breakthrough infection

Here, the investigators measured serum IgG, saliva IgG and saliva secretory IgA responses in individuals who experienced breakthrough infections and who received COVID-19 mRNA booster vaccinations.本研究中，研究者对既发生过突破性感染（breakthrough infections）、又接种了COVID-19 mRNA加强疫苗（COVID-19 mRNA booster vaccinations）的个体，检测了其血清免疫球蛋白G（serum IgG）、唾液免疫球蛋白G（saliva IgG）以及唾液分泌型免疫球蛋白A（saliva secretory IgA）的免疫应答水平。
