In a randomized clinical trial, we compare early neutralizing antibody responses after boosting with bivalent SARS-CoV-2 mRNA vaccines based on either BA.1 or BA.4/BA.5 Omicron spike protein combined with wildtype spike. Responses against SARS-CoV-2 variants exhibited the greatest reduction in titers against currently circulating Omicron subvariants for both bivalent vaccines.
在一项随机临床试验中，我们比较了基于BA.1或BA.4/BA.5奥密克戎刺突蛋白与野生型刺突蛋白组合的二价SARS-CoV-2 mRNA疫苗加强接种后的早期中和抗体反应。两种二价疫苗针对SARS-CoV-2变体的反应在针对当前流行的奥密克戎亚变体的滴度上下降幅度最大。
