Pseudotyped SARS-CoV-2 neutralizing antibody responses
Before booster vaccination, only 6.3%~11.8% of participants had a weak wild-type pseudovirus neutralizing antibody (PNAb) titer. Generation of PNAb against wild-type SARS-CoV-2 was significantly increased after booster vaccination in all groups (Pseudotyped SARS-CoV-2 neutralizing antibody responses. Similar kinetics were observed for the PNAb response against the Omicron BA.1 variant (The neutralization activity against new-emerging Omicron subvariants including BA.4/5, BQ.1.1, XBB and CH.1.1 was further evaluated (
