Neutralization failure against wild-type SARS-CoV-2 (WT) and omicron subvariants, and correlation of neutralization and antibody responses following XBB.1.5 vaccines. (a) Proportions of individuals lacking neutralization against the indicated SARS-CoV-2 variants before (pre) and two to four weeks after (post) vaccination. (b) Correlations of antibody and neutralizing responses targeting wild-type SARS-CoV-2 (WT) and omicron subvariants, two to four weeks after vaccination. Statistical analyses are based on Fisher’s exact tests (a) and Spearman’s rank correlations with 95% confident intervals (b).
