  1. Anti-S Antibody levels targeting the spike protein of SARS-CoV-2. Anti-N Antibody levels targeting the nucleocapsid of SARS-CoV-2. 95% CI 95% confidence interval around the median value for each group, which are not calculated for groups with N≤10. Antibody levels are presented in WHO-standardized binding antibody units per milliliter (BAU/mL), log(10) scale
