Humoral immune response with ChAdOx1 nCoV-19 (n = 133) and GEMCOVAC-OM (n = 271) assessed by PRNT 50 (a) and anti-spike IgG antibodies (b). The data are presented as geometric mean with 95% CI. LSGMR with 95% CI at day 29 and day 90 along with the P value was calculated using ANCOVA with baseline values as covariates. Change in titers from baseline to day 29 and day 90 was calculated by using a two-sided paired t-test or Wilcoxon signed-rank test based on normality. NS, not significant.
