a, b GMC of SARS-CoV-2 RBD-specific IgG antibodies and GMT of pseudovirus-neutralizing antibodies to Omicron BA.4/5 in different age groups (18–59 years and 60–80 years) (a) and adverse reaction grade groups (b) on day 0, 14, 28, and 90 after booster vaccination with Ad5-nCoV (N = 100, 100, 99, 98) or inactivated SARS-CoV-2 vaccine (N = 99, 99, 98, 97). Data were shown as geometric mean ± 95% CI. Statistical significance was determined by two-tailed Student’s t-test and one-way ANOVA with Tukey’s multiple comparisons test. ns no significance; P < 0.05 was considered statistically significant and marked with red color. 95% CI 95% confidence interval, GMT geometric mean titer, GMC geometric mean concentration, GMFI geometric mean fold increase.
