SARS-CoV-2-specific humoral response following vaccination with BBIBP-CorV in SARS-CoV-2 naïve individuals. (A) SARS-CoV-2 spike-specific IgG antibodies were measured 21 to 30 days after the first (T1) and second (T2) doses, and three months after dose 2 (T3). (B) IgG anti-spike antibody levels after dose 2 of BBIBP-CorV vaccine in subjects older and younger than 50 years. (C) anti-spike IgG antibody concentrations after the first and second doses of BBIBP-CorV vaccine in men and women. IgG anti-spike antibody concentrations are shown in International Units/mL (IU/mL). Geometric means with 95 % confidence intervals are shown. p values were determined by Unpaired t-test or Mann-Whitney test.
