Abstract:This prospective cohort study aimed to estimate the natural, vaccine-induced, and hybrid immunity to SARS-CoV-2, alongside the immunogenicity of the mRNA-1273 booster after the BNT162b2 primary series in healthcare workers in Colombia. IgG, IgA, and neutralizing antibodies were measured in 110 individuals with SARS-CoV-2 infection or a BNT162b2 primary series. Humoral responses and related factors were explored in a subgroup (n = 36) that received a BNT162b2 primary series followed by a mRNA-1273 booster (2BNT… Show more
