Large-scale study of antibody titer decay following BNT162b2 mRNA vaccine or SARS-CoV-2 infection

Abstract

Large scale study display the kinetics of SARS-CoV-2 IgG antibodies present in individuals vaccinated with two doses of mRNA vaccine vs. unvaccinated patients who had recovered from the disease: initial levels of antibody are much higher in vaccinated patients, but decrease faster.
