Correlates of neutralizing/SARS-CoV-2-S1-binding antibody response with adverse effects and immune kinetics in BNT162b2-vaccinated individuals.

ABSTRACT: While mRNA vaccines against SARS-CoV-2 are exceedingly effective in preventing symptomatic infection, their immune response features remain to be clarified. In the present prospective study, 225 healthy individuals in Japan, who received two BNT162b2 doses, were enrolled. Correlates of BNT162b2-elicited SARS-CoV-2-neutralizing activity (50% neutralization titer: NT₅₀; assessed using infectious virions) with various determinants were examined and the potency of sera against variants of concerns was determined. Significant rise in NT₅₀s was seen in sera on day 28 post-1st dose. A moderate inverse correlation was seen between NT₅₀s and ages, but no correlation seen between NT₅₀s and adverse effects. NT₅₀s and SARS-CoV-2-S1-binding-IgG lev
