Abstract

We evaluated antibody levels after six months of the booster dose with BNT162B2 in previous recipients of CoronaVac and whether a subsequent SARS-COV-2 infection enhances the antibody response. The booster shot induced IgM and IgG antibodies against Spike protein. Infection after vaccination increased antibodies against protein N.
