Here, the authors characterize the antibody response from vaccinated (Pfizer BNT-162b2), infected and uninfected individuals against emerging variants of concern of SARS-CoV-2, finding reduced neutralization of a South African isolate. High IgG titers in the saliva of vaccinees suggest that transmission may be reduced.
