Description and projection for the kinetics of antibody response to infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). With only a few months of experience to date, projections into years, although based on experience with other coronaviruses, must be regarded as speculative. Data on immunoglobulin A (IgA) responses are still emerging. Note: IgM = immunoglobulin M, IgG = immunoglobulin G.
