Extensive analysis of the antibody response, showed that SARS-CoV-2 induces virus-specific antibodies, mediated by all immunoglobulin isotypes including IgM, IgG, and IgA (Long et al., 2020); all IgG subclasses were produced by individuals with COVID-19, with IgG1 being the most dominant (Goh et al., 2021). This evidence concerns the gene CD79A and COVID-19.
