Such details are important for filling in gaps in our understanding COVID-19 infections and tracking their spread in our communities. Levels of those IgG antibodies also served as an indicator for the presence of protective antibodies capable of neutralizing SARS-CoV-2 in the lab. The antibodies themselves are proteins, so giving them can sometimes cause something like an allergic reaction. The number and type of antibodies varied between people. Even after they reach the peak concentration, the body keeps producing antibodies and the memory B cells produced sometimes may gradually disappear after neutralizing the antigen organisms.
