A study published by the journal Cell on January 12, 2021, found 'The adaptive immune system is important for control of most viral infections. The three fundamental components of the adaptive immune system are B cells (the source of antibodies), CD4+ T cells, and CD8+ T cells.'

'The armamentarium of B cells, CD4+ T cells, and CD8+ T cells have different roles in different viral infections, and in vaccines, and thus it is critical to directly study adaptive immunity to SARS-CoV-2 to understand COVID-19.'

'While more studies are needed, a picture has begun to emerge that reveals that CD4+ T cells, CD8+ T cells, and neutralizing antibodies all contribute to controlling of SARS-CoV-2, in both non-hospitalized and hospitalized cases of COVID-19.'

In 2020, the U.S. FDA issued emergency authorizations for various antibody treatments targeted against COVID-19.
