What Do We Know About T Cells and COVID-19 Immunity? | SciShow News

The video discusses the role of T cells in immunity, particularly in relation to COVID-19. It addresses misconceptions about herd immunity and T cell immunity, explaining that while T cells can mount an immune response, it doesn't necessarily mean immunity from the disease. The video explores cross reactivity, where T cells trained to respond to one virus may react to similar viruses, and highlights research findings on T cell responses in different populations. It emphasizes the need for further research and continued precautions against COVID-19.
