Common Cold T-Cells Can Fight Covid: ICL Study

The video discusses the role of T cells, induced by previous common cold infections, in providing natural immunity against COVID-19. It highlights that some people exposed to COVID-19 do not get infected due to these T cells. The discussion extends to the development of vaccines, emphasizing the potential for a universal vaccine that targets internal virus proteins, offering protection against all variants. The video also clarifies that common cold immunity does not guarantee protection against COVID-19 and stresses the importance of vaccination.
