is coivd contain any antigens?
1 answer
Yes, COVID-19 (caused by the SARS-CoV-2 virus) contains antigens. Antigens are molecules that can induce an immune response in the body, and they are typically protein structures found on the surface of pathogens. In the case of COVID-19, the viral spike protein is considered the primary antigen. This protein allows the virus to attach to and enter human cells by binding to a receptor called ACE2. The spike protein is a main target for vaccine development as it generates an immune response and antibodies that can neutralize the virus.
