Overly robust immune response can lead to critical cases of COVID-19 – Innovation Origins

The antibodies bind to specific viral receptors and thereby prevent viruses from penetrating cells. At the same time, infected cells are tagged so that other protagonists in the immune system can then destroy the cell.
