The COVID-19 vaccine is a type of vaccine developed to provide immunity against the coronavirus SARS-CoV-2, which causes the disease COVID-19. These vaccines function by stimulating the immune system to recognize and fight the virus, thus helping to prevent infection and reduce the severity of illness if a person does contract the virus.
