A coronavirus disease 2019 (COVID-19) vaccine can help you develop immunity to SARS-CoV-2, the virus that causes COVID-19, without getting ill. But how exactly do the different types of COVID-19 vaccines work?
Vaccines prompt an immune response so that your body remembers how to fight a virus in the future. Some vaccines use a whole virus to cause your immune system to respond. Other vaccines use parts of the virus or genetic material that provides instructions for making specific proteins like those in the virus.
Many COVID-19 vaccines involve a spikelike structure on the surface of the COVID-19 virus called an S protein. The S protein helps the virus get inside your cells and start an infection.
Manufacturers around the world are working on different types of vaccines. The main types of COVID-19 vaccines currently available in the U.S. or in large-scale clinical trials include:
In the U.S., the U.S. Food and Drug Administration has given emergency use authorization to the Pfizer-BioNtech and Moderna COVID-19 vaccines. More types of vaccines are expected to be authorized for use in the coming months.
A COVID-19 vaccine might prevent you from getting COVID-19 or from becoming seriously ill or dying due to COVID-19. Consult your local health department for the latest information on how and when you can receive a vaccine.
