"COVID-19 can cause severe medical complications and lead to death in some people. There is no way to know how COVID-19 will affect you. If you get COVID-19, you could spread the disease to family, friends and others around you.
Getting a COVID-19 vaccine can help protect you by creating an antibody response in your body without your having to become sick with COVID-19.
A COVID-19 vaccine might prevent you from getting COVID-19. Or, if you get COVID-19, the vaccine might keep you from becoming seriously ill or from developing serious complications.
Getting vaccinated also might help protect people around you from COVID-19, particularly people at increased risk of severe illness from COVID-19."
