COVID-19 Vaccine: What do you need to know?
COVID-19 vaccinations can help protect you from getting COVID-19. The vaccines help by making your body create an immune response without having to experience sickness and without being contagious to others. If the vaccine you get has two doses, it is very important to return for your second dose to get the best protection.
COVID-19 Vaccine Safety

- The U.S. vaccine safety system makes sure that all vaccines are as safe as possible. Learn how federal partners are working together to ensure the safety of COVID-19 vaccines.
