COVID-19 Vaccination Facts
- COVID-19 vaccines will not give you COVID-19. None of the COVID-19 vaccines currently in development use the live virus that causes COVID-19.
- COVID-19 vaccines will not cause you to test positive on COVID-19 viral tests. Vaccines won't cause you to test positive on viral tests, which are used to see if you have a current infection.
- People who have gotten sick with COVID-19 may still benefit from getting vaccinated. At this time, experts do not know how long until someone is protected from getting sick again after recovering from COVID-19. The immunity someone gains from having an infection (natural immunity) varies from person to person. Some early evidence suggest natural immunity may not last very long. Although there is no minimal interval between infection and vaccination, current evidence suggests reinfection is uncommon in the 90 days after initial infection, and thus persons with documented acute infection in the preceding 90 days may defer vaccination until the end of this period, if desired.
- Getting vaccinated can help prevent getting sick with COVID-19. There is no way to know how COVID-19 will affect you. If you get sick, you also may spread the disease to friends, family, and others around you while you are sick. COVID-19 vaccination helps protect you by creating an immune response without having to experience sickness.
- Receiving an mRNA vaccine will not alter your DNA. mRNA (messenger ribonucleic acid) can most easily be described as instructions for how to make a protein or even just a piece of a protein. mRNA is not able to alter or modify a person's genetic makeup (DNA).
