Nuvaxovid COVID-19 vaccine is given as an injection into a muscle.

Nuvaxovid COVID-19 vaccine in people at least 12 years old is given:

  • unvaccinated individuals: a single dose of Nuvaxovid COVID-19 vaccine.
  • people who have already received a dose of any COVID-19 vaccine: a single dose of Nuvaxovid COVID-19 vaccine is given at least 2 months after the last dose of any COVID-19 vaccine.

The doctor or vaccination provider will determine whether an immunocompromised person needs additional doses.

Keep using infection control methods when you are in public or around others who may not have been vaccinated. This includes social distancing, hand-washing, using protective face covering, disinfecting surfaces you touch a lot, and not sharing personal items with others.

Receiving a COVID-19 vaccine will not cause you to test positive on a coronavirus test. However, once the body develops immunity to COVID-19, you could test positive on an antibody test (a test to detect immunity in the body from previous exposure to coronavirus).

It is not known how long this vaccine will protect you from infection with COVID-19. It also is not known how long immunity will last in a person who's been infected with and recovered from COVID-19. COVID-19 vaccine is still being studied and all of its risks are not yet known. Updated federal public health recommendations may be found at https://www.cdc.gov/covid/index.html
