What if I'm exposed to COVID-19 after my vaccination? - Post Exposure Guidelines

CDC recommendations on masking for fully vaccinated people.

Note that State and Local guidance may be stronger than CDC guidance based on severity of disease spread in our area.

We’re still learning how vaccines will affect the spread of COVID-19. After you’ve been fully vaccinated against COVID-19, you should keep taking precautions in public places like wearing a mask, staying 6 feet apart from others, and avoiding crowds and poorly ventilated spaces until we know more.   

You may also need to follow quarantine/isolation 
protocols if exposed to a COVID-19 case or if you have symptoms of COVID-19.  Please work with public health contact tracers for guidance specific to your situation.

What it means to be Fully Vaccinated

People are considered fully vaccinated:

2 weeks AFTER their second dose in a 2-dose series, like the Pfizer or Moderna vaccines,
2 weeks AFTER a single-dose vaccine, like Johnson & Johnson’s Janssen vaccine

If it has been less than 2 weeks since your shot, or if you still need to get your second dose, you are not yet receiving all the protective benefits of the vaccine. We recommend all community member continue  prevention steps as we work towards community immunity.  This includes quarantining/isolating if you are sick or exposed to a person with COVID, especially if the exposure was before you reached fully vaccinated (2 weeks after the final dose).

What We Know and What We’re Still Learning

  • We know that COVID-19 vaccines are effective at preventing COVID-19 disease, especially severe illness and death.
    • We’re still learning how effective the vaccines are against variants of the virus that causes COVID-19.
    • Early data show the vaccines may work against some variants but could be less effective against others.
  • We know that other prevention steps help stop the spread of COVID-19, and that these steps are still important, even as vaccines are being distributed.
    • We’re still learning how well COVID-19 vaccines keep people from spreading the disease.
    • Early data show that the vaccines may help keep people from spreading COVID-19, but we are learning more as more people get vaccinated.
  • We’re still learning how long COVID-19 vaccines can protect people.
