On February 10th, the Centers for Disease Control (CDC) announced some recent changes to quarantine requirements for those who are fully vaccinated. This update comes at a perfect time as more people are getting vaccinated and as many are beginning to wonder what life will look like post-vaccine.
If you have been following the news, or if you have been recently vaccinated, you have most likely heard the recommendations: Vaccinated persons should continue to follow current guidance to protect themselves and others, including wearing a mask, staying at least 6 feet away from others, and avoiding crowds.
But why must those who have received both doses of vaccine continue to practice these safety precautions? Shouldn’t we be able to go back to normal once vaccines are more readily available?
Well…the science just isn’t there quite yet to tell us otherwise!
What we know—and don’t know just yet
We know that the currently approved COVID-19 vaccines are highly effective at preventing symptomatic COVID-19, meaning that those who have received a full vaccine series have protection against developing symptoms and are especially protected against severe illness related to COVID-19. The evidence also shows that symptomatic and pre-symptomatic transmission has a greater role in transmission that purely asymptomatic transmission.
While mRNA COVID-19 vaccines (like Pfizer and Moderna) have demonstrated high efficacy at preventing severe and symptomatic COVID-19, there is limited information on how effective the vaccines are at reducing transmission and how long protection lasts. The efficacy of the vaccines against emerging SARS-CoV-2 variants is also not yet known.
As we wait to learn more about how much vaccines are able to reduce transition, it is best to be cautious. Counties across Washington State have shown reductions in COVID-19 cases in the past several weeks, and it is best to keep doing what we know works best against the virus.
If you are like me though, you may be looking for a glimmer of hope for the coming months. The updated CDC quarantine guidelines is a promising example of the benefits that vaccinated individuals will begin to see.
Updated Guidance for Vaccinated Persons
The CDC states that vaccinated persons with an exposure to someone with suspected or confirmed COVID-19 are not required to quarantine if they meet all of the following criteria. Persons who do not meet all three of the below criteria should continue to follow current quarantine guidance after exposure to someone with suspected or confirmed COVID-19:
1. Are fully vaccinated (i.e. it has been longer than two weeks following receipt of the second dose in a two-dose series, or it has been longer than two weeks following receipt of one dose of a single-dose vaccine).
2. Have remained asymptomatic since the current COVID-19 exposure.
3. Are within three months following receipt of the last dose in the series (meaning that an individual is no more than three months out from their last vaccine dose).
Experts are currently gathering data about the duration of immunity to COVID-19 post-vaccination. At present, we have good data confidence to say that immunity lasts for 90 days (or three months). This may change as more data is gathered and analyzed.
Vaccinated healthcare personnel, patients, and residents in healthcare settings
If you are a healthcare worker, patient, or resident of a healthcare setting, these new updates will not apply to you. This exception is due to the unknown vaccine effectiveness in this population, the higher risk of severe disease and death, and challenges with social distancing in healthcare settings. These individuals must continue to follow current quarantine guidance.
Exposed and feeling sick. Now what?
Fully vaccinated persons who do not quarantine should still watch for symptoms of COVID-19 for 14 days following an exposure. If they experience symptoms, they should be clinically evaluated for COVID-19. In addition, vaccinated persons should continue to follow current guidance to protect themselves and others, including all other SARS-CoV-2 testing recommendations and requirements, and state, territorial, tribal, and local travel recommendations or requirements.

More to come
The CDC quarantine recommendations for vaccinated persons, including the criteria above, will be updated when more data becomes available and additional COVID-19 vaccines are authorized.
To find out if you are currently eligible for vaccine in Washington State, visit www.findyourphasewa.org. If eligible, people can register for an appointment at one of the many vaccine provider locations: https://www.doh.wa.gov/YouandYourFamily/Immunization/VaccineLocations. Please know that vaccine supply is still quite limited at this time, and it will take several months for all currently eligible individuals to receive vaccine.
