The Marin County COVID-19 Status Update is published weekdays and as needed to share important news and resources related to the COVID-19 pandemic and to keep the local economy running. We remain here for you.  


Updated Guidance: Isolation and Quarantine 

Late last week, CDPH updated its guidance to align with the recommended isolation and quarantine timeframes from the Centers for Disease Control and Prevention (CDC). In this time of uncertainty due to Omicron, CDPH added additional testing recommendations to exit isolation and quarantine and improved masking measures to protect the health and well-being of all Californians.   

Isolation for COVID-19 Positive Individuals 

All individuals with COVID-19, regardless of vaccination status, should stay home for at least five days. Isolation can end after day five if symptoms are not present or resolving and if an antigen test collected on day five or later is negative. Masking is required when around others for 10 days from the date of positive test. 

Quarantine for Individuals Exposed to COVID-19 

Unvaccinated individuals who are exposed to COVID-19, and vaccinated people who are eligible for a booster but have not yet received a booster who are exposed to COVID-19, should stay home for at least five days and also get an antigen test on day five. They may leave their house after day 5 if no symptoms emerge and the results of the test taken on day 5 are negative. They should also wear a mask for 10 total days around others, notably while indoors. Without a test, people should quarantine for 10 days.  

Vaccinated individuals who have received their booster, or are not eligible for a booster, and are exposed to COVID-19 do not have to stay home but should wear a mask around others for 10 days and get tested on day five. Masks should especially be worn around others while indoors.  


FDA Greenlights Boosters for 12- to 15-Year-Olds 

The Food and Drug Administration (FDA) announced an amendment to its emergency use authorization for the Pfizer BioNTech COVID-19 vaccine today, paving the way for an expansion in age eligibility for booster shots. Details of the amendment are below:  

  • The age eligibility for a single dose COVID-19 booster shot from Pfizer now includes 12-to-15-year-olds. Previously, boosters for that brand were exclusive to recipients ages 16 and above.  
  • The timeframe of eligibility for a Pfizer booster shot has shortened from six months to five months after completion of an initial two-dose vaccination series.  
  • A third-party vaccination series has been authorized for children ages 5 through 11 who are considered immunocompromised.  

As we’ve seen with the rollout of pediatric vaccines, boosters for all three brands, and other amendments to emergency use authorizations, various steps remain before any of these updates are implemented in California. Proximately, the Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices (ACIP) will review Pfizer’s data and decide whether to approve of this amendment. Lastly, for the state of California to adopt these changes, the West States Scientific Safety Review Workgroup (WSSSRW) must conduct its own review after the FDA and CDC.
