The health and safety of Marin County residents is our top priority. A safe, effective COVID-19 vaccine is available to everyone.

COVID-19 vaccination is one of the most important tools to end the pandemic. Vaccines and boosters are highly effective at preventing people from getting very sick or dying from COVID-19 and lowers the risk of developing "long COVID." 


Benefits of Vaccination

People who have recovered from COVID-19 develop some immunity that weakens over time; the strongest immune response happens when a person has been vaccinated, boosted, and has recovered from infection. 

Common effects of the vaccine (which may include flu-like symptoms) are normal signs that the body is building protection and typically go away within a day. In contrast, COVID-19 infection commonly causes 1 – 2 weeks of symptoms and can lead to severe illness.  

Types of Vaccination

  • Primary Vaccine Series:  The Pfizer, Moderna, and Novavax vaccines require a second dose.  The Johnson & Johnson vaccine does not require a second dose.
  • Initial Booster:  The initial booster available prior to September 2022 was for those who completed the primary series and did not protect against omicron.
  • Updated Booster:  The updated booster also known as the “omicron booster” or “bivalent booster” will increase immunity against the original COVID-19 strain and the new Omicron variants.
  • Additional Doses:  Third or additional doses are available for those with weakened immune systems.


  • Primary Vaccine Series: anyone age 6 months & older
  • Updated Booster: anyone age 6 months and older who completed the primary series at least 2 months ago. Children age 6 months through 4 years who received the Pfizer vaccine may have different eligibility requirements.
  • Additional Doses: people with certain risk factors.

Children aged 6 months to 17 years must have permission from their parent or guardian to get vaccinated. Learn about vaccine dose timing by age.

If you are eligible, find a provider to get a COVID-19 vaccine.
