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



Benefits of Vaccination

COVID-19 vaccination is one of the most important tools to end the pandemic. Vaccines and boosters are safe and effective at preventing people from getting very sick or dying from COVID-19 and lowers the risk of developing "long COVID."  As with other vaccine-preventable diseases, you are protected best from COVID-19 when you stay up to date with the recommended vaccinations, including recommended boosters. 

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

Four COVID-19 vaccines are approved or authorized in the United States: 

  • Pfizer-BioNTech/Cominarty 
  • Moderna
  • Novavax 
  • Johnson & Johnson's Janseen 

These vaccines follow a specific vaccine schedule to ensure the highest level of protection. Learn more about vaccine dose timing by age

  • Primary Vaccine Series:  The Pfizer, Moderna, and Novavax vaccines require a second dose.  The Johnson & Johnson vaccine does not require a second dose but is more limited in its availability and eligibility criteria
  • Initial Monovalent Booster:  The initial booster was for people who completed their primary series. It did not specifically protect against omicron.
  • Updated Bivalent Booster:  The updated booster, also known as the “omicron booster” or “bivalent booster,” increases immunity against the original COVID-19 strain and the new omicron variants. It has been available since September 2022. Check your vaccination record and consider getting this updated booster it you have not already received it. 
  • 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.

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