About the Vaccine

 

Last updated 11/22/2021

All people ages 5 and older are eligible to get vaccinated through Contra Costa Health Services (CCHS), even if they do not live or work in Contra Costa County

It is now recommended for many people to get a booster shot for maximum protection against COVID-19.

Vaccines are one of the most important tools to end the COVID-19 pandemic. A safe, effective, free COVID-19 vaccine is available to everyone ages 12 and older in California. The vaccine, paired with other daily health habits like wearing a mask, is our best protection against COVID-19

Why Should I Get Vaccinated?

Vaccination is our most powerful tool to end the pandemic. The vaccines give you strong protection from getting COVID-19 and even greater protection from serious illness, hospitalization and death from the virus. 

Together, the vaccine and other healthy habits like wearing a mask, offer the best protection from COVID-19.

What Can I Do After I’m Fully Vaccinated?

People are considered fully vaccinated 2 weeks after their second dose in a multi-dose series or 2 weeks after a single-dose vaccine. If it has been less than 2 weeks since your shot, or you still need to get your second dose, you are not fully protected. Keep taking all prevention steps until you are fully vaccinated.

Masking:

Contra Costa County requires masks in most indoor public places for all people, regardless of vaccination status. Public indoor settings include but are not limited to restaurants, retail stores, business offices, grocery stores, theaters, family entertainment centers, public transit, meeting rooms, and government facilities. Masks are not required in some indoor settings where everyone is fully vaccinated and other safety measures are followed. Click here for more details.

How Do the Vaccines Work?

The Pfizer and Moderna vaccines use messenger RNA (mRNA) to teach the body's cells to produce antibodies to protect you from COVID. Both of these vaccines require at least two doses. The Johnson & Johnson vaccine is what is called a “viral vector vaccine.” It uses a modified version of a different (and harmless) virus to deliver important instructions to our cells to fight infections. The Johnson & Johnson vaccine only requires one dose. The vaccines teach our bodies how to protect us against future infection with the virus that causes COVID-19.  

Are the Vaccines Safe?

Yes. Although the vaccines were developed in record time, they have gone through the same rigorous Food and Drug Administration (FDA) process as every other vaccine, meeting all safety standards. No steps were skipped. In fact, the state of California added another step by creating its own safety-review committee. Millions of people have been safely vaccinated around the world already.
