Omicron Boosters Now Available at County-Run Vaccination Sites

Contra Costa Health Services (CCHS) has announced that, as of Friday, September 9, it is offering the new Omicron booster shots at its COVID vaccination sites.

Vaccinated people ages 12+ are eligible to receive Pfizer’s new Omicron booster and adults ages 18+ can get Moderna’s Omicron booster. These recently authorized “bivalent” booster shots are designed to protect against both the original coronavirus strain and the newer Omicron variants now dominant in the United States.

To be eligible, people must have completed their primary vaccination series or gotten their last booster shot at least two months before getting the Omicron booster.

People can schedule a booster appointment at County-run vaccination sites online at or by calling CCHS at 833-829-2626. County vaccination sites also accept walk-ins without appointments. Community members also can get the Omicron boosters through their regular healthcare providers or local pharmacies.

For more detailed information about the new booster, see the “Booster Doses” section of CCHS's Vaccine Q&A page.

8/3/22 Update:

New COVID-19 Vaccine, Novavax, Now Available at County-Run Vaccination Clinics in Contra Costa

County-run vaccination clinics in Contra Costa are now offering the recently approved Novavax vaccine for adults who have yet to be immunized.

The Novavax vaccine is different from the Pfizer and Modern vaccines, which use mRNA technology to teach the body to fight against COVID-19. Novavax is a protein-based vaccine similar to others that have been used for decades, such as the hepatitis B and shingles vaccines.

Novavax requires two doses given at least three weeks apart. It has not been approved by the FDA for use as a booster, so it is only available to people ages 18+ who have never gotten a COVID-19 vaccine.

Unvaccinated people can request Novavax when they visit County clinics. To schedule a vaccination appointment, go online or call Contra Costa Health Services at 833-829-2626.

For more information, visit the Contra Costa Health Services About the Vaccine webpage.

6/22/22 Update:

Contra Costa Health Services Now Offering COVID Vaccines to Children Under Age 5

Contra Costa Health Services has announced that County-run vaccination clinics in Contra Costa are now offering safe and effective COVID vaccines to children ages 6 months to 4 years old.

The Food and Drug Administration (FDA), the Centers for Disease Control and Prevention (CDC), and the Western States Scientific Safety Review Workgroup recently authorized pediatric versions of Pfizer’s and Moderna’s vaccines for this age group. Previously, only children ages 5+ and adults were eligible to receive COVID vaccinations.

The pediatric COVID vaccines come in smaller doses than the adult vaccines. Pfizer’s vaccine for this age group is a three-dose series – the first two doses are spaced three weeks apart and the third dose is given eight weeks after that. Moderna offers a two-dose series with each shot given one month apart. 

Parents and guardians can schedule vaccination appointments at county-run vaccination sites, or with their children’s regular healthcare provider. Children must have consent from a parent or adult guardian to receive the vaccine.

Contra Costa Health is also planning a series of mobile vaccination clinics in partnership with local child-development organizations in the coming weeks. CCHS will provide more details about those mobile clinics at a later date.

For more information, visit the CCHS Vaccine for Kids webpage.

6/19/22 Update:

Federal and state health officials have authorized pediatric COVID vaccines for children ages 6 months to 4 years. Previously, COVID vaccine had only been available for kids ages 5+.

About 60,000 residents in the County are in the newly eligible age group. Parents will now be able to choose between two safe and effective pediatric vaccines made by Pfizer (3 doses) and Moderna (2 doses). The pediatric doses are smaller than those given to teens and adults. Children may have mild side effects, such as a sore arm, fatigue, headache, or slight fever, and most pass in one or two days. These are normal signs that their body is building protection. Serious side effects are rare.

Contra Costa Health Services expects to be able to offer immunizations to this age group at County-run vaccination clinics around June 22. For more information, visit the CCHS Vaccine for Kids webpage.

5/17/22 Update:

COVID-19 Treatment at State Testing Sites

This week, Contra Costa Health Services announced that treatment pills are available on-site at State-run testing sites for eligible people who test positive for COVID-19 on antigen/rapid tests.

In addition, free COVID-19 tests are available at county sites, State sites and other commercial and healthcare provider sites. Every home in the U.S. can order free COVID-⁠19 home tests (order online or call 1-800-232-0233).

Contra Costa County Recommends Masks Indoors

With Contra Costa and other Bay Area counties seeing a swell in COVID cases, Contra Costa County health officials are reiterating their strong recommendation to wear masks indoors. Omicron subvariants, which are even more contagious than the original Omicron, are driving the recent increase in cases. Outbreaks in workplaces and schools have also sharply increased in the past few weeks.

While masking remains optional for most public indoor settings, health officials say wearing face covering during periods of increased transmission is a simple best practice to protect against COVID.

“There’s a lot of COVID out there right now, so it’s time to mask up indoors in public again,” said Dr. Ori Tzvieli, health officer for Contra Costa County. Dr. Tzvieli said people should also stay home if they feel sick and get tested. He added that people eligible for booster shots should get one since protection from the COVID vaccines wane over time.

4/7/22 Update:

Quarantine No Longer Recommended for Most People Without Symptoms

As Contra Costa and California transition into a new phase of the pandemic, state health officials no longer recommend quarantine for most asymptomatic people exposed to someone with COVID-19 – regardless of vaccination status.

People exposed to COVID-19 should get tested 3-5 days after their last exposure and wear a well-fitting mask around others for 10 days, especially indoors.

Exposed people who have symptoms should isolate at home and test as soon as possible to determine infection status. Symptomatic people should remain in isolation while waiting for testing results. Anyone who tests positive for COVID-19 will still need to isolate at home for at least five days. If unable to test, they should isolate for at least 10 days.

Those working or living in high-risk settings who are not up-to-date on their vaccinations or who haven’t been infected in the past 90 days still must quarantine for at least five days following an exposure even if they don’t have symptoms. High-risk settings include healthcare sites, emergency shelters and cooling and heating centers, jails, homeless shelters, nursing homes and congregate-care facilities.

The change in quarantine guidance is part of a shift toward co-existing with COVID-19 and minimizing disruptions to daily life. State health officials note that a large majority of California residents now have some protection from COVID-19 through either vaccination or prior infection.

3/30/22 Update:

Second COVID-19 Vaccine Booster Doses Available for Contra Costa Residents Who Are 50+

Contra Costa Health Services (CCHS) now offers second booster doses of COVID-19 vaccine to people who are 50 and older, or who are immunocompromised by certain health conditions.

The U.S. Food and Drug Administration (FDA) has authorized second booster doses of the Moderna or Pfizer vaccines for people in these groups after at least four months have passed since their first boosters.

The U.S. Centers for Disease Control & Prevention (CDC) now recommends a second booster dose for:

Anyone with questions about their eligibility should consult their healthcare provider.

Appointments are available online or by calling 1-833-829-2626.

2/28/22 Update:

State officials have announced they are lifting the requirement that unvaccinated people wear masks in indoor public spaces on March 1. Masking will still be required in high-risk settings, such as hospitals, nursing homes and public transportation regardless of vaccination status.

Masks are no longer required for unvaccinated workers indoors by Cal/OSHA COVID-19 Emergency Temporary Standards (ETS) but are strongly recommended for all individuals in most indoor settings. Employers must still provide a face covering upon request of an employee.

2/9/22 Update:

Contra Costa to Lift Most Indoor Mask Mandates on Wednesday, February 16

In alignment with the State of California, Contra Costa and 10 other Bay Area counties and the City of Berkeley will lift universal mask requirements for vaccinated people in most indoor public settings beginning Wednesday, February 16. The move comes as cases and hospitalizations have begun to rapidly drop around the state and region.

Unvaccinated individuals over age 2 will continue to be required to wear masks in all indoor public settings. Businesses, venue operators and hosts may determine their own paths forward to protect staff and patrons and may choose to require all patrons to wear masks.

Indoor masking is still required by the State for everyone, regardless of vaccination status, in public transportation; health care settings; congregate settings like correctional facilities and homeless shelters; long-term care facilities; and in K-12 schools and childcare settings. Workplaces will continue to follow the COVID-19 prevention standards set by CalOSHA.

Bay Area health officers continue to strongly recommend masks be used as an effective tool to prevent the spread of the virus especially when case rates are high, or when additional personal protection is needed.

2/4/22 Update:

Proof of COVID-19 Vaccination or Recent Test No Longer Required at Restaurants, Gyms in Contra Costa County

With 80% of all county residents now fully vaccinated, Contra Costa Health Services (CCHS) today lifted its health order requiring certain businesses, including restaurants and gyms, to verify the vaccination status or recent negative test results of customers.

Other state and countywide health orders remain in effect, including workplace vaccine verification requirements for healthcare workers, first responders, and congregate care workers, and a requirement for most people to wear face coverings in most indoor public spaces.

Though the county requirement may be lifted, private businesses may choose to implement their own verification requirements to better protect customers and staff, and CCHS encourages them to consider doing so as a safest practice during the pandemic.

Current state health orders still require proof of vaccination or a recent, negative test result in certain situations, including when visiting hospitals or long-term care facilities or attending indoor “mega-events” of 500 or more people.

CCHS continues to urge everyone 5 and older to get vaccinated for the best possible protection from COVID-19 – and especially to receive a booster dose when eligible, as growing local data show boosters provide substantially more protection.

No-Cost COVID-19 Home Test Kits Now Available for Every Household

To ensure that all Americans have access to timely COVID-19 testing, the U.S. Department of Health & Human Services and the U.S. Postal Service have launched, a new site for requesting free home test kits by mail.

Every address in the United States is now eligible to receive four free tests by signing up at the site, which is also a helpful resource for finding nearby COVID-19 testing and vaccination clinics, and information about insurance reimbursement for purchasing home test kits.

Home test kits, also known as rapid antigen tests, are available over the counter at pharmacies. While the polymerase chain reaction (PCR) tests provided at community clinics are the most accurate for detecting COVID-19, antigen tests are the best choice for finding out quickly if someone is contagious right now.

Antigen tests produce a result in about 15 minutes, rather than the days it can take for a laboratory result from a PCR test. They are useful for determining whether a COVID-19 quarantine or isolation period can be shortened, and before visiting to help protect people at high risk of serious illness from COVID-19.

Contra Costa Health Services (CCHS) encourages every household to request test kits from, and any other available source, so they are available in the medicine cabinet when needed.

Antigen tests have been in short supply this winter because of high demand related to the national surge in new COVID-19 cases, as have appointments for testing at community clinics – about twice as many people are getting tested every day in Contra Costa than at any other time during the pandemic.

Learn more about how to get home test kits, or make a testing appointment in Contra Costa, on the Get Tested page.

1/5/22 Update:

Contra Costa County is aligning with new state guidance that allows for shorter isolation and quarantine periods for people who have been infected with or exposed to COVID-19. The state’s new rules are similar to the CDC’s recently revised guidance but add a testing requirement to shorten isolation or quarantine.

People Who Test Positive (Isolation):

  • Isolate for at least 5 days (previously, it was a 10-day minimum)
  • Can end isolation if a test collected on or after day 5 is negative and person doesn’t have symptoms or symptoms are resolving. An over-the-counter antigen test can be used to end isolation.
  • Those who don’t take a test must isolate for 10 days
  • Wear a well-fitting mask around others for a total of 10 days, especially in indoor settings

People Exposed to Someone with COVID-19 (Quarantine):

If unvaccinated or not boosted but eligible for booster:

  • Stay home for at least 5 days after your last contact with person with COVID-19. Test on day 5.

  • Quarantine can end after day 5 if symptoms are not present and test taken on or after day 5 is negative. An over-the counter antigen test can be used to end quarantine.

  • Those who don’t take a test must quarantine 10 days

  • Wear a well-fitting mask around others for a total of 10 days, especially in indoor settings

People who have gotten a booster shot, or are fully vaccinated and not yet eligible for a booster, do not have to quarantine following an exposure. However, they should get tested 5 days after they were exposed to be safe.

These guidelines are for the general public and not healthcare workers, who have their own isolation and quarantine guidance. Workers and K-12 students should also check with their employers and schools about requirements for returning to school or work since state guidance may differ for those settings.

For more information, see California’s guidance for isolation and quarantine or visit the  CCHS For COVID-19 Patients and Contacts page.

12/29/21 Update:

With the highly contagious COVID-19 omicron variant circulating in Contra Costa, Contra Costa Health Services (CCHS) announced a health order requiring everyone to mask in all indoor public settings.

Previously, there were limited exceptions to the indoor masking order. Public speakers and performers, and fully vaccinated groups of up to 100 people were allowed to remove their face coverings under controlled conditions.

As of December 29, the order now requires all people in the county, regardless of vaccination status, to mask in public indoor settings, including but not limited to:

  • Business offices
  • Retail stores
  • Restaurants
  • Gyms and fitness centers
  • Theaters
  • Family entertainment centers
  • Meeting rooms
  • State and local government facilities where services are provided to the public

Religious gatherings remain exempt from the masking requirement to the extent that removal of face coverings is necessary for participation in a religious activity. Also, in alignment with state guidance, performers at indoor live or recorded settings or events such as music concerts or theatrical plays are not required to wear masks.

CCHS strongly urges everyone to get vaccinated and boosted as soon as they are able. Find information on healthcare providers, pharmacies and clinics offering vaccinations and boosters online or by calling 1-833-829-2626.

The requirements for lifting the indoor masking order will remain the same and progress can be tracked on CCHS's Indoor Mask Dashboard.

12/10/21 Update:

On December 9, the U.S. Food and Drug Administration authorized booster shots of the Pfizer-BioNTech coronavirus vaccine for 16- and 17-year-olds, six months after they received their second shot of that vaccine.

CCHS is now accepting booster appointments at all COVID vaccine clinics for teens 16-17. Make an appointment by calling 1-833-826-2929 or online: You can also find appointments at

While people ages 18+ can mix-and-match vaccines for their boosters, teens ages 16-17 will only be able to get Pfizer for their boosters. The Moderna and J&J vaccines are only approved for people ages 18 and older.

Contra Costa County Health Officials Encourage COVID-19 Booster Shots for Adults and Vaccines for Kids Ages 5-11 as Holidays Approach

With the holidays and winter approaching, county health officials are urging everyone to get a COVID-19 vaccine or a booster shot to ensure safe celebrations.

Following guidance from the state health officer, Contra Costa County has announced that it will provide boosters to anyone ages 18+ who feels they are at increased risk from COVID-19 and wants one. According to Contra Costa Health Services, there is increasing evidence that the effectiveness of the vaccines wane over time and boosters provide additional protection.

For those who originally received Pfizer or Moderna vaccines, at least six months must have passed since their last dose. Those who got a Johnson & Johnson vaccine must wait two months to get a booster. 

People may choose any of the three available COVID-19 vaccines for their booster dose when they are eligible, regardless of the vaccine used when they were first vaccinated.

Health officials also strongly urge those who yet to be vaccinated to do so as soon as possible. Kids ages 5-11 recently became eligible for a pediatric version of the COVID-19 vaccine and parents can get their children immunized through their regular healthcare provider, pharmacies, County clinics and, in some cases, at local schools.

Appointments through Contra Costa Health Services (CCHS) are recommended, and can be made online or by phone at 1-833-829-2626. People without appointments are accepted at county-run sites as time and vaccine supply allows.

CCHS Guidance for Safer Holiday Celebrations

CCHS Thanksgiving Recommendations   CCHS Domestic Travel

This holiday season, Contra Costa Health Services (CCHS) encourages everyone to celebrate safely and protect themselves and their loved ones from COVID-19. According to CCHS, getting vaccinated is the best way to lower the risk of getting or spreading COVID-19, especially during holiday gatherings. Visit for locations, appointments and more information.

CCHS also recommends the following key actions to lower your risk:

Get Vaccinated

  • All the vaccines are safe, effective and free for anyone who is 5 or older. 
  • Get your first dose by November 19 to be fully protected for Christmas, Kwanzaa and end-of-year gatherings.
  • You can protect those too young to be vaccinated by making sure those around them are vaccinated

Wear a Mask

  • Wear a well-fitted mask over your nose and mouth if you’re in public indoor spaces.
  • A mask is required in most indoor public spaces in Contra Costa County, regardless of vaccination status.

Get Tested

  • Attending a gathering or event increases your chance of being exposed to COVID-19.
  • Testing is a healthy choice for people who attend gatherings – whether or not they develop symptoms.
  • Three to seven days after a gathering is the best time to test.
  • If you think you’ve been exposed to COVID-19 or develop symptoms, learn when to quarantine and isolate

Take Precautions if You Travel

  • If possible, delay travel if you are not vaccinated or feeling sick.
  • Masks are required on public transportation, such as planes and buses.
  • Avoid crowds.
  • Get tested before and after your trip.

Safer Celebrations

  • Gathering virtually or in-person only with people you live with is the safest choice. If you do gather with others:
  • Smaller gatherings are safer than larger ones.
  • Outdoors is safer than indoors.
  • Avoid crowded, poorly ventilated spaces.
  • If you gather indoors, open windows and doors to bring in fresh air, or put a fan in an open window.
  • If you feel sick, stay home and don’t host any gatherings.

How can I protect my unvaccinated family members?

  • Get vaccinated yourself.
  • Be sure everyone in your family who is 5 or older is fully vaccinated.
  • Wear a mask. You might choose to have everyone at your gathering wear a mask, regardless of vaccination status.

11/3/21 Update:

COVID vaccines are now available for children ages 5 - 11. Community healthcare providers, local pharmacies, and Contra Costa Health Services (CCHS) will all begin vaccinating county residents in this age group this week. The FDA, CDC, and the Western States Scientific Safety Review Work Group have all found that Pfizer’s vaccine is safe and highly effective for children aged 5 to 11. About 92,000 children in Contra Costa are newly eligible for the COVID-19 vaccine.

The pediatric dose is one-third the dosage given to teens and adults, and smaller needles will be used. As with adults, children ages 5-11 must still get two shots at least three weeks apart to get the maximum protection of the vaccine.

Appointments for children aged 5 to 11 will become available anywhere in the county that provides the COVID-19 vaccine in the coming days. Check with your child's pediatrician or primary care provider and ask if they have the vaccine.

CCHS will begin providing the Pfizer vaccine to 5- to 11-year-olds at their no-cost public health vaccination clinics in Antioch, Concord, and Richmond beginning on Friday. Contra Costa Regional Medical Center & Health Centers will begin vaccinating its patients on Monday. Appointments at their clinics in Antioch, Concord, and Richmond will be available beginning Thursday afternoon online or by calling 1-833-829-2626.

11/1/21 Update:

Today, Contra Costa Health Services (CCHS) announced that it has pre-ordered thousands of pediatric doses of Pfizer's COVID-19 vaccine as the county prepares for Federal and State health officials to expand eligibility to kids ages 5-11.

According to a press release, CCHS expects to receive about 20,000 doses of the pediatric version of the Pfizer vaccine for county and partner clinics early this week. Other healthcare providers and pharmacies are also stocking up and getting ready.

CCHS is also working with education and healthcare partners in the region – including John Muir Health, Kaiser, La Clinica and Lifelong Medical – to host vaccine clinics at school sites once eligibility expands to younger kids. More details about school-based vaccine clinics will be announced soon.

The timing of when the vaccine becomes available to younger children depends on when Federal and State officials complete their review process. On Friday, October 29, the Food & Drug Administration (FDA) approved the Pfizer COVID-19 vaccine for emergency use in children ages 5-11.

This week, the Centers for Disease Control & Prevention (CDC) will be deciding whether to recommend Pfizer's COVID-19 vaccine next week for children ages 5-11. The CDC's recommendation is required before vaccines can be given to this age group.

If the CDC recommends the vaccine for the younger age group, it may take a couple of days until immunization clinics actually begin administering the pediatric vaccines, according to CCHS. The Western States Scientific Safety Review Workgroup, a regional collaborative of scientists from several states including California with expertise in immunization and public health, must also weigh in after the CDC makes it decision.

Parents should check with their child's regular healthcare provider or local pharmacies about availability. CCHS expects to begin offering the pediatric vaccine by Nov. 6 at county-run vaccination clinics.

The pediatric COVID-19 vaccine, which is one-third the dosage given to teens and adults, will come in different vials and packaging than the adult version. Like with adults, children ages 5-11 still must get two shots at least three weeks apart to get the maximum protection of the vaccine, which was shown to have a 90.7% efficacy rate in clinical trials among this age group.

10/25/21 Update:

Many Contra Costa residents who received Johnson & Johnson or Moderna COVID-19 vaccines can now consider booster doses – of any vaccine they prefer – for increased protection heading into this holiday season.

After reviewing research, the Centers for Disease Control &Prevention (CDC) and California Department of Public Health (CDPH) have found that booster doses of all available COVID-19 vaccines are not only safe, but significantly improve protection against both infection and serious illness, including from the delta variant.

Fully vaccinated people may also now choose any of the three available COVID-19 vaccines for their booster doses when they are eligible, regardless of the vaccine used during their initial immunization.

Contra Costa Health Services (CCHS) now recommends that anyone who received Johnson & Johnson vaccine and is 18 or older to get a booster dose two or more months after their first dose.

As with people vaccinated with the Pfizer vaccine, those who received Moderna vaccine should get a booster dose, according to the CDC, if at least six months have passed since they completed their initial course of vaccination, and they are:

People previously vaccinated with Moderna vaccine who may consider receiving a booster, based on their individual benefits and risks, include:

  • those who are 18 to 49 with underlying health conditions
  • those who are 18 to 64 and are at increased risk of COVID-19 exposure due to their occupation or institutional setting

According to CCHS, the best place for most Contra Costa residents to seek booster doses is through their own healthcare providers or their local neighborhood pharmacies. COVID-19 vaccine is now plentiful, and CCHS is in regular communication with community healthcare providers, clinics and pharmacies to ensure that all eligible residents can access vaccine.

Beginning Tuesday, October 26, CCHS' free vaccination clinics will also offer booster doses by appointment to anyone who is eligible. Call 1-833-829-2626 to make an appointment, or use the online form at

10/14/21 Update:

Today, Contra Costa Health Services announced that, due to declining COVID-19 cases and hospitalizations, Contra Costa County will lift masking requirements on Nov 1 in certain indoor settings where everyone is fully vaccinated.

Eligible settings are in controlled spaces not open to the general public, including officesgyms and fitness centersemployee commuter vehiclesindoor college classes and organized gatherings in any other indoor setting, such as a religious gathering.

Under the order, participating businesses, organizations and hosts must verify that all patrons, employees and attendees are fully vaccinated before allowing people inside their facilities not to wear face coverings. There can be no more than 100 persons present at these facilities, and the group of those present must gather on a regular basis. Those present should also not have COVID-19 symptoms.

Indoor-masking requirements would remain in effect for the time-being in public settings, such as bars, restaurants and retail stores until other targets are met. Masking would also still be required in indoor K-12 school settings.

> Read the full Press Release from Contra Costa Health Services

10/8/21 Update:

Yesterday, Contra Costa County Health Officer Dr. Chris Farnitano announced the criteria that will be used to lift the current indoor-masking order in Contra Costa County:

  • The county reaches the CDC’s moderate (yellow) COVID-19 transmission tier and remains there for at least three weeks; AND

  • There are fewer than 75 COVID-19 hospitalizations in the county; AND

  • One of the following conditions is met:

    • 80% of the total population is fully vaccinated

    • Eight weeks have passed since a COVID-19 vaccine has been authorized for emergency use by federal and state authorities for 5- to 11-year-olds

When these criteria are met – which is projected to be at the end of 2021 or beginning of 2022, according to CCHS – Dr. Farnitano will lift the local masking order, which requires everyone to wear face coverings in indoor public settings regardless of vaccination status. After the local masking order is lifted, unvaccinated residents will still need to wear masks in indoor public settings under the state’s face-covering order.

Other COVID-19 related health orders that are in place at that time would not be affected, including the health order related to verifying vaccination or testing status at high-risk businesses.

Contra Costa County is currently in the CDC's substantial (orange) COVID-19 transmission tier.

As of October 8, 66 people were hospitalized with COVID-19 in Contra Costa County.

As of October 8, 71.3% of all Contra Costa residents have been fully vaccinated against COVID-19. (This number reflects total population; earlier statistics reflected vaccination rates for those who were 12 and older.)

9/27/21 Update:

Some groups of Contra Costa residents who have received Pfizer’s COVID-19 vaccine can now consider a booster dose if at least six months have passed since they were fully vaccinated.

According to Contra Costa Health Services (CCHS), Pfizer and the other available COVID-19 vaccines continue to provide excellent protection against infection, and especially against serious illness from the virus. But, as with most vaccines, their protection diminishes over time.

Scientists have been researching how long high levels of protection will last. After reviewing the research, federal and state health experts have determined that some people who received Pfizer vaccine should get a booster, including:

Others vaccinated with Pfizer who are now eligible for booster doses include people 18 or older with underlying health conditions, or who are at increased risk of exposure to the virus due to their work or living situation. Read the California Department of Public Health guidelines for more information.

CCHS does not yet have health guidance for any other groups who received Pfizer vaccine, or those who received Moderna or Johnson & Johnson (Janssen) – research continues for those vaccines.

If you are fully vaccinated, it is not urgent to get a booster dose – you still have excellent protection against COVID-19.

But if you are eligible, Contra Costa Health Services (CCHS) recommends checking with your healthcare provider about how to get a vaccine. Many options for COVID-19 vaccine are easily available across the county, including healthcare providers and local pharmacies. Visit the CCHS Get Vaccinated page for information and links to healthcare providers and pharmacies that provide COVID-19 vaccine near you. Appointments are also available at CCHS clinics, online, or by calling 1-833-829-2626.

9/17/21 Update:

Starting Sept. 22, 2021, everyone 12 years and older must show proof of full COVID-19 vaccination, or a negative test result, before going to high-risk indoor businesses such as restaurants, bars and gyms in Contra Costa County. Workers at these businesses must be fully vaccinated or test weekly, starting Nov. 1, 2021.

8/24/21 Update:

Today, Contra Costa Health Services updated the county’s Mass Quarantine Order, and Contra Costa residents exposed to someone with COVID-19 can now narrow down the number of days they must spend in quarantine by testing for the virus at the right time.

Close contacts of persons diagnosed with COVID-19 are required to quarantine themselves, with exceptions for certain persons fully vaccinated with a COVID-19 vaccine, certain essential workers in critical infrastructure sectors, and students in K-12 school settings under specified circumstances. This updated Health Order provides an additional exception, allowing persons who are required to quarantine to end the quarantine period after day 7 instead of after day 10 if they are asymptomatic and test negative for the COVID-19 virus on or after the sixth day after the last date of exposure, consistent with guidance issued by the California Department of Public Health (CDPH).

8/2/21 Update:

Today, eight Bay Area Health Officers announced health orders requiring all individuals, regardless of vaccination status, to wear face coverings when indoors in public settings, with limited exceptions, starting at 12:01 a.m. on Tuesday, August 3, in order to slow the spread of the more contagious Delta variant of COVID-19.

“Vaccination continues to protect against severe COVID-19 illness,” according to a press release from Bay Area Health Officers, “but with the COVID-19 Delta variant now infecting a small percentage of vaccinated people as well as many unvaccinated people, eight Bay Area health officers have issued health orders requiring masks indoors in public places.”

“Vaccines remain the most powerful tool in the fight against COVID-19, including the Delta variant,” states the press release. “Nonetheless, the Delta variant is infecting a small percentage of the vaccinated in the Bay Area — who still remain strongly protected against severe illness, hospitalization, and death. In those instances of infection in a vaccinated person, a face covering prevents further spread.”

Public settings where face coverings must be worn include, but are not limited to, business offices, retail stores, restaurants, theaters, family entertainment centers, meeting rooms and State and local government facilities where services are provided to the public.

This order does not apply to people in the following circumstances:

  • When alone in a room.
  • When actively eating or drinking.
  • When swimming or showering.
  • When receiving care or other service that requires removal of the face covering, including by way of example and without limitation, medical care requiring exposure of the nose or mouth, cosmetic services involving the face, and dental procedures.
  • When exempt from wearing face coverings under the State Face Covering Guidance or other applicable California Department of Public Health (CDPH) guidance. The State Face Covering Guidance exempts the following individuals from wearing masks:
    • Persons younger than two years old. Very young children must not wear a mask because of the risk of suffocation.
    • Persons with a medical condition, mental health condition, or disability that prevents wearing a mask, including persons with a medical condition for whom wearing a mask could obstruct breathing or who are unconscious, incapacitated, or otherwise unable to remove a mask without assistance.
    • Persons who are hearing impaired, or communicating with a person who is hearing impaired, where the ability to see the mouth is essential for communication.
    • Persons for whom wearing a mask would create a risk to the person related to their work, as determined.

Bay Area health officials also urge all unvaccinated residents 12 and older to get vaccinated as soon as possible.
