The CDC now recommends that people whose immune systems are moderately to severely compromised should receive an additional dose of mRNA COVID-19 vaccine after the initial 2 doses.

For those who received the Pfizer-BioNTech (i.e., Comirnaty) primary series (2-doses), people age 5 or older should get an additional dose of Pfizer-BioNTech (i.e., Comirnaty) at least 28 days after. For those who received Moderna primary series (2-doses), people age 18 and older should get an additional dose of Moderna at least 28 days after. For those who received Janssen (Johnson and Johnson), no additional primary shot is recommended at this time.

The CDC expanded booster dose eligibility to include anyone age 12 or older at least 5 months after receiving the Pfizer-BioNTech (i.e., Comirnaty) primary series (2-doses), anyone 18 and older at least 5 months after receiving the Moderna primary series (2-doses) and anyone 18 and older who received the Janssen (Johnson and Johnson) vaccine at least 2 months after their one dose to help increase their protection against COVID-19.

Frequently Asked Questions

Additional Dose:
CDC recommends moderately to severely immunocompromised people consider receiving an additional (third) dose of an mRNA COVID-19 vaccine (Pfizer-BioNTech or Moderna) at least 28 days after the completion of the initial 2-dose mRNA COVID-19 vaccine series. For those who received the Pfizer-BioNTech (i.e., Comirnaty) primary series (2-doses), people age 5 or older should get an additional dose of Pfizer-BioNTech (i.e., Comirnaty) at least 28 days after. For those who received Moderna primary series (2-doses), people age 18 and older should get an additional dose of Moderna at least 28 days after. For those who received Janssen (Johnson and Johnson), no additional primary shot is recommended at this time.

Booster Dose:
A Booster dose refers to another dose of a vaccine that is given to someone who built enough protection after vaccination, but then that protection decreased over time (this is called waning immunity). The CDC expanded booster dose eligibility to include anyone age 12 or older at least 5 months after receiving the Pfizer-BioNTech (i.e., Comirnaty) primary series (2-doses), anyone 18 and older at least 5 months after receiving the Moderna primary series (2-doses) and anyone age 18 or older who received the Janssen (Johnson and Johnson) vaccine at least 2 months after their one-dose to help increase their protection against COVID-19.

The CDC now recommends a third vaccine dose for certain groups of people with weakened immune systems who received either the Pfizer-BioNTech or Moderna COVID-19 vaccine. Some examples below.

• Been receiving active cancer treatment for tumors or cancers of the blood
• Received an organ transplant and are taking medicine to suppress the immune system
• Received a stem cell transplant within the last 2 years or are taking medicine to suppress the immune system
• Moderate or severe primary immunodeficiency (such as DiGeorge syndrome, Wiskott-Aldrich syndrome)
• Advanced or untreated HIV infection
• Active treatment with high-dose corticosteroids or other drugs that may suppress your immune response

People should talk to their healthcare provider about their medical condition, and whether getting an additional dose is appropriate for them. See criteria here.

All individuals 12+ who received their 2nd dose of Pfizer-BioNTech (Comirnaty) COVID-19 vaccine at least 5 months ago, all individuals 18+ who received the Moderna COVID-19 vaccine at least 5 months ago OR all individuals 18+ who received a Janssen (Johnson and Johnson) COVID-19 vaccine at least 2 months ago.

There is no required proof outside of a self-attestation. A self-attestation is a statement indicating that you have self-determined that you are eligible to receive an additional dose of a COVID-19 vaccine.

Self-attestation forms are available at every County-run vaccine clinic. To view the self-attestation, please see the following:

All COVID-19 vaccines are approved for booster doses.

Pfizer and Moderna are approved for additional doses.

There are now booster recommendations for all three available COVID-19 vaccines in the United States. Eligible individuals 18 years of age and older may choose which vaccine they receive as a booster dose. Some people may have a preference for the vaccine type that they originally received, and others may prefer to get a different booster. CDC’s recommendations now allow for this type of mix and match dosing for booster shots.

Per the Western States Scientific Safety Review Workgroup:

“Individuals who have previously received an initial series of any of the three COVID-19 vaccines currently approved or authorized for use in the United States are eligible for a booster dose. The Workgroup supports CDC’s decision that individuals eligible for a booster may receive either the same or a different COVID-19 vaccine as a booster dose, depending on advice from a health care provider, individual preference, availability or convenience.”

Please refer to the following media statement from the CDC on Booster Shot Mixing and Matching and the Western States Scientific Safety Review Workgroup statement.

Contact your provider directly to confirm if you need to bring your vaccine card.

If you make an appointment at an SB County Vaccine Clinic or special pop-up event please bring your vaccine card.

If you have lost your vaccine card please refer to this website: https://sbcovid19.com/vaccinecards/.

If it has been at least 28 days (4 weeks) or more since your 2nd dose then you can receive an additional dose of either Pfizer or Moderna.

Moderately and severely immunocompromised people aged 18 years and older who completed an mRNA COVID-19 vaccine primary series and received an additional mRNA vaccine dose may receive a single COVID-19 booster dose (Pfizer-BioNTech, Moderna, or Janssen) at least 5 months after completing their third mRNA vaccine dose.

COVID-19 Boosters California Department of Public Health (CDPH) Recommendation

Who is eligible for booster vaccinations?

A COVID-19 booster dose is recommended following completion of a primary vaccination series. The following ages are eligible for a booster dose:

Pfizer: 12 and older
Moderna: 18 and older
Johnson & Johnson: 18 and older

What is the difference between boosters and additional doses for immunocompromised individuals?

A booster dose is a dose of vaccine that is needed when a person’s level of immunity has decreased over time. Booster doses are very common and are a normal part of most vaccine series.

An additional dose for immunocompromised individuals is necessary after an initial primary vaccine series is likely to be insufficient, and an additional dose can increase a person’s antibody response.

When should I receive a booster dose?

Pfizer Received second dose at least 5 months ago after their initial vaccine series

Moderna Received second dose at least 5 months ago after their initial vaccine series

Johnson & Johnson Received single dose at least 2 months ago after their initial vaccine series

It is recommended that eligible individuals receive a booster as soon as they’re eligible to maintain a strong immunity against COVID-19. You may receive the Booster dose of your choice, following completion of your primary vaccination series. See this COVID-19 Vaccine Eligibility Chart for additional details.

When will booster doses be made available in California?

California began administering booster doses as of September 24, 2021, when Pfizer boosters were first approved, and have been actively working with our partner networks and medical providers to ensure the state is ready to meet demand as boosters are more widely recommended.

Can I receive a booster dose before the recommended time frame?

No, booster doses are authorized for a specific time frame based on the initial vaccine received and its corresponding research and data.

Is a booster dose the same amount of vaccine as doses in the original vaccine series?

The Pfizer and Johnson & Johnson booster doses are the same dosage as the original vaccine received in the series, while the Moderna booster dose will be half dosage compared to the original vaccine series.

How does someone find and receive a booster dose?

Boosters will be available through all current channels, including healthcare providers, clinics and neighborhood pharmacies. Californians can visit the My Turn website (MyTurn.ca.gov) or call 833-422-4255 to make an appointment or find a nearby vaccine clinic.

Which vaccines are covered by the emergency use authorization for booster doses?

All three widely available COVID-19 vaccines have been granted an extended EUA to allow for booster vaccine doses for specific populations.

Can a person get a booster dose from a different manufacturer from their original series, or do they need to stay with the brand for their original supplier?

A single booster dose of any of the available COVID-19 vaccines may be administered as a mix and match (heterologous) booster dose following completion of primary vaccination with a different available COVID-19 vaccine. The eligible populations and dosing interval for a mix and match booster dose are the same as those authorized for a booster dose of the vaccine used for primary vaccination.

For example, Johnson & Johnson (J&J) vaccine recipients 18 years and older may receive a single booster dose of the J&J or Pfizer, or a booster dose of Moderna (half dose) at least two months after receiving their J&J primary vaccination.

In another example, Pfizer vaccine recipients may receive a booster dose of Moderna (half dose), Pfizer or J&J at least five months after completing their primary vaccination.

Californians can receive the booster dose of their choice, but it is recommended that if an individual received a J&J vaccine, they strongly consider a Pfizer or Moderna booster.

Can I get multiple boosters?

No, only one booster dose is recommended at this time. Eligible Californians should receive a booster at least five months after the second dose of their Pfizer or Moderna vaccine series or at least two months after receiving the Johnson & Johnson vaccine.

Will boosters be required to be considered fully vaccinated under the current CA Public Health Orders?

At this time, a person is considered fully vaccinated when they have completed their original vaccine series. Booster doses are not required to be considered fully vaccinated but are strongly encouraged for those that are eligible to ensure significant protection from COVID-19 and its variants.

Will digital vaccine records be updated to show that individuals have received a booster dose?

Yes, the Digital COVID-19 Vaccine Record has been updated and will show that a booster vaccine dose has been administered. Your vaccine record will not automatically update, so a new version will need to be downloaded to reflect that you have received a booster dose.

We recommend waiting 14 days for your new dose to show up in the California Immunization Registry.

If I get a booster dose, will it show on my digital vaccine record?

The QR code on your digital vaccine record does not automatically update. If you receive a booster dose of the COVID-19 vaccine, you’ll have to get a new QR code through the Digital COVID-19 Vaccine Record portal.

We recommend waiting 14 days for your new dose to show up in the California Immunization Registry.

Will an antibody or other test show whether I need a booster dose?

We do not recommend using antibodies or any other tests to determine protection from the virus at this time. There is significant variability from one antibody test to another, and we do not know enough about what antibody levels mean in terms of protection from COVID-19 and its variants.

Does receiving a booster eliminate the need for further harm-reduction precautions?

No, even with a booster dose, harm reduction precautions are still important to keep all Californians safe. Vaccines are not 100% effective, and some groups are not yet eligible for the vaccine, so taking harm reduction precautions such as wearing a face mask helps protect them from contracting COVID-19 and becoming seriously ill.

Should pregnant or recently pregnant individuals receive a booster dose?

Pregnant persons 18-49 years old are eligible and are encouraged to receive a booster dose.

How is California verifying people are getting booster vaccine doses within the recommended time frame mark and not jumping the queue?

California is using self attestation to confirm eligibility for a booster. There is no verification process required to confirm eligibility, though some providers may ask for additional confirmation or eligibility such as verification or age or occupation. California has ample supply to ensure all eligible Californians will have access to the vaccine.

How do we know booster doses are safe?

Booster doses went through the same thorough scientific review process as the initial vaccine series, with trial data from all over the world being reviewed and considered when making a recommendation. The vaccines, including booster doses, are proven safe.

What side effects should be expected after receiving a booster dose?

The side effects from booster doses should be the same mild side effects experienced when receiving the initial vaccine dose. A sore arm at the injection site and mild flu-like symptoms are normal and demonstrate that your body is rebuilding immunity to COVID-19.
