vaccine TYPES

Three COVID-19 vaccine options are available in the United States. The California Department of Public Health (CDPH) has provided a factsheet to help choose the right vaccine for you and your family. 

Some age groups may only be eligible for certain vaccine types.

See below for more information about each vaccine's risks and benefits:

BOOSTER eligibility and recommendations

Booster doses of vaccines are very common. They are part of most childhood and adult vaccine series to ensure a person maintains optimal immunity against infection from a disease. This also applies to COVID-19 vaccinations.

CDPH COVID-19 Booster Questions & Answers Sheet              COVID-19 Vaccine & Booster Timeline Guide


Ages 5-11

A Booster dose of the Pfizer vaccine is available to those ages 5-11 who completed their primary vaccine series at least 5 months ago. 

Ages 12-17

A Booster dose of the Pfizer vaccine is available to those ages 12-17 who received their second dose of Pfizer at least 5 months ago.

Age 18 and older

People in this age group can receive a Booster dose of their choice if the minimum time has passed since completing their primary vaccine series:

  • Pfizer or Moderna - Received the second dose at least 5 months ago
  • Johnson & Johnson - Received single dose at least 2 months ago

Second Dose Booster recommendations are as follows:

Ages 50 and Older

Effective 3/31/22, Second Dose Boosters are now available for those 50 years and older.  Individuals in this group that are considered high risk are advised to get their second booster as soon as possible (as long as it is at least 4 months after the first booster).   

NOTE: *If an individual falls into this group but is not considered high risk, they may choose to wait for their second booster until cases start to increase again, and/or speak with their healthcare provider for more guidance.

Under Age 50 - Only if Immunocompromised:

Effective 3/31/22, Second Dose Boosters are now available for those under age 50 who are immunocompromised and received their first booster at least 4 months ago.

If you are unsure if you qualify, please reach out to your healthcare provider.

Mixing & Matching Boosters

Individuals ages 18 and older can receive the booster dose of their choice, following the completion of their primary vaccination series. 

NOTE: *It is recommended that if you received a J&J vaccine, that you strongly consider a Pfizer or Moderna booster

CDC’s recommendations allow for this type of mix and match dosing for booster shots.

Are Vaccines Safe?

The U.S. vaccine safety system ensures that all vaccines aren't only effective, but are as safe as possible. Safety is a top priority while federal partners work to make the COVID-19 vaccines available.

  • COVID-19 vaccines were developed using science that has been studied and reviewed for decades.
  • COVID-19 vaccines are safer than getting a natural COVID-19 infection.

Even under Emergency Use Authorization (EUA), the safety measures were not ignored or skipped. You can learn more about the process here.

You can review information on potential adverse reactions here.

Why Should I Get Vaccinated?

We understand that some people may be concerned about getting vaccinated for a variety of reasons. While these vaccines were developed as quickly as possible, routine processes and procedures remain in place to ensure the safety of any vaccine that is authorized or approved for use. Safety is a top priority, and there are many reasons to get vaccinated.

  • COVID-19 vaccination can help keep you from getting COVID-19.
  • COVID-19 vaccination can decrease the risk of hospitalization or death if you do become infected.
  • COVID-19 vaccination is a safer way to help build protection.
  • COVID-19 vaccination is an important tool to help end the pandemic.

Learn more about why you should get a vaccine on the CDC's website.

Vaccines are another tool in our toolkit

While the vaccine is not 100% effective, we must use all the tools we can to layer on protection for our community. Our main goal is to help stop this pandemic. We can achieve that by using the tools we have such as:

  • Vaccination
  • Proper hand hygiene
  • Social distancing
  • Proper mask-wearing 
  • Staying home when sick
  • Testing


Additional doses of the COVID-19 vaccine are available to those age 5 and older who completed their Pfizer or Moderna series at least 28 days ago and who are moderately or severely immunocompromised. This includes people who have:

  • 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

Please talk with your healthcare provider about your medical condition, and whether getting an additional dose is appropriate for you at this time.

V-Safe Phone App

Use your smartphone to tell CDC about any side effects after getting the COVID-19 vaccine. You’ll also get reminders if you need a second vaccine dose.

V-safe is a smartphone-based tool that uses text messaging and web surveys to provide personalized health check-ins after you receive a COVID-19 vaccination. Through v-safe, you can quickly tell CDC if you have any side effects after getting the COVID-19 vaccine. Depending on your answers, someone from CDC may call to check on you and get more information. And v-safe will remind you to get your second COVID-19 vaccine dose if you need one.
