The best protection against COVID-19
If you’re fully vaccinated and boosted, you have the best chance of staying healthy. You also minimize your chances of becoming seriously ill with COVID-19 and hospitalization.
If you’ve been ill with COVID-19, you still need vaccinations and boosters
A case of COVID-19 does not make you immune to further infections with variants of the virus. Get all your recommended vaccinations and boosters.

Vaccination for ages 6 months - 11 years old
Children aged 6 months - 11 years old will receive a smaller dose of the Pfizer/BioNTech vaccine, using smaller needles. The dose for these children is 10 micrograms, one-third of that used in teens and adults. Children’s immune systems are more responsive than those of adults and in clinical trials, the smaller dose was found to produce a robust immune response.
Children will receive two doses of the Pfizer-BioNTech vaccine spaced three weeks apart, the same timing as for older age groups.
For more information on the pediatric COVID-19 vaccine, read our Pediatric Vaccine FAQs.
For more information on booster doses for immunocompromised patients age 6 months+, view the CDC guidance.
The Centers for Disease Control & Prevention (CDC) recommends COVID-19 booster shots to certain groups of people based on their age, health condition or occupation, and also to anyone who received the Johnson & Johnson/Janssen COVID-19 vaccine at least two months ago.
Boosters can be scheduled for:
- Individuals 5+ who received a Pfizer-BioNTech vaccine at least five months after their second dose
- Individuals 18+ who received a Moderna COVID-19 vaccine at least five months after their second dose
- Individuals 18+ who received the Johnson & Johnson/Janssen COVID-19 vaccine at least two months ago
- Individuals who are immunocompromised should schedule a booster dose 28 days after completing the number of recommended primary doses
**Individuals aged 5-17 can only receive the Pfizer-BioNTech booster. Individuals aged 18 and older may choose which vaccine they receive as a booster dose.
**Individuals with recent COVID-19 infection may receive their booster dose after their symptoms resolve and they have met criteria to discontinue isolation per CDC guidelines.
Please refer to this CDC chart of information about all three COVID-19 boosters.
The Centers for Disease Control and Prevention (CDC) issued guidelines on February 11, 2022 for immunocompromised people. Those who fall in this category and who've had the mRNA vaccines (Pfizer/BioNTech or Moderna) should get a fourth shot (booster dose) at least three months after completing the three-dose primary series. For those who've had the Johnson & Johnson/Janssen vaccine, an mRNA dose is recommended at least 28 days after the first shot, followed by a third dose at least two months later.

Immunocompromised people who received their first booster dose at least 4 months ago may now receive a second booster dose as well:
- Those 18 and over can receive either of the mRNA vaccines (Moderna or Pfizer/BioNTech) as a second booster
- Those age 5-17 are limited to Pfizer/BioNTech as their second booster
Stanford Health Care patients who are eligible for additional doses can schedule their appointments through MyHealth now.
Individuals with recent COVID-19 infection may receive their booster dose after their symptoms resolve and they have met criteria to discontinue isolation per CDC guidelines.
- Individuals aged 5-17 can only receive the Pfizer-BioNTech booster.
- Individuals aged 18 and older may choose which vaccine they receive as a booster dose.
Recommendations by the Centers for Disease Control and Prevention now allow for mix-and-match dosing for booster shots.
Please refer to this CDC chart of information about all three COVID-19 boosters.
You can book an appointment for the vaccine at one of our vaccination clinic sites by calling 650-498-9000 or via MyHealth.
“Additional doses” are different than a “booster dose.” A booster is an added dose of a vaccine that is given to someone with a healthy immune system who built enough protection after being fully vaccinated. If that protection gradually decreases, a booster can help sustain it. Third or fourth doses are provided to individuals with compromised immune systems for whom the original vaccine dose was not sufficient to achieve protection from the virus. For more information on new CDC guidance on COVID-19 vaccine additional doses for immunocompromised people, click here.
Yes, the COVID-19 vaccine and flu vaccine may be given at the same time.
The new boosters are “bivalent,” meaning they contain a combination of the original formulation and one targeting BA.5 and BA.5, now the dominant version of the virus, as well as a sister subvariant of Omicron.
Individuals who have been fully vaccinated against COVID-19 are eligible for the updated shots if they meet the age requirements (12+ for Pfizer, 18+ for Moderna), regardless of whether they have also received booster doses. Your last shot (booster or original vaccine dose) must have been at least two months ago.
