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.

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 12+ 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 receiving the second Pfizer-BioNTech or Moderna shot or the first Johnson & Johnson/Janssen
**Individuals aged 12-17 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.
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 12-17 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.
“Third 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 doses are provided to individuals with compromised immune systems for whom the original vaccine dose was not sufficient to achieve protection from the virus.
Yes, the COVID-19 vaccine and flu vaccine may be given at the same time.
Early data suggest that the COVID-19 vaccines are highly likely to provide antibody protection against the Omicron variant, especially for individuals who have received a booster dose in addition to primary vaccination.
Although “breakthrough” infections of the Omicron variant are expected in vaccinated individuals, experts are cautiously optimistic that these will result in much less severe illness, due to the protection from the COVID-19 vaccine. People who are unvaccinated continue to be at much higher risk of infection and severe outcomes from infection with ANY strain of SARS-CoV2, another reason vaccination and booster shots are encouraged for all eligible individuals.
At this time, it appears unlikely that a new vaccine will be required for Omicron. Nevertheless, Pfizer-BioNTech and Moderna report that they have begun developing an Omicron-specific vaccine, should the Omicron variant prove to require one.
Stanford Medicine has access to all 3 vaccine manufacturers and can help you obtain J&J if necessary. Please discuss this with your healthcare provider to determine if you should receive a J&J dose.
Vaccination for ages 5-11
Children aged 5-11 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.
Vaccine trials for children younger than 5, using even smaller doses, are ongoing.
