People Who Are Immunocompromised
If you are immunocompromised, you have a weakened immune system and are more susceptible to severe illness and death from COVID-19.
Vaccines and Booster Doses for Moderately or Severely Immunocompromised People
It is especially important for you to stay up to date with your vaccinations and boosters if you have a weakened immune system. You may find that your response to the vaccine is not as strong as that of people who are not immunocompromised.
There are specific vaccination recommendations for children ages 5-11 and for pre-teens, teens, and adults who are moderately or severely immunocompromised.
Booster doses are recommended for anyone over age 12 after completing their primary vaccine series, even if they were younger than 12 at that time.
Read the CDC guidance for COVID-19 vaccination for people who are moderately or severely immunocompromised.

You are immunocompromised if you have the following conditions or have experienced the following treatments:
- Active cancer treatment for tumors or cancers of the blood

- Moderate or severe primary immunodeficiency (such as DiGeorge syndrome, Wiskott-Aldrich syndrome)

Latest Updates
- Due to flooding, the 550 Broadway drive-thru COVID-19 testing and vaccination sites in Redwood City have closed permanently.
For mild respiratory symptoms, testing before travel or a medical procedure, or if you've been exposed to someone with COVID-19, please consider using an at-home antigen test (which is normally the best course even when PCR testing is available).
If you need medical testing beyond COVID-19 testing, please contact your primary care provider.
We apologize for any inconvenience this may cause you and your family. If you have any questions, you may call (650) 498-9000.
