The Alameda County Public Health Department is now recommending that immunocompromised individuals schedule a third dose of the COVID-19 vaccination. Third doses are authorized for moderately to severely immunocompromised people who have received two doses of the Moderna or Pfizer vaccines (mRNA vaccines). This is not recommended for those who received the one-shot Johnson & Johnson vaccine.
Immunocompromised individuals are encouraged to speak with their health care provider before getting the third dose, and they must sign a self-attestation indicating that they qualify. The attestation form can be signed electronically when making an appointment. Individuals must wait until at least 28 days have passed since receiving their second dose of the vaccine, and they need to register for the same vaccine that they have already received (e.g., two doses of Moderna must be followed by a third dose of Moderna).
