Third-dose boosters for immunocompromised people

The Food and Drug Administration (FDA) has approved the use of a third “booster” shot of the Pfizer and Moderna vaccines for certain immunocompromised patients. WashU Med is providing the Pfizer vaccine to qualified individuals who originally received this vaccine.

Qualified individuals should seek a third dose of their original vaccine at the Clayton Avenue Building and Christian Hospital public clinics, to be administered at least 28 days following their second dose. Patients may self-attest to their qualifying medical conditions (no doctor’s note required). Online appointment scheduling is expected soon.


Individuals are eligible for a third shot from WashU Med if they originally received the Pfizer vaccine and have one of the following medical conditions: 

  • Active treatment for cancer 
  • Solid-organ (e.g. kidney, liver, heart, lung, liver) transplant 
  • Stem cell or bone marrow transplant 
  • Severe primary immunodeficiency condition 
  • Advanced or untreated HIV infection (CD4 < 200) 
  • Active/ongoing treatment with medications that suppress the immune system  
Boosters for all Pfizer, Moderna recipients

U.S. health officials announced on Aug. 18, 2021, that a third COVID-19 shot will be available beginning the week of Sept. 20 for all Americans who were fully vaccinated with either the Pfizer or Moderna vaccines. The recommendation arises out of concern over the delta variant surge and data suggesting immune protection from vaccination may fade over time. Individuals would receive this third shot — of their original vaccine — about eight months after receiving their second dose.

Alexis Portell, 14, says, “There’s so many traditions that I missed out on this year. … I want to protect everyone else, and I want to have a normal summer and a normal school year next year.”

State and county vaccination
