Sedgwick County Now Offering COVID-19 Third Dose to those with Moderately or Severely Weakened Immune Systems

(Sedgwick County, Kan.) – On Wednesday, Aug. 18, 2021, Sedgwick County Health Department (SCHD) will begin providing a no-cost third dose of Pfizer vaccine to people who self-attest to having a moderately or severely weakened immune system and who have previously received two doses of vaccine. Documentation of a qualifying condition is not a requirement. People who can receive a third dose should bring documentation of their first and second doses to the vaccine site.

This comes after Pfizer and Moderna third dose approval from the U.S. Food and Drug Administration and guidance from the Centers for Disease Control and Prevention (CDC) and the Kansas Department of Health and Environment (KDHE). People who can receive the third dose have one or more of the following conditions or treatments:

  • Active treatment for solid tumor or hematologic malignancies
  • Receipt of solid-organ transplant and taking immunosuppressive therapy
  • Receipt of CAR-T-cell or hematopoietic stem cell transplant (within 2 years of transplantation or taking immunosuppression therapy)
  • Moderate or severe primary immunodeficiency (e.g., DiGeorge, Wiskott-Aldrich syndromes)
  • Advanced or untreated HIV infection
  • Active treatment with high-dose corticosteroids (i.e., > 20mg prednisone or equivalent per day), alkylating agents, antimetabolites, transplant-related immunosuppressive drugs, cancer chemotherapeutic agents classified as severely immunosuppressive, TNF blockers, and other biologic agents that are immunosuppressive or immunomodulatory

The conditions do not include people who are pregnant, residents of adult care homes, or those with chronic medical conditions unless they have a condition or treatment listed above.

The additional dose is to be administered at least 28 days after the second dose of Pfizer or Moderna vaccine. Third dose guidance only applies to Pfizer and Moderna vaccines. There is not enough data to determine if an additional dose of Johnson and Johnson (J&J) vaccine will improve the immune response in people with weakened immune systems.

“In order to prevent severe illness and/or death during this pandemic, getting vaccinated is the best protection a person can do to protect themselves and loved ones,” says Adrienne Byrne, director of SCHD.
