What about people who are immunocompromised? 

  • People who are immunocompromised and received Pfizer or Moderna at least 28 days ago should receive a 3rd dose.
  • Note: Moderna 3rd dose is a full dose, Moderna booster is a half dose. Please select the appropriate appointment type when scheduling. You must have one of these conditions to receive a 3rddose, all others should receive a Booster dose.
    • Eligible conditions include:

      • Receipt of solid-organ or recent hematopoietic stem cell transplants
      • Severe primary immunodeficiency
      • Advanced or untreated HIV infection
      • Active treatment with high-dose corticosteroids, alkylating agents, antimetabolites, tumor-necrosis (TNF) blockers, and other biologic agents that are immunosuppressive or immunomodulatory
      • Chronic medical conditions such as asplenia and chronic renal disease may be associated with varying degrees of immune deficit

Why are booster shots recommended for certain groups now?

    • People’s responses to their initial vaccination vary. Younger people, for example, tend to produce more antibodies to begin with than older adults. That means months later when antibody levels have naturally declined, some people may still have enough to fend off infection while others don’t. 
    • All approved COVID-19 vaccines main purpose is to prevent severe illness, hospitalization and death. 
      • The COVID-19 vaccines used in the U.S. still offer strong protection against severe COVID-19. However, with the Delta variant, public health experts are starting to see reduced protection against mild and moderate illness. Individuals with “breakthrough” cases can spread COVID-19 to others. 

Here’s what you can do now:

  • If you are eligible, booster vaccines are available throughout the County. Please see the schedule below or to find a provider close to home
