COVID-19 Vaccinations

Vaccine and Booster Eligibility

All community members age 5+ are now eligible to receive a COVID-19 vaccine per WI and MI DHS guidance. The COVID-19 Pfizer vaccine is currently the only one authorized for children and teens age 5-18.

Refer to this COVID-19 vaccine algorithm from the American Pharmacists Association that details vaccine doses, timing and more.

COVID-19 Vaccine Third Dose vs. Booster Dose

Here is a rundown from the CDC that outlines the COVID-19 booster recommendations. Here is a summary of third-dose recommendations.

Third Dose

The CDC recommends individuals who are immunocompromised receive a third dose of the Pfizer or Moderna COVID-19 vaccines at least 28 days after completing their second dose. This includes people who have:

  • Recently received or are currently receiving cancer treatment for tumors or cancers of the blood.
  • Received an organ transplant and are taking medicine to suppress the immune system.
  • Received a stem cell transplant within the last 2 years or are taking medicine to suppress the immune system.
  • Moderate or severe primary immunodeficiency (such as DiGeorge syndrome, Wiskott-Aldrich syndrome)
  • Advanced or untreated HIV infection.
  • Active treatment with high-dose corticosteroids or other drugs that may suppress your immune response.

Booster Dose

A booster dose is different than a third dose of the vaccine.

Booster doses are authorized by the FDA and CDC for everyone age 18+ who received the Pfizer, Moderna or Johnson & Johnson COVID-19 vaccine.

Teens age 16-17 are authorized to receive a booster dose of the Pfizer vaccine.

Individuals are eligible to receive a booster dose of the Pfizer or Moderna vaccine 6 months after completing their original series.

Individuals with weakened immune systems and people age 50 or older are also eligible to receive a second booster at least 4 months after receiving their initial booster.

Adults (18+) who received the Johnson & Johnson vaccine may receive a booster at least 2 months after the initial dose.


Mixing-and-matching: Individuals may choose which vaccine they receive as a booster dose. Some people may have a preference for the vaccine type that they originally received and others, may prefer to get a different booster. CDC’s recommendations now allow for this type of mix and match dosing for booster shots.
