Additional Doses & Boosters
About Boosters & Additional Doses of COVID-19 Vaccine
A COVID-19 booster is given when a person has completed their vaccine series, and protection against the virus has decreased over time. An additional dose, originally called a third dose, is given to people with moderately or severely compromised immune systems [external link] to improve their response to the initial vaccine series. Everyone aged 5 years and older is recommended to get at least two doses of the COVID-19 vaccine. Some people need three doses for the highest level of protection. Others may need to get four or five doses depending on age and underlying medical conditions.
- Everyone ages 5 years and older is recommended to get 1 booster after completing their COVID-19 vaccine primary series [external link] (Pfizer, Moderna, 12+ Novavax or 18+ J&J).
- If you are eligible for an additional dose or booster, you can get one immediately at any vaccination clinic in Jefferson County or other vaccine providers [external link]. You can also talk to your healthcare provider and ask if they are offering COVID-19 vaccines.
- Additional doses and boosters are free. No ID, insurance or proof of medical history is required.
- You may self-report your immunocompromising conditions [external link] or eligibility [external link] to vaccine providers.
Following approval from the Food and Drug Administration (FDA) [external link], and the Center for Disease Control and Prevention (CDC) [external link], the new omicron vaccine doses or boosters, are now available.
- Use the CDC’s COVID-19 Booster Tool [external link] to determine your eligibility for your next COVID-19 vaccine.
- People ages 12 years and older are recommended to receive the omicron dose at least 2 months after completion of primary series or since their last booster dose.
- People ages 18 and older who received Janssen COVID-19 vaccine as both their primary series dose and/or booster dose may receive the omicron dose at least 2 months after their last dose of COVID-19 vaccine.
- When: 5 months after receiving your last dose for children 6 months through 11 years and at least 2 months for those 12 years and older
- Who: Everyone ages 6 months+
- When: 2 months after receiving your last dose
- Who: Everyone ages 18+
In addition, the CDC recommendations allow for “mixing and matching [external link],” meaning individuals have a choice to receive a different vaccine as a booster than what they originally received.
- People ages 6 months through 11 years who are moderately or severely immunocompromised are recommended to receive 3 doses of an mRNA COVID-19 vaccine as a primary series and an additional omicron dose at least 3 months after the last dose of a COVID-19 vaccine.
- People ages 12 years and older who are severely immunocompromised are recommended to receive 3 doses of an mRNA COVID-19 vaccine as a primary series and an additional omicron dose at least 2 months after their last dose of a COVID-19 vaccine.
People who are considered to be moderately to severely immunocompromised may include:
- Those who have been receiving active cancer treatment for tumors or cancers of the blood.
- Have received an organ transplant and are taking medicine to suppress the immune system.
- Have received a stem cell transplant within the last two years or are taking medicine to suppress the immune system.
- Are moderate or severe primary immunodeficiency (such as DiGeorge syndrome, Wiskott-Aldrich syndrome).
- Have advanced or untreated HIV.
- Are undergoing active treatment with high-dose corticosteroids or other drugs that may suppress your immune response.
