UPDATE: New Information About Vaccine Third Doses & Booster Shots

The Mississippi State Department of Health and local pharmacies are administering third doses of vaccines. Currently, third doses are only available for Pfizer and Moderna vaccines.

These vaccines are currently available to people who are advised by their doctor to get the third dose and for people who are immunocompromised.

Immunocompromised conditions include:
• Advised by a doctor to get a third dose/booster vaccine
• Been receiving active 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 steroids or other drugs that may suppress your immune response.

*An FDA committee now recommends a booster shot of the vaccine for people 65 and older or at high risk of severe COVID-19.

*What’s the difference between a booster dose and an additional dose?
Sometimes people who are moderately to severely immunocompromised do not build enough (or any) protection when they first get a vaccination. When this happens, getting another dose of the vaccine can sometimes help them build more protection against the disease. This appears to be the case for some immunocompromised people and COVID-19 vaccines. CDC recommends moderately to severely immunocompromised people consider receiving an additional (third) dose of an mRNA COVID-19 vaccine (Pfizer-BioNTech or Moderna) at least 28 days after the completion of the initial 2-dose mRNA COVID-19 vaccine series.

In contrast, a “booster dose” refers to another dose of a vaccine that is given to someone who built enough protection after vaccination, but then that protection decreased over time (this is called waning immunity). HHS has developed a plan to begin offering COVID-19 booster shots to people this fall. Implementation of the plan is subject to FDA’s authorization and ACIP’s recommendation.
