COVID 19 Vaccine Booster Shots - Frequently Asked Questions

Are the COVID booster shots safe?
FDA and CDC have determined these booster shots are safe and effective, based on the latest data and evidence, after a thorough, independent, and transparent review process.

Who should get a booster?
Everyone ages 18 and older should get a booster shot either when they are 6 months after their initial Pfizer or Moderna series or 2 months after their initial Johnson & Johnson’s Janssen vaccine, especially the following groups:

  • 65 years and older
  • Age 18+ who live in long-term care settings
  • Age 18+ who have underlying medical conditions
  • Age 18+ who work or live in high-risk settings

Will booster shots be the same formulation as existing vaccines?
Yes, COVID-19 booster shots are the same formulation as the current COVID-19 vaccines. However, in the case of the Moderna COVID-19 vaccine booster shot, it is half the dose of the vaccine people get for their initial series.

Can people mix and match vaccine brands for their booster shot?
Eligible 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. If you have lost your CDC COVID-19 Vaccination Record card or don’t have a copy, contact your vaccination provider directly to access your vaccination record. Additional information about your COVID-19 vaccine record can be found here.

Will the booster shot also be free?
COVID-19 vaccines are available for everyone at no cost, including the booster shot. Vaccines will continue to be given to all people living in the United States, regardless of insurance or immigration status.

Will providers accept anyone who says they’re eligible to receive a booster shot? Will people need to show a doctor’s note/prescription or other documentation?
Individuals can self-report that they are eligible and receive a booster shot wherever vaccines are offered. This will help ensure there are not additional barriers to access for this vulnerable population receiving their booster shot.

Does this change the definition of “fully vaccinated” for those eligible for booster shots?
No. At this time, people are still considered fully vaccinated two weeks after their second dose in a 2-dose series, such as the Pfizer or Moderna vaccines, or two weeks after a single-dose vaccine, such as the J&J/Janssen vaccine.

Where will boosters be available?
Boosters are available through most local pharmacies  If you are unable to get the booster at your original vaccine location, vaccines.gov can make the process easier.

You can also text your zip code to 438829, or call 1-800-232-0233 to find locations near you in the U.S.

Is it safe to co-administer COVID-19 vaccines with other vaccines, like flu? 
Yes, if a patient is eligible, both flu and COVID-19 vaccines can be administered at the same visit, as recommended by CDC and ACIP. In addition to flu vaccine, COVID-19 vaccine can be given with other vaccines as well.
