CDC Vaccines

Excerpt from CDC Website

According to the CDC.gov website – Yes. COVID-19 booster shots are the same ingredients (formulation) as the current COVID-19 vaccines. However, in the case of the Moderna COVID-19 vaccine booster shot, the dose is half of the amount of the vaccine people get for their primary series.

What to Expect during and after Your Booster Shot Appointment

  • Bring your CDC COVID-19 Vaccination Record card to your booster shot appointment so your provider can fill in the information about your booster dose. If you did not receive a card at your first appointment, contact the vaccination site where you got your first shot or your state health department to find out how you can get a card.
  • You may experience side effects after getting a COVID-19 vaccine. These are normal signs that your body is building protection against COVID-19.
  • If you have enrolled in v-safe, enter your booster shot in your v-safe account, the system will send you daily health check-ins. You will be able tell CDC about any side effects.
  • A person is considered “boosted” and up to date right after getting their booster dose.

Data Supporting Need for a Booster Shot

Studies show after getting vaccinated against COVID-19, protection against the virus and the ability to prevent infection with variants may decrease over time and due to changes in variants.

  • Although COVID-19 vaccines remain effective in preventing severe disease, recent data pdf icon[1 MB, 68 pages] suggest their effectiveness at preventing infection or severe illness wanes over time, especially in people ages 65 years and older.
  • The recent emergence of the Omicron variant further emphasizes the importance of vaccination, boosters, and prevention efforts needed to protect against COVID-19.
  • Data from clinical trials showed that a booster shot increased the immune response in trial participants who finished a Pfizer-BioNTech or Moderna primary series 6 months earlier or who received a J&J/Janssen single-dose vaccine 2 months earlier. With an increased immune response, people should have improved protection against getting infected with COVID-19. For Pfizer-BioNTech and J&J/Janssen, clinical trials also showed that a booster shot helped prevent severe disease.
