Third COVID-19 Vaccine Authorized

FDA Issues Emergency Use Authorization for Third COVID-19 Vaccine

On February 27, 2021, the U.S. Food and Drug Administration issued an emergency use authorization (EUA) for the third vaccine for the prevention of coronavirus disease 2019 (COVID-19). The EUA allows the Janssen COVID-19 Vaccine to be distributed in the U.S for use in individuals 18 years of age and older for the prevention of COVID-19.

The Janssen COVID-19 Vaccine is administered as a single dose, into the muscle.

Janssen has put together a Janssen COVID-19 Vaccine Information Sheet which provides details about the vaccine and important safety information. Below are some frequently asked questions from the fact sheet. Remember, talk to your doctor if you have additional questions.

There is a remote chance that the Janssen COVID-19 Vaccine could cause a severe allergic reaction. A severe allergic reaction would usually occur within a few minutes to one hour after getting a dose of the Janssen COVID-19 Vaccine.

Signs of a severe allergic reaction can include:

  • Difficulty breathing,

  • A fast heartbeat,
  • A bad rash all over your body,

These may not be all the possible side effects of the Janssen COVID-19 Vaccine. Serious and unexpected effects may occur. The Janssen COVID-19 Vaccine is still being studied in clinical trials.

WHAT SHOULD I DO ABOUT SIDE EFFECTS?

If you experience a severe allergic reaction, call 9-1-1, or go to the nearest hospital. Call the vaccination provider or your healthcare provider if you have any side effects that bother you or do not go away. Report vaccine side effects to FDA/CDC Vaccine Adverse Event Reporting System (VAERS). The VAERS toll-free number is 1-800-822-7967 or report side effects online. Please include “Janssen COVID-19 Vaccine EUA” in the first line of box #18 of the report form.
