“Do “not get the” J&J “vaccine if you had a severe allergic reaction to any ingredient of this vaccine.”
FACT CHECKED BY Emilia Paluszek

We now have a third COVID-19 vaccine, from Janssen Pharmaceuticals—most commonly referred to by its parent company, Johnson & Johnson. So is it safe and effective, and is there anyone who should not take it? We consulted the official fact sheet from the makers of the vaccine to see who should not take the vaccine—and why it could benefit those who can. "The Janssen COVID-19 Vaccine may prevent you from getting COVID-19," it says, but one small group of people should avoid it. Read on—and to ensure your health and the health of others, don't miss these Sure Signs You've Already Had Coronavirus

What Are the Risks of the J&J Vaccine?

"Side effects that have been reported with the Janssen COVID-19 Vaccine include: 

  • Injection site reactions: pain, redness of the skin and swelling. 
  • General side effects: headache, feeling very tired, muscle aches, nausea, and fever. 

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. For this reason, your vaccination provider may ask you to stay at the place where you received your vaccine for monitoring after vaccination. Signs of a severe allergic reaction can include: 

  • Difficulty breathing
  • Swelling of your face and throat
  • A fast heartbeat
  • A bad rash all over your body
  • Dizziness and weakness. 

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."


So is the J&J Vaccine Safe and Effective?

Yes, says Dr. Anthony Fauci, the chief medical advisor to the President and the director of the National Institute of Allergy and Infectious Diseases. "If you go to a place and you have J&J, and that's the one that's available now, I would take it. I personally would do the same thing," Fauci said on NBC's Meet the Press. "It's not the weaker vaccine." So get vaccinated when it becomes available to you (unless you are allergic to the ingredients), and to protect your life and the lives of others, don't visit any of these 35 Places You're Most Likely to Catch COVID.
