What are the risks of the Janssen COVID‑19 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 1 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

Blood clots involving blood vessels in the brain, abdomen, and legs, along with low levels of platelets (blood cells that help your body stop bleeding), have occurred in some people who have received the Janssen COVID-19 Vaccine. In people who developed these blood clots and low levels of platelets, symptoms began approximately 1 to 2 weeks following vaccination. Most people who developed these blood clots and low levels of platelets were females ages 18 through 49 years. The chance of having this occur is remote. You should seek medical attention right away if you have any of the following symptoms after receiving Janssen COVID-19 Vaccine:

  • Shortness of breath
  • Chest pain
  • Leg swelling
  • Persistent abdominal pain
  • Severe and persistent headaches or blurred vision
  • Easy bruising or tiny blood spots under the skin beyond the site of the injection

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.
