CDC updates on Johnson & Johnson’s Janssen (J&J/Janssen) COVID-19 Vaccine
What does a pause mean?
On April 13, 2021, CDC and the US Food and Drug Administration (FDA) recommended a pause in the use of Johnson & Johnson’s Janssen (J&J/Janssen) COVID-19 Vaccine. Although the J&J/Janssen vaccine is still authorized for use, CDC and FDA recommend this vaccine not be given to anyone until we know more. This gives scientists a chance to review the data and decide if recommendations on who should get the vaccine need to change. CDC and FDA will share more information as soon as possible with healthcare providers, people who got the vaccine, and the public.
What do I need to know about possible safety issue?
Here is what we know now: scientists and doctors always look carefully at all reported side effects.
From their review, they saw a small number of cases of a rare and severe type of blood clot in people who got the J&J/Janssen COVID-19 Vaccine. All reported cases were in women between the ages of 18 and 48, and the problems were found up to two weeks after vaccination.
What if I got this vaccine?
- If you got this vaccine more than three weeks ago, your risk of developing a blood clot is very low.
- If you got this vaccine within the last three weeks, your risk of developing a blood clot is also very low. However, you should be on the lookout for possible symptoms of a blood clot: severe headache, blurred vision, fainting, seizures, pain in your abdomen (chest or stomach), leg pain or swelling, shortness of breath.
