The safety and well-being of the people who use our products is our number one priority.
Rare cases of the neurological disorder, Guillain-Barré syndrome have been reported following vaccination with the Janssen COVID-19 vaccine. Most occurred within 42 days after vaccination. While the chance of having this occur is very low, Johnson & Johnson has updated its COVID-19 Vaccine Factsheet to include important information about these rare cases and on the signs and symptoms of Guillain-Barré syndrome. Updates with this new information will be implemented in other regions of the world according to local regulatory procedures.
Any adverse event report about individuals receiving Johnson & Johnson’s single-shot COVID-19 vaccine, as well as our own assessment of the report, is shared with the U.S. Food and Drug Administration, the European Medicines Agency, the World Health Organization and other health authorities around the world where our vaccine is authorized. We strongly support raising awareness of the signs and symptoms of rare events to ensure they can be quickly identified and effectively treated.
Evidence has demonstrated that Johnson & Johnson’s single-shot COVID-19 vaccine offers protection against COVID-19 disease and prevents hospitalization and death, including in countries where viral variants are highly prevalent. A single-shot vaccine that provides this level of protection represents an important tool in the global fight against COVID-19, as we strive to help end this deadly pandemic.

What Is the Janssen COVID-19 Vaccine?
The Janssen COVID-19 Vaccine is an unapproved vaccine that may prevent COVID-19. There is no FDA-approved vaccine to prevent COVID-19.
The FDA has authorized the emergency use of the Janssen COVID-19 Vaccine to prevent COVID-19 in individuals 18 years of age and older under an Emergency Use Authorization (EUA).

Severe Allergic Reactions
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:

Blood Clots with Low Levels of Platelets
Blood clots involving blood vessels in the brain, lungs, 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 one to two-weeks following vaccination. Reporting of these blood clots and low levels of platelets has been highest in 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 or 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.
