Name: Janssen COVID-19 Vaccine
For which conditions is Janssen COVID-19 Vaccine used? The U.S. Food and Drug Administration (FDA) has issued an Emergency Use Authorization (EUA) for the Janssen COVID-19 Vaccine for immunization to prevent COVID-19 in individuals 18 and older. The EAU permits the emergency use of the vaccine although it has not been FDA approved. There are currently no FDA approved vaccines to prevent COVID-19.
What is the mechanism of action? The Janssen COVID-19 Vaccine is a viral vector vaccine that works by using a harmless adenovirus that has been engineered to carry genetic code (DNA) to initiate the body to create a protein from the virus which then promotes an immune system response to recognize the virus and learn to attack the virus.
How is the Janssen COVID-19 Vaccine typically given (administered)? Janssen COVID-19 Vaccine is an intramuscular injection given in one dose. There is no data to support interchangeability of this vaccine with other COVID-19 vaccines to complete a vaccination series started with another COVID-19 vaccine.
How are patients typically monitored? Patients will be monitored for immediate allergic reactions after receiving the Janssen COVID-19 Vaccine.
What side effects have been reported? Side effects that have been reported include the following:
- Injection site pain
- Muscle pain
- Injection site redness
- Injection site swelling
It is important to report side effects to your healthcare provider. Some patients may experience other side effects that are not listed here and additional side effects may become apparent with more widespread use of the Janssen COVID-19 Vaccine.
What can patients do to help alleviate or prevent discomfort and side effects?
- If you have a history of severe allergic reaction to any component of the Janssen COVID-19 Vaccine, tell your healthcare provider and do not receive the vaccine. Components of the Janssen COVID-19 Vaccine include virus particles, citric acid monohydrate, trisodium citrate dihydrate, ethanal, HBCD, polysorbate-80, sodium chloride and residual host cell proteins.
Are there any special precautions patients should be aware of before receiving the Janssen COVID-19 Vaccine?
- Tell your vaccination provider if any of the following apply to you: Have any allergies Have a fever Have a bleeding disorder or are on a blood thinner Are immunocompromised Are on a medicine that affects your immune system Are pregnant or plan to become pregnant Are breastfeeding Have received another COVID-19 vaccine
- Tell your healthcare provider if you have a history of a severe allergic reaction to any component of the Janssen COVID-19 Vaccine.
- Individuals who are immunocompromised, should be aware that they could have a diminished immune response to the vaccine.
- The Janssen COVID-19 Vaccine may not protect all vaccine recipients from contracting COVID-19.
- At this time, the vaccine-associated risks are unknown in individuals who are pregnant or breastfeeding.
- The EUA of the Janssen COVID-19 Vaccine does not include use in individuals younger than 18.
When should patients notify their physician?

You should also notify your physician of any side effects that bother you or do not go away.
