J&J Vaccine FAQ
Q. How does the viral vector vaccine work?
A. Viral vectors use a modified version from a different virus to deliver information to cells. The viral vector COVID-19 vaccine uses a different, harmless virus to enter cells in the body in order to produce the spike protein of the COVID-19 virus. This spike protein is harmless
Similar to the mRNA vaccines effects, our cells present the spike protein on its surface so that our immune system recognizes this foreign protein and can start producing antibodies against it
Q. Can I get the vaccine if I’m pregnant or breastfeeding?
A. There is currently insufficient data to determine whether there are vaccine-associated risks in those who are pregnant or breastfeeding.
However, the CDC states that if you are pregnant you may choose to be vaccinated as there is no evidence that the antibodies formed from COVID-19 vaccination can cause any problem with pregnancy. The CDC is continually updating its guidance on COVID-19 vaccination
Q: Are there any contraindications to the vaccine?
A. Individuals with a known history of severe allergic reaction to any components of the Janssen COVID-19 vaccine are contraindicated
Q: Can the Janssen COVID-19 vaccine be used to complete a vaccination series initiated with another COVID-19 vaccine?
A. There is no data available regarding the use of the Janssen COVID-19 vaccine to complete another vaccination series
Q: Can the Janssen COVID-19 vaccine be administered at or around the same time as other vaccines?
A. There is currently no data available regarding the use of this vaccine with other vaccines
