- The most common side effects seen with the J&J COVID-19 vaccine are pain at the injection site, headache, and flu-like symptoms.
- There have been fewer cases of allergic reactions to the J&J vaccine compared with the Moderna-NIAID and Pfizer-BioNTech vaccines.
- The FDA will continue to monitor the safety of the J&J vaccine as it’s rolled out to the American public.
In February 2020, the Food and Drug Administration (FDA) issued an emergency approval for the one-dose COVID-19 vaccine developed by Johnson & Johnson’s subsidiary company Janssen Biotech.
As with the two mRNA vaccines approved in December, the J&J vaccine has mostly mild side effects that can be managed with rest or an over-the-counter pain reliever.
So far, there have been fewer cases of allergic reactions to the J&J vaccine compared with the Moderna-NIAID and Pfizer-BioNTech vaccines, although J&J reported in February that two clinical trial participants had a severe allergic reaction after receiving its vaccine.
The FDA will continue to monitor the safety of the J&J vaccine as it’s rolled out to the American public.
