What are the ingredients in COVID-19 vaccines?

You may see some rumors and untrue ingredients listed online or in social media. These are generally myths. The ingredients in the COVID-19 vaccines are pretty typical for vaccines. They contain the active ingredient of mRNA or modified adenovirus along with other ingredients like fat, salts, and sugars that protect the active ingredient, help it work better in the body, and protect the vaccine during storage and transport.

See this Q&A webpage from the Children’s Hospital of Philadelphia for more information about ingredients. You can also find the full ingredients lists in the Pfizer, Moderna, and Johnson & Johnson fact sheets.
