    • What are the ingredients in the Pfizer-BioNTech COVID-19 vaccine? The Pfizer BioNTech COVID-19 vaccine is a messenger RNA (mRNA) vaccine that has both synthetic, or chemically produced, components and enzymatically produced components from naturally occurring substances such as proteins.
    • Do mRNA vaccines change a person’s DNA? No, mRNA is a transient carrier of information that does not integrate into human DNA. [ii] Unlike a traditional vaccine that uses inactivated, dead, or portions of actual virus to spur an immune response, mRNA delivers a message to your body’s cells via a lipid nanoparticle envelope that instructs the cells to generate the spike protein found on the surface of a coronavirus that initiates infection.
    • Does your vaccine cause infertility? There are no data to suggest that the Pfizer-BioNTech COVID-19 vaccine causes infertility. It has been incorrectly suggested that COVID-19 vaccines will cause infertility because of a very short amino acid sequence in the spike protein of SARS-CoV-2 that is partly shared with a protein in the placenta called syncytin-1.
    • What about allergies and the Pfizer-BioNTech COVID-19 vaccine? In line with CDC recommendations, we did not test our vaccine in people with a history of severe adverse or allergic reactions to a vaccine or a vaccine ingredient.
