Question: Do COVID-19 vaccines cause fertility or other reproductive issues?
: No. There is no evidence that any vaccines, including COVID-19 vaccines, can cause female or male fertility problems. There is no evidence that vaccine ingredients or antibodies developed following COVID-19 vaccination will cause any problems with becoming pregnant in the future. Similarly, there is no evidence that the COVID-19 vaccine affects puberty. Please visit the CDC webpage on COVID-19 vaccination and fertility to learn more
Question: Will getting a COVID-19 vaccine cause me to test positive on a viral test?
Answer: No. None of the authorized and recommended COVID-19 vaccines can cause you to test positive on viral tests, which are used to see if you have a current infection.
If your body develops an immune response to vaccination, which is the goal, you may test positive on some antibody tests. Antibody tests indicate you had a previous infection and that you may have some level of protection against the virus. Please visit the Return to Learn Vaccination Information webpage
to learn more about the vaccine.
Question: Are the ingredients in COVID-19 vaccines dangerous?
Answer: No. Nearly all the ingredients in COVID-19 vaccines are also ingredients in many foods – fats, sugars and salts.
Exact vaccine ingredients vary by manufacturer. Pfizer-BioNTech and Moderna COVID-19 vaccines also contain messenger RNA (mRNA) and the Johnson & Johnson/Janssen COVID-19 vaccine contains a harmless version of a virus unrelated to the virus that causes COVID-19. These give instructions to cells in your body to create an immune response. This response helps protect you from getting sick with COVID-19 in the future.
