What You Need to Know About COVID-19 and COVID-19 Vaccines

Disclaimer: This page houses important COVID-19 information. Resources pertain to COVID-19 and COVID-19 vaccines during pregnancy and while breastfeeding, including links to our evidence-based Fact Sheets. However, the resources here should not replace the care and advice of a medical professional.

COVID-19 is a respiratory illness caused by the SARS-CoV-2 virus. Studies show that women who are pregnant and get COVID-19 have a higher chance of becoming very sick than women who are not pregnant. Having a COVID-19 infection in pregnancy also increases the chances of certain pregnancy complications. Major medical organizations recommend that women who are planning pregnancy, currently pregnant, recently pregnant, and/or breastfeeding stay up to date with the latest COVID-19 vaccine. Studies that have included thousands of women who were vaccinated during pregnancy do not find a higher chance of miscarriage, birth defects, or pregnancy complications. Lactation studies have found that the vaccine does not cause problems for breastfeeding infants. Staying up to date with COVID-19 vaccines is the best way to protect yourself against COVID-19.

Join Our COVID-19 Study

MotherToBaby is currently conducting a study looking at Paxlovid used to treat COVID-19 in pregnancy. If you’re pregnant, have or had a known COVID-19 infection during pregnancy, and you are or were being treated with Paxlovid, please consider enrolling into our observational study to give parents-to-be better answers about COVID-19 and the medications used to treat it during pregnancy. You will not be asked to take or change any medications, and you can participate from the comfort of your home. For more information, download our study flyer for participants (English & Spanish) or for healthcare providers.

Please see our library of COVID-19 information resources below on exposures and vaccines during pregnancy and breastfeeding.
