Did you receive a COVID-19 mRNA vaccine in the last 2 months?

Join our COVID-19 vaccine study!

MotherToBaby is currently enrolling pregnant people who received a COVID-19 mRNA vaccine (Pfizer-BioNTech or Moderna) in the last 2 months for an observational study. The study aims to learn more about COVID-19 vaccines during pregnancy.

The study involves:

  • 1-3 phone interviews during your pregnancy and at least 1 interview after you have your baby.
  • Providing a blood sample at a lab near you. We will use this to study how your immune system responds to the vaccine.
  • Your permission to obtain a copy of your and your baby’s medical records from your healthcare providers.
