 The Pfizer Maternal C-19 Vaccine Trial.


about the study

COVID-19 continues to spread around the world. One critical step in fighting this pandemic is learning about the safety and effectiveness of the study vaccine for all expectant mothers and their babies. Expectant mothers who enrol in this study will help us answer this question. By choosing to volunteer, you will represent expectant mothers like you - in age, race, ethnicity, and from communities like yours. You can help make a difference for other expectant mothers and babies.

A clinical trial is a type of research study that collects new information and answers doctors’ questions about health and disease. All new medicines and vaccines need to be tested in clinical trials before they can be available to the public. Most medicines are used to help people who are already sick. But vaccines are meant to keep people from getting sick. Developing a vaccine is a critical part in the fight against COVID-19. A local COVID-19 research study is comparing an investigational (study) vaccine against a placebo to see if the study vaccine can prevent COVID-19.



Women who are between 24-34 weeks pregnant.


Is this a live vaccine being studied?

The study vaccine does not contain any live virus. It cannot give clinical trial participants SARS-CoV-2 infection, nor can it give participants COVID-19. The placebo is also an injection but it contains saline instead of active vaccine.
