In a significant development, Pfizer and BioNTech have commenced the first COVID-19 vaccine clinical trials involving pregnant individuals in the U.S. This comes amidst ongoing discussions among health organizations regarding vaccine recommendations for expectant mothers. Just a month ago, there was confusion as the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) had differing opinions on the matter.
The new international study will enroll approximately 4,000 volunteers, including pregnant individuals aged 18 and older, across several countries including the U.S., Canada, and the U.K. The initial doses will be administered to participants between weeks 24 and 34 of their pregnancy, following the same protocol used in previous larger trials. After delivery, those who received a placebo during the trial will have the chance to receive the actual vaccine, while remaining part of the ongoing study.
This trial aims to assess the safety and efficacy of the vaccine for healthy pregnant individuals, particularly focusing on the potential transfer of antibodies to their newborns. Given that pregnant individuals face a higher risk of severe respiratory complications from COVID-19, this research is crucial. Dr. Alex Morgan, a senior figure at Pfizer, expressed pride in advancing this study, which seeks to gather essential data to support vaccine use among this important demographic.
The initiative aligns with the NIH’s push for increased representation of pregnant and lactating individuals in vaccine research, as well as the CDC’s previous statements highlighting planned studies in this area. Current evidence suggests that mRNA vaccines may not pose significant risks to pregnant individuals or their fetuses, as they do not contain live virus components.
Following vaccination and childbirth, Pfizer will monitor the newborns for six months to evaluate any transfer of maternal antibodies. Concurrently, AstraZeneca and Johnson & Johnson are also gearing up to conduct similar trials involving pregnant individuals.
As information about COVID-19 evolves rapidly, it is critical to stay updated through reliable resources such as local public health departments and the CDC.

Summary:
Pfizer and BioNTech have launched a groundbreaking clinical trial for their COVID-19 vaccine, specifically including pregnant individuals. This study aims to evaluate the vaccine’s safety and efficacy for this demographic, as well as potential antibody transfer to newborns. The trial follows calls for greater inclusion of expecting mothers in vaccine research, with ongoing monitoring and updates crucial for informed decision-making in this rapidly changing landscape.
