In an important development, Pfizer and BioNTech have commenced clinical trials of their COVID-19 vaccine involving pregnant individuals, marking a first in the United States. This announcement comes after a period of uncertainty where organizations like the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) offered conflicting guidance on the vaccine’s suitability for expectant mothers.
The international study aims to recruit around 4,000 participants across several countries, including the U.S., Canada, and parts of South America and Europe. Participants will be women aged 18 and older who are pregnant. The vaccination process will take place between weeks 24 and 34 of pregnancy, with two doses administered 21 days apart, mirroring the methodology used in larger trials.
This study is particularly significant as it will assess the vaccine’s safety and efficacy for pregnant individuals, especially given that they face a higher risk of severe respiratory complications from COVID-19. Dr. Samuel Carter, a senior researcher at Pfizer, expressed pride in advancing this research, emphasizing the importance of gathering data to support vaccination in this vulnerable group.
The initiative also aligns with the NIH’s recent advocacy for increased inclusion of pregnant and lactating individuals in vaccine research. The CDC has reiterated that current evidence suggests mRNA vaccines, like those developed by Pfizer and BioNTech, are likely safe for both the pregnant individual and the fetus.
After receiving the vaccine, participants will be observed for six months post-delivery to monitor the transfer of antibodies from mother to baby. Other pharmaceutical companies such as AstraZeneca and Johnson & Johnson are expected to follow suit with their own trials focused on pregnant individuals.
