DART research are carried out in animals to evaluate the potential dangers related to a vaccine to a growing fetus.

“Pfizer recognizes that developing a potential SARS-CoV-2 vaccine for broad use is critically important to help stop the pandemic, including for potential use in pregnant women,” Pitts mentioned in an announcement. “Pfizer is in the process of conducting DART studies and plans to submit available data to the agency.”

Pfizer acknowledged on the FDA’s vaccine assembly Thursday that it is lacking data on the vaccine’s have an effect on on pregnant women, in accordance with a slide presentation. Representatives for the corporate advised the advisory committee that it expects preliminary outcomes from its DART research by mid-December.

The firm additionally famous that it is also lacking data on the results of the vaccine in kids and teenagers underneath 16. The FDA’s advisory committee will vote on its non-binding advice later Thursday and the FDA is anticipated to quickly.
