Pfizer and its partner company said this week that they’re launching a clinical trial to see if their COVID-19 vaccine is safe and effective for pregnant women.
The phase 2/3 study will test approximately 4,000 healthy, pregnant women 18 years of age or older, according to Pfizer and BioNTech. The women will get the shot between 24 to 34 weeks of gestation in the randomized, placebo-controlled, observer-blind trial.
