Pfizer and Moderna vaccines safe for pregnant women, study says

• Prior to this study, tens of thousands of pregnant women in the U.S. have already been vaccinated without complications.

Details: The study is the largest of its kind due to this group's initial exclusion of the vaccines' clinical trials.

• 131 women received either of the vaccines: 84 were pregnant, 31 were lactating and 16 weren't pregnant.
• Antibody levels following vaccination were the same in pregnant and lactating women compared to those who weren't pregnant, the study says.
• Results also showed that antibodies were passed on to newborns, based on levels measured in breast milk and the placenta.
