Two obstetricians' groups are now recommending COVID-19 shots for all pregnant women, citing concerns over rising cases and low vaccination rates.
The American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine said vaccinations in tens of thousands of pregnant women have shown the shots are safe and effective.
COVID-19 during pregnancy increases risks for severe complications and can also increase chances for preterm birth.
U.S. data show only about 16% of pregnant women have received at least one COVID-19 vaccine dose.
The two groups had previously said pregnant women shouldn't be excluded from vaccination but stopped short of endorsing the shots.
