Pregnant women who get the COVID-19 vaccine are less likely to have a preterm birth, a new study says.

Vaccination was also strongly associated with lower risk of hospitalization or intensive care treatment among expecting mothers, researchers reported Monday in the Journal of the American Medical Association.

"Our findings provide clear, population-level evidence that COVID-19 vaccination protects pregnant people and their babies from serious complications," said senior researcher Dr. Deborah Money, a professor of obstetrics and gynecology at the University of British Columbia in Canada.

"Even as the virus evolved, vaccination continued to offer substantial benefits for both mother and child," Money said in a news release.
