The Pfizer/BioNTech and Moderna coronavirus vaccines don’t appear to pose any serious risks during pregnancy, a new study found.
The study, published Wednesday in the New England Journal of Medicine, showed the two mRNA-based vaccines are effective in pregnant and breastfeeding individuals, suggesting their benefits outweigh the risks, CNN reported.
More than 35,000 pregnant participants reported their health status through Centers for Disease Control and Prevention systems by way of smartphone app, and followed up with a group of pregnant people who had received an mRNA vaccine, CNN reported.
Adverse outcomes, including pregnancy loss and preterm births, were not significantly higher in individuals who had been given a vaccine, researchers found.
The study didn’t include the Johnson & Johnson or AstraZeneca vaccines, which aren’t based on the newer messenger RNA, or mRNA, technology, CNN reported.
