Two new studies show Pfizer and Moderna’s COVID-19 vaccines appear to be “completely safe” and effective for pregnant people, according to Dr. Francis Collins, director of the National Institutes of Health (NIH).

The vaccines were also found to likely offer protection as well to infants born to a vaccinated person, according to Collins.

“Overall, both studies show that COVID-19 mRNA vaccines are safe and effective in pregnancy, with the potential to benefit both mother and baby,” he wrote, later adding, “While pregnant women are urged to consult with their obstetrician about vaccination, growing evidence suggests that the best way for women during pregnancy or while breastfeeding to protect themselves and their families against COVID-19 is to roll up their sleeves and get either one of the mRNA vaccines now authorized for emergency use.”
