New clinical trials show that both mRNA COVID-19 vaccines are safe for pregnant women and may even pass some immunity on to their newborns.

Two NIH supported studies on the effects of the Pfizer and the Moderna vaccines on pregnant and breastfeeding women have completed. They found that the women gained immunity with minimal side effects (the most common was a short-lived fever).

The vaccines may also transfer some immunity to both fetuses and newborns.

During clinical trials there was no damage to the placenta of any women in the studies. There have also been no reports of any harm to pregnant women or their babies on the FDA and CDC’s safety monitoring systems.

Neither vaccine shows any sign of causing miscarriage or infertility.

Pregnant women are at higher risk for severe illness from COVID-19.

According to the CDC, “Pregnant people with COVID-19 are at increased risk of preterm birth and might be at increased risk of other adverse pregnancy outcomes compared with pregnant women without COVID-19.”

Therefore the CDC suggests that pregnant women get vaccinated. Because data is limited, both the FDA and CDC suggest talking to your doctor about the risks and benefits of getting vaccinated while pregnant.
