COVID-19 vaccines safe and effective for pregnant women, experts say

The antibodies from COVID vaccines that a mother receives will pass into the breast milk, as well as her circulation, and the baby will be protected.

LANE COUNTY, Ore. -- Across Oregon, pregnant people over the age of 16 became eligible for a COVID-19 vaccine on Monday, falling under Phase 1B Group 6.

In many counties, vaccinations began last week for that population after a green light was given from the state for early vaccinations to begin.


Many pregnant women have wondered if getting a COVID-19 vaccine will have any type of negative impact on their pregnancy and specifically the health of the baby.

Dr. Patrick Luedtke with Lane County Public Health said there is good news. The antibodies from COVID-19 vaccines that a mother receives will pass into the breast milk, as well as her circulation, and the baby will be protected.

“The mom is providing the food to the fetus while the fetus is inside,” Luedkte said. “So the fetus gets those antibodies too. It's reasonable to assume those antibodies will last four to six months after delivery, but we don't have all that data yet.”

New research was published Thursday in the American Journal of Obstetrics and Gynecology saying that the Moderna and Pfizer vaccines are effective in pregnant and lactating women.

“The data we have so far is really comforting,” Luedtke said. “No major red flags of any kind and not even a slight signal in the noise that there are problems out there."

Luedtke said to talk to your Family Practice doctor or OB-GYN if you have questions or concerns about your specific pregnancy.

“They have all those test results," Luedtke said. "When a woman first gets pregnant, they have a million blood tests run, and all those test results are meaningful. They're important, and they have to be interpreted. It's really best for that patient to speak with their doctor to get the latest data.”

The Centers for Disease Control and Prevention has a registry that shows more than 60,000 people have become pregnant or were pregnant when they got vaccinated.
