HealthDay News reports the study “found that antibodies to the [COVID] virus in nearly 1,400 women and their babies at the time of delivery didn’t vary dramatically based on when a woman got her vaccine during pregnancy.”
“Women often ask what is the best vaccination timing for the baby — our data suggest that it’s now,” study co-author Dr. Malavika Prabhu said in a news release from Weill Cornell Medicine. She is an assistant professor and ob-gyn at New York-Presbyterian/Weill Cornell Medical Center in New York City.
For the study, researchers at the two institutions measured antibody levels in the mothers’ blood and the babies’ umbilical cord blood. While levels were higher when vaccination occurred in a woman’s third trimester, they were comparably high and likely protective when vaccination happened early in pregnancy or even a few weeks before, the study found. Furthermore, a booster shot late in pregnancy can also make those antibody levels much higher, researchers said.
The researchers concluded that “expectant mothers should not delay COVID-19 vaccination until late pregnancy.”
“The message here is that you can get vaccinated at any point during pregnancy and it is likely going to be beneficial to you and your baby at the time of birth — and of course, by getting vaccinated early you will be protecting yourself and your baby throughout the pregnancy,” said first author Dr. Yawei Jenny Yang, an assistant professor of pathology and laboratory medicine at Weill Cornell.
“These study results are consistent with what we see with other maternal vaccines such as flu and Tdap, which, when given during pregnancy, protect the mother and baby,” said senior author Dr. Laura Riley, chair of the Department of Obstetrics and Gynecology at Weill Cornell Medicine and obstetrician and gynecologist-in-chief at NewYork-Presbyterian/Weill Cornell Medical Center.
In a related story, the New York Times reports “women who received COVID vaccinations while pregnant were at no greater risk of” preterm births or small-for-gestational-age births, according to a CDC study that looked at over 46,000 pregnancies that resulted in a live birth and included over 10,000 women who received one or more doses of COVID vaccine during their pregnancies between Dec. 15, 2020, and July 22, 2021.
