Kailtin Bolan is a registered nurse at Fresenius, and is expecting her second son.

She said she did her research looking at the ingredients in the COVID-19 vaccines and what studies were done.

"I also talked to my OB, and we had a very lengthy conversation about it and that kind of drove me toward which way I wanted to go," Bolan said.

Bolan decided getting vaccinated was the right decision for her and her growing family, but she knows there's a lot of skepticism.

"I've actually had a few people reach out to me with concerns about the vaccine, like friends, and wondering if they should get it because they're either thinking about getting pregnant or they are pregnant," she said.

The World Health Organization is among those being skeptical, and doesn't recommend the vaccination of pregnant women due to insufficient data.

But other medical professionals, including Dr. Eva Pressman, say the vaccine gives pregnant women much-needed protection.

"It's very important to understand that this pandemic affects everybody, but it affects certain people more severely, and it turns out that one of the groups of people that had had worse outcomes is people during pregnancy," Dr. Pressman said.

Dr. Pressman is a maternal-fetal medicine specialist at St. Joseph's Health and chair of the Department of Obstetrics and Gynecology at the University of Rochester.

She's not aware of any pregnant women being negatively affected by the vaccine, but said studies that have come out so far show the coronavirus has been dangerous to pregnant women.

"During the first phases of this pandemic, pregnant women were more likely to have significant respiratory complications, were more likely to be admitted into the ICU to be intubated, and to die," said Dr. Pressman.

So far, Bolan said she's only had a sore arm since getting the vaccine.

"I actually didn't have any real symptoms after the vaccine, just a little arm soreness," Bolan said.

Dr. Pressman also encourages postpartum women who are breastfeeding, and women planning to conceive to get vaccinated if they can.
