Pregnant women have been systematically overlooked in the development and deployment of new vaccines, undermining their health and their communities’ safety, according to guidelines released this month by an international team of researchers, scientists and health care providers.
The report, developed by the Pregnancy Research Ethics for Vaccines, Epidemics and New Technologies (PREVENT) working group, identifies a cycle of exclusion that prevents pregnant women from accessing the benefits of vaccines.
“There’s a lot of reticence to include pregnant women in research,” said Carleigh Krubiner, the project director and a co-principal investigator for PREVENT.
And that’s led to a shortfall in data about how pregnant women respond to vaccines.
Krubiner, an associate faculty member at the Johns Hopkins Berman Institute of Bioethics, told VOA that researchers and health care providers tend to exclude pregnant women from trials, vaccinations and tracking because they lack evidence of the risks expectant mothers face.
“We continue to have this Catch-22 of not having enough evidence to feel like we can do the research. But if we don’t do the research, we don’t have the evidence,” Krubiner said.
