Whereas discovering lower-than-expected ranges of protecting antibodies in umbilical wire blood, researchers discovered excessive ranges of influenza antibodies, probably from maternal flu vaccination, based on the examine.
In different viruses or vaccines, antibodies are usually transferred at a lot greater ranges, probably for evolutionary causes as a result of infants cannot develop their very own antibodies till 6 months of age, Edlow stated.

The researchers hope to observe up with the ladies from this examine and their kids in future analysis.
“There could possibly be longer-term, extra refined neurodevelopmental results or different results on organ programming that might happen which might be separate from beginning defects or stillbirth or being born with COVID-19,” Edlow stated. “There are doubtlessly extra refined results that we’ll in all probability want years to tease out.”
