Pregnant Women Who Get Vaccinated Pass Protective Antibodies to Their Newborns


A new study out of NYU’s Grossman School of Medicine found that people who get vaccinated during pregnancy pass on high levels of protective antibodies to their babies, potentially protecting the newborns in their first months of life, when they’re most vulnerable.

Some highlights:

The study included 36 babies whose mothers had received either the Pfizer or Moderna vaccine during pregnancy, finding that 100% of the babies had protective antibodies at birth. According to one of the study’s lead researchers, that suggests the babies are protected during “the first several months of their lives, when they are most vulnerable.”

The researchers were also able to tell apart antibodies created from a mother’s natural infection and those from a vaccine, an important finding as natural infections don’t provide enough protection, according to the study.

Why it matters:

According to the most recent CDC data (from July), only 23% of pregnant people have received at least one dose of a vaccine, despite several studies finding the vaccines are safe and effective for them.

At the same time, a November 2020 CDC found pregnancy was associated with a 70% increased risk of death from COVID-19.
