A woman in the state of Florida that received one dose of the COVID-19 vaccine while she was pregnant, passed antibodies to her newborn, according to Fox News.
The baby is believed to be the first newborn with coronavirus antibodies.
“To our knowledge, this was the first in the world that was reported of a baby being born with antibodies after a vaccination,” pediatrician Paul Gilbert said.
The woman, who is a front-line health worker was 36 months pregnant at the time she was inoculated with her first dose of the Moderna vaccine.
After the baby was born a blood sample was taken from the newborn to see if it carried the antibodies.
Gilbert said, “We see happen with other vaccines given during pregnancy.”
“This is one small case in what will be thousands and thousands of babies born to mothers who have been vaccinated over the next several months,” said Chad Rudnick.
The mother received her second dose of the Moderna vaccine post-partum.
Researchers warned that the babies still run a risk for infection if the mother was inoculated while pregnant.
“They have to determine at what level of protection or how many antibodies does a baby need to have circulating in order to give them protection,” Rudnick said.

A separate study published last month in the journal JAMA Internal Medicine suggests that those who have COVID-19 antibodies have a significantly lower risk of reinfection compared to those who do not have them.
The study also suggests that those who have coronavirus antibodies may be protected from reinfection up to 90 days, or about three months, and possibly beyond.
Rudnick, however, noted that further studies are needed to determine how long the protection will last.
