A pregnant US health worker who was vaccinated against COVID-19 has passed those antibodies to her newborn baby, according to doctors.
It’s the first-known case and a potentially important step in the fight against the coronavirus pandemic, WPBF reports.
“To our knowledge, this was the first in the world that was reported of a baby being born with antibodies after a vaccination,” said Florida paediatrician Paul Gilbert.

The mother was a frontline health worker who was 36 weeks pregnant when she received the first dose of the Moderna vaccine.
Three weeks later towards the end of January she gave birth to a girl and a blood sample was taken.
“We tested … the baby’s blood, to see if the antibodies in the mother passed to the baby which is something we see happen with other vaccines given during pregnancy,” Dr Gilbert said.
The results revealed the newborn had COVID-19 antibodies.
“To our knowledge, this was the first in the world that was reported of a baby being born with antibodies after a vaccination.”
Mr Gilbert and another Florida doctor, Dr Chad Rudnick, have collated their findings in an online journal, medRxiv. It has yet to be peer reviewed.

“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,” Dr Rudnick said.
But the Florida medics said there are other factors that indicate babies born to vaccinated mothers remain at risk from coronavirus.
“Further studies have to determine how long this protection will last,” said Dr Rudnick.
“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.”
Vaccinated pregnant women have started to be included in studies by some pharmaceutical companies.
