As the vaccination rollout continues, healthcare professionals are uncovering important insights regarding the immunity provided by COVID-19 vaccines. In a notable case from Florida, researchers have identified the first instance of a newborn exhibiting coronavirus antibodies after being born to a mother who had received only one dose of the vaccine, suggesting that maternal vaccination might confer some level of protection to infants.
The mother, a healthcare worker, received her initial dose of the Moderna vaccine in early January, just three weeks prior to giving birth. Notably, she had never contracted the virus, indicating that the antibodies detected in her baby were solely derived from the vaccine. The pediatricians, Dr. Emily Johnson and Dr. Mark Stevens from Boca Raton, collected a blood sample from the newborn and confirmed the presence of COVID antibodies. They are currently pursuing publication of their findings in a medical journal and hope to expand their research to include more mothers and their children.
It is well-established that mothers can transfer antibodies to their babies through the placenta, typically during the later stages of pregnancy. Although this passive immunity generally diminishes within weeks to months, it serves as a temporary shield for infants until they can receive their own vaccinations against various diseases like influenza and whooping cough. “We’ve seen similar patterns with other vaccines given to pregnant women,” Dr. Johnson explained. “Our hypothesis was that the COVID vaccine would yield similar results.”
Dr. Johnson and Dr. Stevens acknowledged that it remains uncertain how long the antibodies might persist in the baby or how effective they will be in preventing a COVID-19 infection. “More research is needed to ascertain the duration of this protection,” Dr. Stevens noted. “We also need to determine the antibody levels required for adequate protection in infants.”
With increasing numbers of pregnant women getting vaccinated against COVID-19, both doctors believe that such cases may become more frequent. “This is just one case among what will likely be thousands of babies born to vaccinated mothers in the coming months,” Dr. Stevens remarked.
