In research (Detection of SARS-CoV-2-Specific IgA in the Human Milk of COVID-19 Vaccinated Lactating Health Care Workers | Breastfeeding Medicine (liebertpub.com) from the University of Florida it was found that the breast milk of mothers vaccinated against COVID-19 contained a significant supply of antibodies that may help protect their nursing infants. This suggests that nursing mothers may be passing their immunity to their babies. The antibody level in breast milk from vaccinated mothers was higher than that found in breast milk from mothers who had natural immunity from the virus.
Babies are born with underdeveloped immune systems, making it hard for them to fight infections and they often are too young to respond adequately to certain types of vaccines. If the findings from this research hold, routine vaccination for mothers may be something we will see in the future.
