Detection of Messenger RNA COVID-19 Vaccines in Human Breast Milk
"...caution is warranted about breastfeeding children younger than 6 months in the first 48 hours after maternal vaccination until more safety studies are conducted."
Detection of Messenger RNA COVID-19 Vaccines in Human Breast Milk
“Of 11 lactating individuals enrolled, trace amounts of BNT162b2 and mRNA-1273 COVID-19 mRNA vaccines were detected in 7 samples from 5 different participants at various times up to 45 hours post vaccination”
“We believe it is safe to breastfeed after maternal COVID-19 vaccination. However, caution is warranted about breastfeeding children younger than 6 months in the first 48 hours after maternal vaccination until more safety studies are conducted. In addition, the potential interference of COVID-19 vaccine mRNA with the immune response to multiple routine vaccines given to infants during the first 6 months of age needs to be considered. It is critical that lactating individuals be included in future vaccination trials to better evaluate the effect of mRNA vaccines on lactation outcomes.”
Why would the CDC recommend vaccination for a baby who’s mother was vaccinated, without knowing how much of the vaccine has transferred to the baby in utero or via breastmilk?

COVID-19 vaccination is recommended for all people 6 months and older. This includes people who are pregnant, breastfeeding, trying to get pregnant now, or might become pregnant in the future. CDC also recommends COVID-19 vaccines for infants 6 months and older who’s mother was vaccinated or had a COVID infection before or while pregnant.
