Vaccine-associated mRNA not detected in breast milk

Breastfeeding women have rightly wondered if they should continue to breastfeed after receiving the COVID vaccine. We have not known the answer to that question until now.

HealthDay reports, “Women who are breastfeeding and wonder if COVID-19 vaccination is safe for their baby may be reassured by the results of a new study.”

Researchers found “that ‘vaccine-associated mRNA’ – the active components of the Moderna and Pfizer vaccines – ‘was not detected in 13 milk samples collected 4 to 48 hours after vaccination from 7 breastfeeding individuals.’”

They also cautioned, “While a larger trial is needed to fully confirm the results, the researchers say their findings ‘provide important early evidence to strengthen current recommendations that vaccine-related mRNA is not transferred to the infant.”

So, the researchers add, “It appears that moms don’t have to choose between COVID vaccination and breastfeeding.”

The study was published in JAMA Pediatrics.
