mRNA From COVID-19 Vaccine Found in Breastmilk, New Study Shows

A new study shows that trace amounts of mRNA vaccines were detected in the breastmilk of women who participated.

The study published in the Journal of the American Medical Association (JAMA) found mRNA “detected in 7 samples from 5 different participants at various times up to 45 hours post vaccination.”

Participants included 11 lactating women, six who received the Pfizer treatment and five who received the Moderna treatment.

This latest data contradicts information JAMA published in July 2021 when researchers assured the public that no mRNA was being found in breastmilk.

At the time, researchers said there was “evidence to strengthen current recommendations that vaccine-related mRNA is not transferred to the infant and that lactating individuals who receive the COVID-19 mRNA-based vaccine should not stop breastfeeding.”

In analyzing the most recent data, however, researchers warn “caution is warranted about breastfeeding children younger than 6 months in the first 48 hours after maternal vaccination until more safety studies are conducted.”

Congressman Thomas Massie (R-Ky.) shared the new information on Twitter, saying: “Now we find out that Biden’s vaccine mandates caused infants (for which no safe dose has been established) to receive mRNA through their mother’s breast milk. Does abuse of power get any more evil?”

Doctors who conducted the research also noted that 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” by vaccinated women who plan to breastfeed.

"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," doctors said. "It is critical that lactating individuals be included in future vaccination trials to better evaluate the effect of mRNA vaccines on lactation outcomes."

The study also noted that the presence of mRNA was not detected in samples that were collected 48 hours post-vaccination.

Data from the study show a large disparity in the concentration of mRNA found in the samples, but the authors did not explain what concentration level should be concerning.
