According to a recent study published in The Lancet, mRNA from COVID-19 vaccines spreads “systemically” throughout the body, including in breast milk passed to infants by vaccinated mothers. This is not the first study to detect vaccine mRNA in breast milk. However, to date there are no questions about how it affects infants and whether they may experience the same health problems as those who have been directly vaccinated.
According to the study published in The Lancet in September, mRNA was found in the breast milk of 70 percent of women who provided samples up to 45 hours after vaccination. According to the researchers, more research is needed to determine the minimum amount of mRNA that triggers an immune response in newborns, although the mRNA found was largely fragmented and retained only 12 to 25 percent of its original integrity. I went. Thirteen lactating, healthy postpartum women were examined before vaccination and at least twice daily for five days after vaccination. After receiving the first and second doses of the vaccine, seven mothers donated breast milk, resulting in 154 breast milk samples and a total of 20 vaccine contacts.
Next, vaccine mRNA in whole milk and breast milk extracellular vesicles was analyzed. Extracellular vesicles (EVs) are small delivery systems secreted by cells that transport biomolecules such as messenger RNA, DNA, noncoding RNA, lipids, and proteins. EVs, which play important roles in regulating gene expression, immune response, infant growth and development, are abundant in breast milk. Among 13 breastfeeding women who received the Moderna or Pfizer vaccine, small amounts of mRNA were detected in 10 of 20 exposures up to 45 hours after vaccination. According to the study, the SARS-CoV-2 spike protein was not expressed.
Pre-vaccination samples and pre-test results for COVID-19 vaccine mRNA in breast milk samples from all participants were negative. The experiment was complicated by the fact that although all women were instructed to provide samples of 5 ml or more, the actual volume was often below the limit. “The model we used shows that after intramuscular administration, vaccine mRNA encapsulated in lipid nanoparticles is delivered to the mammary glands via hematogenous or lymphatic routes”The researchers wrote. “In the cytosol of breast cells, some of the released vaccine mRNA is recruited and packaged into developing extracellular vesicles, which are then released into breast milk.”
The researchers said the significance of their research goes beyond the scope of mRNA COVID-19 vaccines and “provides valuable insights into the transport and presence of vaccine mRNA in breast milk that will help assess the safety and effectiveness of future mRNA-based treatments.” Will give information.” may be relevant for women who are breastfeeding.” However, questions remain about what health effects absorption of mRNA particles through breast milk has on children. Politicians and the mainstream have long claimed that breastfeeding Vaccination is absolutely safe for expectant mothers and mRNA cannot be detected in breast milk – this statement was removed from a study a year ago (Report 24).
