COVID Vaccine mRNA Can ‘Spread Systemically’ to Placenta and Infants of Women Vaccinated During Pregnancy

A new report suggests vaccine mRNA does not remain at the injection site following vaccination but can “spread systemically” to the placenta and umbilical cord blood of infants whose mothers are vaccinated during pregnancy.

Researchers vaccinated two pregnant women with mRNA vaccines shortly before delivery to determine whether the mRNA in COVID-19 vaccines reached the placenta or fetus following maternal vaccination.

“The primary objective of the study was to investigate the knowledge gaps surrounding mRNA therapies during pregnancy, utilizing the COVID-19 vaccine as a foundation for future mRNA therapeutic developments, given its established use,” the study’s corresponding author, Dr. Nazeeh Hanna, a neonatologist, told The Epoch Times by email.

Researchers Find Vaccine mRNA in Samples

The first patient, “Patient 1,” was a 34-year-old woman at 38 weeks and four days gestation who received two Pfizer vaccine doses and two booster doses—one Pfizer and one Moderna. The Moderna booster dose was administered two days before the delivery of a healthy baby by cesarean section.

The second patient, “Patient 2,” was a 33-year-old woman at 40 weeks gestation. She received two Pfizer vaccine doses. The last dose was given 10 days before vaginal delivery of a healthy baby.

Researchers also detected a “notably high signal” of vaccine mRNA in the placental decidua tissue of Patient 1, who received four vaccine doses. The decidua is the specialized endometrium layer that forms the base of the placental bed.

Spike protein expression was also detected—but only in the placenta of Patient 2. However, vaccine mRNA was detected in Patient 1’s cord and maternal blood samples, which were unavailable for the second patient.

The authors said the expression of spike protein in the placenta of the second patient but not in the first suggests that more than two days are necessary following vaccination for the mRNA to reach the placenta and be translated into the spike protein, which is then expressed in placental tissue.

Finally, researchers found the integrity of vaccine mRNA varied across different samples—the vaccine’s ability to activate an immune response relies upon fully intact mRNA. According to the findings, vaccine mRNA was largely fragmented in the cord blood and less fragmented in the placenta. In the placentas, 23 percent and 42 percent of the initial integrity was retained in Patients 1 and 2, respectively. In maternal blood from Patient 1, the vaccine’s mRNA had a high level of integrity at 85 percent. Integrity decreased to 13 percent in cord blood, suggesting limited bioactivity.

COVID-19 mRNA vaccines use lipid nanoparticles (LNPs) to deliver mRNA. “The findings suggest that lipid nanoparticles (LNPs) are capable of reaching the placenta and releasing mRNA within placental cells, where it is then translated into the spike (S) protein. However, by the time the mRNA reaches the fetus, it is no longer encapsulated by the LNPs, leading to its degradation (only 13% of the mRNA is intact in fetal circulation),” Dr. Hanna told The Epoch Times.

Dr. Hanna noted that the authors of the recently published paper did not evaluate the implications of transient spike protein expression in the placenta or the effects of degraded mRNA on the fetus.

“There have also been VAERS [Vaccine Adverse Event Reporting System] reports of infants dying of thrombocytopenia (low platelets) following maternal vaccination, and also evidence of infants having heart attacks in the womb following maternal vaccination. None of this is new information. It has simply been widely and systematically censored,” she added.

Dr. Dan McDyer, an obstetrician-gynecologist, told The Epoch Times in an email that he is not surprised by the “discovery of evidence of mRNA from the SARS CoV-2 injections and/or SARS CoV-2 spike protein present in fetal cord blood and placental tissues.”

“To me, the recommendation of administering this medication to pregnant women was one of the most irresponsible actions in the history of modern medicine. I am so disappointed that the entities charged with the mission of protecting public health (FDA) and women’s health (ACOG) were derelict in their duties because it only took me about 15 minutes of online research to determine that these lipid nanoparticles were going to cross the placenta and infect the fetus,” Dr. McDyer said.

Dr. James Thorp, a board-certified obstetrician-gynecologist and maternal-fetal medicine physician, told The Epoch Times by email that the paper shows mRNA from both Pfizer and Moderna vaccines can cross the placenta into the fetal blood entering the placental tissue.

“These authors observed a ‘notably high signal’ in the decidua, which is the lining of the uterus. This concentrated mRNA in the decidual tissues will be translated into high concentrations of spike protein, likely contributing to a myriad of devastating effects on human reproductive function—not just severe abnormalities of menstrual periods, but infertility, multiple pregnancy complications, and severe bleeding in pregnancy and in the post-partum period,” Dr. Thorp said.

Two previous human studies by the same researchers assessed whether the mRNA in COVID-19 vaccines is present in the placenta following maternal vaccination using different methods. The first study failed to detect mRNA in maternal and cord blood or placental tissue. The researchers attributed this to the long interval between vaccination and delivery and the methodology used in the study. The second study using improved sensitivity to detect mRNA also did not reveal vaccine mRNA. However, the authors attributed this to the probe that targeted the SARS-CoV-2 gene rather than the vaccine mRNA sequence.

In the current study, the authors used a more sensitive and robust approach which allowed them to have a more precise quantification of vaccine mRNA for superior accuracy, and a probe tailored explicitly for the vaccine mRNA, ensuring more reliable detection.

“Imagine this: The fetal immune system ‘learns’ the appearance of ‘self’ early on by recognizing molecules, MHCs (Major Histocompatibility Complexes), on the surface of all of our cells. This appearance of ‘self’ is most certainly disrupted by the appearance of spike protein on the surface of these cells (cell membranes) as induced by the ‘vaccines,’’’ he told The Epoch Times.

“Additionally, fragments of spike protein will also likely appear in the MHCs on the cell surfaces. This causes a slight disfigurement of these MHCs which is likely to have an effect on the immune system’s capability to recognize ‘self,’” he added.

Dr. McDyer said he is certain disrupting cellular homeostasis by distracting the fetal cells to produce foreign proteins, such as the spike protein, instead of the proteins necessary for a developing fetus, will have detrimental unknown consequences. He believes this explains why one of his colleagues, a pediatric neurosurgeon, has seen a few unborn babies who have had strokes, an event he says he has never heard of in his entire career until now.
