A new peer-reviewed study has confirmed that the spike protein from Covid mRNA “vaccines” has been found in the brains of almost half of “vaccinated” women who suffered strokes, long after they received their last injection.
The spike was detected in vital organs of the victims up to 17 months after the “vaccine” was administered, the study found.
The study, conducted by leading Japanese scientists, confirmed that the spike protein detected had originated from the mRNA “vaccines” in all of the patients.
None of the patients had an active COVID-19 infection at the time of their stroke.
The results of the study were published in the June edition of the Journal of Clinical Neuroscience.
The team of ten researchers was led by Dr. Nakao Ota of the Department of Neurosurgery’s Stroke Center at the Sapporo Teishinkai Hospital in Japan.
The study retrospectively examined the cases of 19 hemorrhagic stroke victims from 2023 and 2024.
They sought to investigate the potential link between the strokes and Covid mRNA “vaccines.”
Spike protein was found in the tissue and organs of 43.8% of the 19 stroke victims examined.
All the patients in the 43.8% group were women.
Researchers found the spike protein inside the cerebral arteries, which flow to the brain.
In one patient, spike protein was present 17 months after vaccination.
In two others, the spike was detected 12 and 11 months following vaccination, respectively.
The researchers said the findings “raise significant concerns” about the long-term safety of the mRNA “vaccines.”
They cited the role of lipid nanoparticles, which deliver mRNA to human cells.
The scientists explain that this is contributing to the risk of stroke.
“These findings raise significant concerns regarding the biodistribution of lipid nanoparticle-based vaccines and their long-term safety,” the researchers wrote.
Other studies have found that lipid nanoparticles deliver DNA contaminants, contained within mRNA “vaccines,” throughout the body.
The study results also contradict claims that the spike protein’s presence in the body would remain localized to the vaccination site and last only for a brief period.
The U.S. Centers for Disease Control and Prevention (CDC) claims that after mRNA enters muscle cells following COVID-19 vaccination, the cells’ machinery is used “to produce a harmless piece of what is called the spike protein.”
The protein’s presence then “triggers our immune system to produce antibodies and activate other immune cells to fight off what it thinks is an infection.”
“Any side effects from getting the vaccine are normal signs the body is building protection,” the CDC claims.
Responding to the study, Christof Plothe, D.O., a member of the World Council for Health steering committee, warned that the prolonged presence of spike protein “raises serious questions about the long-term behavior of mRNA technology in the human body.”
“While the study does not definitively prove causation, the detection of spike protein in brain arteries — combined with signs of immune cell infiltration — suggest a plausible mechanism for blood vessel damage and hemorrhagic strokes,” Plothe said.
According to the study, clinical trials for the Covid mRNA “vaccines” demonstrated their “short-term safety and efficacy.”
However, the long-term effects and biodistribution of the vaccines “remain underexplored.”
Plothe said the lack of long-term safety data for the mRNA COVID-19 vaccines is “troubling.”
He argues that the accelerated approval process for these “left critical gaps in our understanding of these vaccines’ delayed effects.”
Despite a lack of long-term safety data, what we do know about the effects of spike proteins on the body is troubling, Plothe said.
“The potential consequences of lingering spike protein are severe and multifaceted,” Plothe said.
“Chronic inflammation, clotting disorders, and autoimmune reactions could emerge over time, posing risks that were never adequately assessed during clinical trials.”
He added that multiple studies and autopsy reports have shown that mRNA vaccines can cause vascular and neurological damage.
Renowned McCullough Foundation epidemiologist Nicolas Hulscher also responded to the latest Japanese study.
Writing on Substack, he referenced a recent study in Nature Biotechnology.
The Nature study, conducted by a large group of Chinese researchers, found that mRNA vaccination in mice resulted in spike protein expression “in critical organs, including the liver, spleen, lungs, heart, head, and kidneys.”
“Unfortunately, this appears to also be the case in humans,” Hulscher wrote.
In November 2024, another peer-reviewed study published in the International Journal of Innovative Research in Medical Science found that Covid mRNA vaccines pose a 112,000% greater risk of brain clots and strokes than flu vaccines.
The Covid injections also cause a 20,700% greater risk of those symptoms than all other vaccines combined.
In February, Yale University researchers published a preprint showing that spike protein from the Covid mRNA vaccines was detected in the blood of at least one person 709 days after vaccination.
This is a significantly longer time than previously measured.
In addition, a study published last month in Immunity, Inflammation and Disease found that young adults who received a Pfizer mRNA “vaccine” showed elevated spike protein production a year or more after vaccination.
According to the authors of the new study, “Global replication studies are urgently required to validate these findings and ensure comprehensive safety evaluations of mRNA vaccines.”
Plothe said the new study adds to “a growing body of evidence” of harm caused by mRNA vaccines.
The findings contribute to calls for their suspension or withdrawal, he noted.
“Given the unresolved safety concerns and the availability of alternative solutions, a global moratorium on these vaccines is urgently needed,” Plothe said.
“Independent, transparent research must take precedence to determine whether the risks outweigh any purported benefits — before more lives are irrevocably harmed.”
