Multifocal Necrotizing Encephalitis and Myocarditis After BNT162b2 mRNA Vaccination against COVID-19

A Summary (for the General Public) and Commentary Regarding the Case Report Published by Dr. Michael Mörz:

Multifocal Necrotizing Encephalitis and Myocarditis After BNT162b2 mRNA Vaccination against COVID-19


Above is the title page of an article written by Dr. Michael Mörz, a pathologist in Dresden, Germany.  Here is the link to the full article: (https://www.mdpi.com/2076-393X/10/10/1651). It is a case report of autopsy findings in a 76-year-old man who had died 3 weeks after receiving his third vaccination against COVID-19.  This case report was published by the peer-reviewed journal Vaccines on October 1, 2022 (Vaccines 2022, 10, 1651).

Dr. Mörz’s article provides compelling and sobering evidence of the potential of mRNA vaccines to cause serious harm to the brain and heart---namely, vasculitis, necrotizing encephalitis, and myocarditis.  His article may prove to be one of the most pivotal articles to be published in the formal conventional medical literature during the COVID-19 pandemic---because of its potential to change attitudes about the safety of mRNA vaccines against COVID-19.

To summarize the Mörz article, to present its pathology images in a way that might be more understandable to the general public, and to underscore the importance and implications of the article, I have written a Summary and Commentary about Dr. Mörz’ s article.

Take Home Visual images: 

The above image (from the Mörz article) shows a cross section of a capillary in the heart.  It demonstrates the presence of an abundant amount of spike protein (the brown material to which the red arrow points) within endothelial cells, which are the cells that line the inner wall of the capillary.  There is endothelial cell swelling, and there are a few mononuclear inflammatory cells within the wall of the capillary.  The spike protein was demonstrated to be of vaccinal origin, not from SARS-CoV-2 infection.

The above image (also from the Mörz article) is a cross section through a capillary in the brain.  It shows prominent signs of vasculitis (inflammation of the blood vessel wall). The vessel is filled with hemolyzed blood, which is normal in autopsied cases.  The many tiny blue cells that are present in the walls of the vessel (immediately surrounding the hemolyzed blood) include many lymphocytes (inflammatory cells).  The presence of numerous lymphocytes in the wall of this vessel means that the vessel wall is inflamed----i.e., the vessel is experiencing vasculitis. 

The importance of the Mörz article:

Dr. Mörz has conclusively demonstrated the presence of an abundance of vaccinal spike protein in the endothelial lining of the walls of capillaries and arterioles in the brain and heart.  He has also demonstrated significant inflammation within the walls of these same vessels.  His interpretations of the findings are accurate and not overstated.  He has appropriately suggested that these two findings are linked---that the inflammation in the vessel walls (vasculitis) was most likely triggered by the presence of vaccinal spike protein in those walls.  

Dr. Mörz has also conclusively demonstrated diffuse and multifocal inflammation in the brain tissue (encephalitis) and in heart muscle (myocarditis).  The encephalitis was necrotizing---i.e., associated with death (necrosis) of brain cells (neurons). 

The two images shown above (along with the several other images presented in the Mörz article) support the following hypothesis: When the mRNA (that is embedded in the lipid nanoparticle of the Pfizer/BioNTech COVID-19 vaccine) is injected into the arm, the mRNA finds its way (via the blood stream) into distant cells---in this case endothelial cells that line the small blood vessels in the heart and brain. (The vaccine does not simply stay in the arm.)  Once in the endothelial cell(s), the mRNA instructs the ribosomes in the cell to manufacture spike protein.  The spike protein then migrates to the outer surface of the endothelial cell.  The immune system then sees the spike protein (or fragments thereof) on the surface of the cell, recognizes it as foreign, and concludes that the endothelial cell has become infected.  Accordingly, the immune system sends lymphocytes and other inflammatory cells into the walls of the vessel to attack the presumed infected endothelial cell(s).  The vessel wall becomes inflamed (vasculitis) and, during this process, the endothelial cells become immunologically injured and may swell to varying degrees.  Sometimes, abnormal intravascular coagulation (clotting within the vessel) may be triggered.  In some instances spike protein finds its way through the blood vessel wall and penetrates into the brain (or heart) tissue, where the spike protein may trigger an inflammatory reaction in the brain (encephalitis) or heart (myocarditis).

People who have been vaccinated against COVID-19 (and those contemplating vaccination) deserve to know whether the Mörz report of probable vaccine-induced microvascular and parenchymal (tissue) injury in the brain and heart represent extremely rare phenomena or are more common than that.  Vaccinees and the public at large deserve to know the prevalence of such phenomena, and they deserve to know the full spectrum of such findings.  If such phenomena are more than rare, our hope would be that the abnormalities are usually only minimal, not as dramatic as in the case reported.  We would also hope that the abnormalities might be reversible, possibly amenable to treatment---particularly if patients are warned to not receive any further COVID-19 mRNA vaccination.

Scientific understanding of potential serious side effects of the mRNA vaccines---including knowledge of the prevalence, spectrum, and pathogenesis of such complications, and potential treatment options for them---would improve if more autopsies were performed in situations like that of the case reported by Mörz.

Physicians, nurses, hospitals, medical centers, health departments, the CDC, NIH, FDA, WHO, the American Academy of Pediatrics (AAP), the pharmaceutical industry, government leaders, and media outlets that have assured the Public that the COVID-19 vaccines are “very safe” owe it to the Public to thoroughly, openly, honestly, publicly, and prominently discuss Dr. Mörz’s article and its implications.  To date, there has been no mention of this article by the CDC, NIH, FDA, WHO, AAP, Pfizer, Moderna, government leaders, the mainstream media, or the medical experts who routinely inform the Public.  On the contrary, instead of halting the mass vaccination campaign (which is the scientifically and morally correct thing to do), the promoters of the COVID mass vaccination campaign are currently re-doubling their efforts to greatly increase vaccination rates---spending billions of dollars to maximize vaccination against COVID-19, even among infants and toddlers.  

To those people who have been encouraged, pressured, even mandated to receive COVID vaccination---physicians and scientists owe a massive top priority collaborative effort to thoroughly study the pathogenesis (the causative chain of events that lead to disease) and potential treatment of vaccine-induced endotheliopathy, vasculitis, encephalitis, and myocarditis---even if these complications prove to be rare.  The death of the 76-year-old man reported by Dr. Mörz should not go in vain. We need to determine how to promptly recognize and promptly provide optimal early treatment for vaccinated people who may be developing early evidence of similar complications in their brain, heart, both, and/or elsewhere.

In the meantime we should deeply thank Dr. Mörz for performing and publishing his extensive and careful study of this one patient.  The scientific quality of his work is excellent.  His careful article represents a major contribution to medicine and Humanity. He is to be commended for the expertise, time, effort, and courage it took to present this compelling and valuable information.  He has superbly honored the best traditions of science, medicine, and ethics and has performed a great service to Humanity.  We should also commend the journal Vaccines for demonstrating the wisdom and moral courage to publish Dr. Mörz’s article.  Like Dr. Mörz, Vaccines has honored the best traditions of science, medicine, and ethics, and has honored Humanity in the process.

Dr. Rennebohm is a pediatrician and pediatric rheumatologist.  He is currently largely retired.  In 2018 he officially retired from the pediatric rheumatology department at Cleveland Clinic, where he was also the Director of the International Susac Syndrome Consultation Service (2012-2018). Prior to that, he was at Alberta Children’s Hospital in Calgary, Canada, where he was Clinical Professor of Pediatrics and Pediatric Rheumatology (2008-2012); before that he was at Nationwide Children’s Hospital and Ohio State University in Columbus, Ohio, where he was Associate Professor of Pediatrics and Chief of Pediatric Rheumatology for 21 years; and before that he was a pediatric rheumatologist at Cincinnati Children’s Hospital Medical Center in Cincinnati, Ohio.

He went to medical school at the University of California San Diego (UCSD), at La Jolla, where he graduated with an MD degree in 1972.   He completed his Pediatric Residency training at IWK Children’s Hospital/Dalhousie University in Halifax, Nova Scotia.  He completed his Pediatric Rheumatology Fellowship training at Cincinnati Children’s Hospital Medical Center  He has been a pediatrician for almost 50 years and a pediatric rheumatologist for about 42 years.  

Although he is no longer in clinical practice or affiliated with a medical school or health care institution, he has continued his intense interests in pediatric rheumatology, Susac syndrome, and now COVID.  In fact, throughout the past 2 years he has spent many hours per day on most days of most weeks intensively studying and writing about COVID---because he has realized how profoundly important and complex the COVID situation is.

He currently lives in Seattle, Washington.  His clinical pediatrics activity is now limited to being on “first pediatric call” for his 9 grandchildren.
