Even mainstream “Medical Research” is now being published proving serious health impacts from the highly injurious COVID-19 injections.

Medical Research Keeps Revealing More COVID Vaccine Impacts

by Dr. Joel S. Hirschhorn

In the years and decades ahead, there will be a steady stream of medical research revelations about the diverse health impacts of the mRNA COVID vaccines – actually genetic therapy actions. These vaccines did not merit government approval and should not have preempted early treatment protocols that have always been highly effective. Below are discussions of two such revelations.

COVID Vaccines May Trigger Leukemia

Physicians in Taiwan diagnosed a Ph-positive B-cell acute lymphoblastic leukemia (ALL) occurring directly after the patient received Moderna’s mRNA COVID-19 bivalent (Omicron BA.4/BA.5) booster vaccine on January 3, 2023. It turns out that the 43-year-old had a total of six spike antigen exposures over the past 1.5 years (two doses of AstraZeneca, and half dose of Moderna’s monovalent mRNA vaccine and Novavax) on June 4, 2021, August 31, 2021, January 15, 2022, and July 15, 2020, respectively. While the doctors acknowledged the challenges in declaring a causal relationship between the bivalent mRNA vaccination and Ph-positive B-cell ALL, the Taiwanese doctors clearly are concerned, proposing “that anti-spike protein immune responses could be a trigger for leukemia.”

The 43-year-old woman with no problematic health record immediately after the injection felt off — with a few concerning side effects from dizziness, and mild dyspnea (breathing difficulty) to an overall general malaise. Five days after the booster dose was administered, the patient’s general malaise continued, along with worsening breathing problems, so she made it to Far Eastern Memorial Hospital Emergency Department in New Taipei City. Physicians at the emergency department observed no fever or respiratory symptoms, and she tested negative for COVID-19. Doctors reported tachycardia (119 beats/min) with normal blood pressure, and no abnormal bleeding, petechia, or ecchymosis detected. A series of other blood tests led to the identification of ALL symptoms.

As part of the case series, the Taiwanese physicians researched the incidence of hematologic malignancy occurrence after mRNA COVID-19 vaccinations. A disturbing topic, that is, the highly rare connection between mRNA vaccination and ALL. The disease itself, ALL — is rare with a poor prognosis. The 5-year overall survival equals 35% in patients aged between 18 to 60 years. The cause of adult ALL includes old age (>70 years), recent viral infection, chemotherapy or radiation exposure and genetic disorders.

How many other cases of hematologic malignancy occurring after mRNA vaccination have occurred to date? Seven (7). All cases received monovalent BNT162b2 (Pfizer-BioNTech) vaccination. TrialSite notes that these are the only cases documented and that there could be more. Four of the seven cases were identified as acute myeloid leukemia. The onset of symptoms varies, but on average, was four to five weeks after vaccination.

In the current Taiwanese case, how fast was the onset of BCR-ABL1 Ph–positive B-cell acute lymphoblastic leukemia? An amazing five (5) days.

What’s a key premise involved in this case series that will likely not make its way into mainstream media anytime soon? That “repeated spike antigen exposures involved with COVID-19 vaccination amplify the immune cell response in a condensed period of time, thereby potentially increasing incidence of B-cell acute lymphoblastic leukemia.

What does the case report authors recommend is needed?

Robust population-level studies investigation if there is an increased incidence of hematolymphoid neoplasms post-COVID-19 vaccination. Also, they argue it’s “imperative to keep monitoring the hematopoietic adverse events after these new technology bivalent mRNA COVID-19 vaccinations, especially for patients with multiple spike antigen exposures in a relatively short-term period.” Finally, the authors suggest more pre-clinical studies evaluating the safety of the COVID-19 vaccines.

New Study Shows Heart Damage After COVID Vaccine Shot

Below are some excerpts from “Myocarditis with ventricular tachycardia following bivalent COVID-19 mRNA vaccination.”

The authors report this man decompensated within a day of his fifth shot and required defibrillation, mechanical ventilation, and full life support measures for myocarditis which precipitated cardiac arrest, conduction defects, and heart failure. He stayed in the hospital for over a month. The patient was an 81-year-old man.

“Two weeks before his fifth COVID-19 vaccination, no worsening of his heart failure was detected at our regular outpatient clinic. However, on the day following bivalent BNT162b2 (wild and BA.4-5) vaccination (Pfizer–BioNTech), he was rushed to our hospital with dyspnea.”

“This report indicates the need to suspect myocarditis based on clinical presentation and the importance of multimodality diagnosis using electrocardiography, echocardiography, laboratory testing, myocardial scintigraphy, and CMR [cardiac magnetic resonance]. In our case, CMR showed LGE in the inferolateral segments of the epicardial to mid layers, which has been reported to be a characteristic finding in patient with mRNA vaccine-associated myocarditis. Endocardial biopsy is the gold standard for detecting myocarditis but is invasive and thought to have less sensitivity in disorders resulting from epicardial and patchy diseases such as myocarditis. On the other hand, CMR is considered to be the cornerstone for the diagnosis of vaccine-associated myocarditis due to its high diagnostic performance, with a reported sensitivity of 88% and specificity of 96% in community-acquired myocarditis.”

“The COVID-19 vaccine is thought to cause myocarditis via direct damage by free spike protein and induction of inflammatory cytokines (e.g., IL-1β and IL-6) by the lipid nanoparticles covering the mRNA. Expression of free spike protein may increase after the initial bivalent vaccination because antibodies against the spike protein of the BA.4-5 variant are yet to be generated. In autopsy cases, histology has shown patchy interstitial myocardial T-lymphocytic infiltration (T-cell dominant; CD4>>CD8) associated with damage to myocytes.6 Molecular mimicry between myocyte tissue and the SARS-COV2 spike protein may also produce an anti-myocytic immune response.6 Therefore, T lymphocyte-mediated cell injury and heart-specific autoimmunity have been suggested as mechanisms of post-vaccine myocarditis.”

“The COVID-19 vaccine is thought to cause myocarditis via direct damage by free spike protein and induction of inflammatory cytokines (e.g., IL-1β and IL-6) by the lipid nanoparticles covering the mRNA. Expression of free spike protein may increase after the initial bivalent vaccination because antibodies against the spike protein of the BA.4-5 variant are yet to be generated.”

The highly regarded Dr. Peter A. McCullough made this observation about the new findings:

“I wonder how many elderly patients have died within a few days of the COVID-19 vaccine, unrecognized and not reported by families, doctors, or others. Only all-cause mortality data published in the coming months to years will give us a clue. In the meantime, all seniors should understand that even if prior shots were tolerated, the next one could be fatal.”

And there have been many findings of young people dying from cardiac problems post-vaccine shots.
