Study: Pfizer Vaccine Increases Myocarditis Threefold & Chinese Cupping Shows Why

Study: Pfizer Vaccine Increases Myocarditis Threefold

Analysis by Dr. Joseph Mercola Fact Checked
pfizer covid vaccine increases myocarditis threefold

Story at-a-glance

  • A large study from Israel revealed that the Pfizer COVID-19 mRNA jab is associated with a threefold increased risk of myocarditis, leading to the condition at a rate of one to five events per 100,000 persons
  • Other elevated risks were also identified following the COVID jab, including lymphadenopathy (swollen lymph nodes), appendicitis and herpes zoster infection
  • When myocarditis occurs, it reduces your heart’s ability to pump and can cause rapid or abnormal heart rhythms that can be deadly
  • In severe cases, myocarditis can cause permanent damage to the heart muscle and lead to heart failure, heart attack, stroke and sudden cardiac death; in August 2021, New Zealand reported the death of a woman following Pfizer’s COVID-19 jab, which they believe was due to vaccine-induced myocarditis
  • Due to the risk of myocarditis, Britain’s Joint Committee on Vaccination and Immunization (JCVI) recommended against COVID-9 injections for healthy 12- to 15-year-olds

As the mass administration of COVID-19 jabs continue worldwide, we’re beginning to see some of the more common side effects emerging. Myocarditis, or inflammation of the heart muscle, is among them. This condition can cause symptoms similar to a heart attack, including chest pain, shortness of breath, abnormal heartbeat and fatigue.1

A large study from Israel2 revealed that the Pfizer COVID-19 mRNA jab is associated with a threefold increased risk of myocarditis,3 leading to the condition at a rate of one to five excess events per 100,000 persons.4 Other elevated risks were also identified following the COVID jab, including lymphadenopathy (swollen lymph nodes), appendicitis and herpes zoster infection.5

Pfizer COVID Jab Poses Risk to the Heart

The real-world case-control study from Israel included a mean of 884,828 people aged 16 years and older in each of two groups: one vaccinated and one control.6 The increased risk of myocarditis was clear, with researchers noting:7

The risk appears to be highest among young men. We found that the risk of myocarditis increased by a factor of three after vaccination, which translated to approximately 3 excess events per 100,000 persons; the 95% confidence interval indicated that values between 1 and 5 excess events per 100,000 persons were compatible with our data.

Among the 21 persons with myocarditis in the vaccinated group, the median age was 25 years (interquartile range, 20 to 34), and 90.9% were male.”

When myocarditis occurs, it reduces your heart’s ability to pump and can cause rapid or abnormal heart rhythms that can be deadly. In severe cases, myocarditis can cause permanent damage to the heart muscle and lead to heart failure, heart attack, stroke and sudden cardiac death.8 In August 2021, New Zealand reported the death of a woman following Pfizer’s COVID-19 jab, which they believe was due to vaccine-induced myocarditis.9

The death prompted the Ministry of Health to issue a statement to ensure “health care professionals and consumers remain vigilant and are aware of the signs of myocarditis and pericarditis” following the jab.10

A number of studies have now found a connection between COVID-19 jabs and myocarditis. In a September-October 2021 case report with literature review, it was concluded that “the outcomes of this case scenario confirm myocarditis as a probable complication of COVID-19 vaccines.”11 Another study from Israel detailed myocarditis following Pfizer’s COVID-19 jab in six male patients with a median age of 23 years.12

A similar study published in Pediatrics13 reported seven cases of acute myocarditis or myopericarditis in otherwise healthy adolescent males. Each had experienced chest pain within four days of receiving the second dose of Pfizer’s COVID-19 jab. Data published in JAMA Cardiology14 by physicians from the Navy, Army and Air Force also revealed a higher-than-expected rate of myocarditis in U.S. military personnel who received a COVID-19 jab.

Dr. Charles Hoffe, a family physician from Lytton, British Columbia, told health officials that his patients were suffering adverse effects from the mRNA COVID-19 vaccines, including myocarditis.15 About his young, male patients, Hoffe explained, “They have permanently damaged hearts.”:16

“It doesn’t matter how mild it is, they will not be able to do what they used to do because heart muscle doesn’t regenerate. The long-term outlook is very grim, and with each successive shot, it will add more damage. The damage is cumulative because you’re progressively getting more damaged capillaries.”

Officials Advise Against Vaccination of 12- to 15-Year-Olds

Due to the risk of myocarditis, Britain’s Joint Committee on Vaccination and Immunization (JCVI) recommended against COVID-9 injections for healthy 12- to 15-year-olds. JCVI member Adam Finn told Reuters:17

“… the number of serious cases that we see of COVID in children this age are really very small. There are uncertainties about the long-term implications of (myocarditis), and that makes the risk-benefit balance for these children really quite tight and much tighter than we would be comfortable to make the recommendation.”

In the U.S., the Centers for Disease Control and Prevention (CDC) is also investigating myocarditis and pericarditis, which is inflammation of the outer lining of the heart, following mRNA COVID-19 jabs, stating that more than 1,000 cases have been reported to the Vaccine Adverse Event Reporting System (VAERS) since April 2021.18 According to the CDC:19

“As of August 25, 2021, VAERS has received 1,377 reports of myocarditis or pericarditis among people ages 30 and younger who received COVID-19 vaccine …

Most cases have been reported after mRNA COVID-19 vaccination (Pfizer-BioNTech or Moderna), particularly in male adolescents and young adults. Through follow-up, including medical record reviews, CDC and FDA have confirmed 798 reports of myocarditis or pericarditis. CDC and its partners are investigating these reports to assess whether there is a relationship to COVID-19 vaccination.”

Despite the risk, the CDC is still advising children aged 12 and older to get the jab, and August 23, 2021, the U.S. Food and Drug Administration granted full approval to Pfizer’s COVID-19 mRNA injection, now sold under the brand name Comirnaty, for people aged 16 and older.20

FDA Lists Myocarditis on Jab’s Prescribing Information

The injection’s approval represents the fastest approval in history,21 granted less than four months after Pfizer filed for licensing May 7, 2021.22 It’s also based on only up to six months’ worth of data from 44,060 people aged 16 and older.23,24 Half of them got the shots and half initially received a placebo.

However, in the second week of December 2020, Pfizer unblinded the control group and 93% of controls opted to get the real injection rather than remain in the control group for the remainder of the trial, which is slated to continue for another two years. In their prescribing information, the risk of heart inflammation is acknowledged. As reported by STAT News:25

“The FDA’s prescribing information for the vaccine includes its associated risk of myocarditis and pericarditis, two types of heart inflammation that have appeared rarely among people who’ve received the mRNA vaccines, mostly within seven days after the second shot, health officials said.

Men under 40 appear to be at higher risk than women and older men, with the highest observed risk in boys age 12 to 17.”

Further, in its approval letter for Comirnaty, the FDA orders Pfizer to conduct research to investigate the risk of inflammation in and around the heart, as voluntary reporting mechanisms are insufficient.26

The FDA accepted Pfizer’s suggested timetable for the post-approval study to evaluate incidence of heart and heart sack inflammation, which includes the submission of an interim report at the end of October 2023, a study completion date of June 30, 2025, and submission of a final report October 31, 2025.

Spike Protein in the Jab Is Inflammatory

Dr. Robert Malone, the inventor of the mRNA and DNA vaccine core platform technology,27 has been bravely warning of the dangers of COVID-19 jabs, in part due to the spike protein they contain.

In its native form in SARS-CoV-2, the spike protein is responsible for the pathologies of the viral infection, and in its wild form it’s known to open the blood-brain barrier, cause cell damage (cytotoxicity) and, Malone said, “is active in manipulating the biology of the cells that coat the inside of your blood vessels — vascular endothelial cells, in part through its interaction with ACE2, which controls contraction in the blood vessels, blood pressure and other things.”28

Malone is well aware of the actions of spike protein, as he worked to identify an effective drug that worked by blocking the action of the COX-2 enzyme, which is a key inflammatory enzyme. In one of his papers, he laid out how the spike protein and another protein in the virus directly turn on COX-2 promoter in infected cells.

This awareness of the spike protein as a biologically active protein made him alert the FDA in fall 2020 about the associated risks. His FDA colleagues transferred his concerns to the FDA’s review branch, which dismissed his concerns, saying they did not believe the spike protein was biologically active and there wasn’t enough documentation otherwise. As history now reveals, they proceeded with the EUA.

It’s since been revealed, however, that the spike protein on its own is enough to cause inflammation and damage to the vascular system, even independent of a virus.29 Blood clots are another serious concern related to the spike protein. According to Hoffe:30

“[It] becomes part of the cell wall of your vascular endothelium, which means that these cells, which line your blood vessels, which are supposed to be smooth so that your blood flows smoothly now have these little spiky bits sticking out.

So it is absolutely inevitable that blood clots will form, because your blood platelets circulate around in your vessels and the purpose of blood platelets is to detect a damaged vessel and block that damage when it starts bleeding.

So when a platelet comes through a capillary and suddenly hits all these covid spikes that are jutting into the inside vessel … blood clots will form to block that vessel. That’s how platelets work.”

Hoffe has been conducting the D-dimer test on his patients within four to seven days of them receiving a COVID-19 injection and found that 62% have evidence of clotting.31

Because of the risk of the formation of blood clots in your vessels, Dr. Sucharit Bhakdi,32 a retired professor, microbiologist and infectious disease and immunology specialist who, along with several other doctors and scientists, formed Doctors for COVID Ethics, went so far as to say that giving the COVID-19 injection to children is a crime: “Do not give it to children because they have absolutely no possibility to defend themselves, if you give it to your child you are committing a crime.”

As mentioned, due to myocarditis risks in youth, Great Britain’s JCVI is also taking a precautionary approach for COVID-19 injections among 12- to 15-year-olds. Wei Shen Lim, COVID-19 chair for JCVI, stated, “The margin of benefit is considered too small to support universal Covid-19 vaccination for this age group at this time.”33

Vaccine-Induced Thrombocytopenia With Severe Headache – Why Lyme/MSIDS Patients Should Care

Vaccine-Induced Thrombocytopenia with Severe Headache

To the Editor:

Vaccine-induced immune thrombotic thrombocytopenia (VITT), a serious adverse event after vaccination with ChAdOx1 nCoV-19 (AstraZeneca) or Ad26.COV2.S (Johnson & Johnson–Janssen), is caused by platelet factor 4 (PF4)–dependent, platelet-activating antibodies.1-3 High-dose immune globulins and anticoagulation are the main treatments.4,5 In this report, we present evidence that vaccine-induced thrombocytopenia (VIT) without associated cerebral venous sinus thrombosis (CVST) or other thromboses and with severe headache as the heraldic symptom may precede VITT (“pre-VITT syndrome”).

Eleven patients presented with severe headache in the absence of CVST 5 to 18 days after ChAdOx1 nCoV-19 vaccination.

  • All the patients had thrombocytopenia (low platelets in the blood which can cause hemorrhaging)
  • high d-dimer levels (a test to detect blood clots – a high level indicates clot formation and breakdown in the body)
  • high levels of anti–PF4–heparin IgG antibodies
  • during follow-up, intracranial hemorrhage occurred in three patients (Patients 1, 2, and 3), with radiologic evidence of new CVST in Patients 2 and 3 (Figure 1, and Table S1 in the Supplementary Appendix, available with the full text of this letter at
  • Only two patients (Patients 2 and 4) were initially admitted with conditions that met the criteria for VITT; both patients had pulmonary embolism, and additional splanchnic vein thrombosis was present in Patient 2.

In Patient 2, anticoagulation treatment had been initiated several days earlier for pulmonary embolism (without diagnosis of VITT) but was stopped after the onset of headache, shortly before CVST developed.

  • In two patients (Patients 1 and 3), peripheral thromboses were eventually identified during follow-up.

Thrombotic complications did not develop in seven of the patients (Patients 5 through 11); all but one of these patients received high-dose immune globulin, glucocorticoids, or therapeutic-dose anticoagulation within 5 days after headache onset. In contrast, in all four patients with subsequent thrombosis (Patients 1 through 4), therapeutic-dose anticoagulation either was not started until 6 to 9 days after headache onset or was stopped prematurely before the development of CVST.

Although the combination of thrombocytopenia and severe headache due to CVST has been recognized as the typical presentation of VITT,1,2 the experience with these 11 patients suggests that VIT with severe headache, elevated d-dimer levels, and strongly positive results on anti–PF4–heparin IgG enzyme-linked immunosorbent assay may precede VITT.

Our findings have immediate implications for clinical practice: in this pre-VITT syndrome, severe headache may not develop as a symptom secondary to CVST but instead may precede CVST by several days, potentially in association with microthrombosis in smaller cortical veins.

Consequently, patients who present with severe headache 5 to 20 days after adenovirus vector vaccination against coronavirus disease 2019 should undergo immediate testing for thrombocytopenia and d-dimer levels and, if available, testing for anti–PF4–heparin IgG antibodies.

When these antibodies are present at high titers, patients are at imminent risk for CVST, and it is likely that this condition can be prevented with immediate treatment, such as with intravenous immune globulin. The decision to initiate therapeutic-dose anticoagulation is a difficult one; the risk of emerging thrombosis, including CVST, has to be balanced against the risk of intracranial hemorrhage on an individual basis (e.g., with consideration of platelet count and fibrinogen levels).

Both Thrombocytopenia and severe headaches are common with Lyme/MSIDS patients.

Therapy for thrombocytopenia requires treatment or removal of the underlying infection, in addition to maintenance of platelet counts and hemostatic function.

Hopefully it’s clear that a Lyme/MSIDS patient getting a COVID shot could be diagnosed with thrombocytopenia that either already exists or worsens after the injection.  Treating the underlying infection is imperative but won’t be considered by mainstream medicine.

Myocarditis After COVID-19 mRNA Shots But Just Mask Up & Shut Up

Myocarditis after Covid-19 mRNA Vaccination

This letter was published on August 18, 2021, at


The Centers for Disease Control and Prevention recently reported cases of myocarditis and pericarditis in the United States after coronavirus disease 2019 (Covid-19) messenger RNA (mRNA) vaccination.1 In recently published reports, diagnosis of myocarditis was made with the use of noninvasive imaging and routine laboratory testing.2-5 Here, we report two cases of histologically confirmed myocarditis after Covid-19 mRNA vaccination.

Figure 1. Histopathological Findings from Endomyocardial Biopsy and Autopsy.

Patient 1, a 45-year-old woman without a viral prodrome, presented with dyspnea and dizziness 10 days after BNT162b2 vaccination (first dose). A nasopharyngeal viral panel was negative for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), influenza A and B, enteroviruses, and adenovirus (Table S1 in the Supplementary Appendix, available with the full text of this letter at A serum polymerase-chain-reaction (PCR) assay and serologic tests showed no evidence of active parvovirus, enterovirus, human immunodeficiency virus, or infection with SARS-CoV-2. At presentation, she had tachycardia; ST-segment depression detected on electrocardiography, which was most prominent in the lateral leads (Fig. S1); and a troponin I level of 6.14 ng per milliliter (reference range, 0 to 0.30). A transthoracic echocardiogram showed severe global left ventricular systolic dysfunction (ejection fraction, 15 to 20%) and normal left ventricular dimensions. Right heart catheterization revealed elevated right- and left-sided filling pressures and a cardiac index of 1.66 liters per minute per square meter of body-surface area as measured by the Fick method. Coronary angiography revealed no obstructive coronary artery disease. An endomyocardial biopsy specimen showed an inflammatory infiltrate predominantly composed of T-cells and macrophages, admixed with eosinophils, B cells, and plasma cells (Figure 1A and Figs. S2 through S4). She received inotropic support, intravenous diuretics, methylprednisolone (1 g daily for 3 days), and, eventually, guideline-directed medical therapy for heart failure (lisinopril, spironolactone, and metoprolol succinate). Seven days after presentation, her ejection fraction was 60%, and she was discharged home.

Patient 2, a 42-year-old man, presented with dyspnea and chest pain 2 weeks after mRNA-1273 vaccination (second dose). He did not report a viral prodrome, and a PCR test was negative for SARS-CoV-2 (Table S1). He had tachycardia and a fever, and his electrocardiogram showed diffuse ST-segment elevation (Fig. S1). A transthoracic echocardiogram showed global biventricular dysfunction (ejection fraction, 15%), normal ventricular dimensions, and left ventricular hypertrophy. Coronary angiography revealed no coronary artery disease. Cardiogenic shock developed in the patient, and he died 3 days after presentation. An autopsy revealed biventricular myocarditis (Figure 1B and Figs. S5 and S6). An inflammatory infiltrate admixed with macrophages, T-cells, eosinophils, and B cells was observed, a finding similar to that in Patient 1.

In these two adult cases of histologically confirmed, fulminant myocarditis that had developed within 2 weeks after Covid-19 vaccination, a direct causal relationship cannot be definitively established because we did not perform testing for viral genomes or autoantibodies in the tissue specimens. However, no other causes were identified by PCR assay or serologic examination.

Entering the ridiculous, public health officials are now asking people not to talk to stop the Covid virus. Jefferey Jaxen dives into the science behind the latest Covid mitigation suggestion.



The video is revealing on many fronts:

  • Propaganda is alive and well.
  • The paper “Viral Load of SARS-CoV-2 in Respiratory Aerosols Emitted By COVID-19 Patients While Breathing, Talking, and Singing,” has numerous disclaimers in fine print, namely, that they couldn’t mechanically retrieve and isolate a viable virus from ambient air in the vicinity of patients.  Well, that’s inconvenient.
  • This study demonstrates perfectly the hypocrisy of our corrupt public health ‘authorities’ in that they demand perfectly done randomized, controlled trials on thousands of patients to approve COVID treatments, completely ignoring clinical results, but will accept and propagate poorly done science that pushes their continued fear narrative that lines their pockets. And even when there properly done RCTs they ignore them and then go on a smear campaign to malign them, and implement bandwagon to make the public believe their accepted narrative.
  • This duplicity has been going on in Lyme-land for over 40 years and continues today.  Hopefully people are waking up to it.

Vaccine-induced immune thrombocytopenia and thrombosis (VITT) is a new syndrome associated with the ChAdOx1 nCoV-19 adenoviral vector vaccine against severe acute respiratory syndrome coronavirus 2. Data are lacking on the clinical features of and the prognostic criteria for this disorder.


We conducted a prospective cohort study involving patients with suspected VITT who presented to hospitals in the United Kingdom between March 22 and June 6, 2021. Data were collected with the use of an anonymized electronic form, and cases were identified as definite or probable VITT according to prespecified criteria. Baseline characteristics and clinicopathological features of the patients, risk factors, treatment, and markers of poor prognosis were determined.


Among 294 patients who were evaluated, we identified:

  • 170 definite cases of VITT
  • 50 probable cases of VITT
  • All the patients had received the first dose of ChAdOx1 nCoV-19 vaccine and presented 5 to 48 days (median, 14) after vaccination. The age range was 18 to 79 years (median, 48), with no sex preponderance and no identifiable medical risk factors
  • Overall mortality was 22%
  • The odds of death increased by a factor of
    • 2.7 (95% confidence interval [CI], 1.4 to 5.2) among patients with cerebral venous sinus thrombosis
    • 1.7 (95% CI, 1.3 to 2.3) for every 50% decrease in the baseline platelet count
    • 1.2 (95% CI, 1.0 to 1.3) for every increase of 10,000 fibrinogen-equivalent units in the baseline d-dimer level
    • 1.7 (95% CI, 1.1 to 2.5) for every 50% decrease in the baseline fibrinogen level
    • Multivariate analysis identified the baseline platelet count and the presence of intracranial hemorrhage as being independently associated with death
    • observed mortality was 73% among patients with platelet counts below 30,000 per cubic millimeter and intracranial hemorrhage

The high mortality associated with VITT was highest among patients with a low platelet count and intracranial hemorrhage. Treatment remains uncertain, but identification of prognostic markers may help guide effective management. (Funded by the Oxford University Hospitals NHS Foundation Trust.)



The numbers don’t lie.  

A majority of these “vaccinated” patients had VITT which explains what is happening in reality – blood clotting issues.  

  • We’ve been warned by a Canadian doctor doing D-dimer tests on his “vaccinated” patients that 62% show microscopic blood clotting.
  • A pathologist also states these injections cause severe inflammation due to the “spike protein” which is a dangerous toxin that crosses the blood-brain barrier and disrupts blood vessels throughout the body and brain.  He also reiterates that these injections are not “vaccines.”

Please notice the overall mortality of 22% and significant increased odds of death on these fully “vaccinated” individuals that have been told ad nauseam that these injections will be protective and keep you from hospitalization and death.

Lyme Carditis: Update 2021. An Evasive Diagnosis in the Time of COVID-19

Lyme disease (LD) is a tick-borne bacterial infection caused by Borrelia burgdorferi. Lyme carditis (LC) is an early-disseminated manifestation of LD, most commonly manifesting as a complete “shut-down” of the electrical system (high-degree atrioventricular block (AVB)) that can evolve rapidly over minutes, hours, or days producing severe symptoms like fainting, palpitations, shortness of breath, extreme dizziness, or sudden death (1-2).

Other cardiovascular manifestations include alterations of the “motor” of the heart (sinus node disease) (3), a disorganization of the cardiac rhythm that increases the risk of stroke (atrial fibrillation) (2), lesion in the distal cables of the heart (bundle branch blocks) (4), and different degrees of inflammation of the layers of the cardiac walls (myocarditis, pericarditis, and endocarditis) (2). Some of these manifestations could be so severe that a total dysfunction of the cardiac function occurs in a matter of hours, and the patient may die even if admitted to the best ICU in the world.

The initial symptoms of LD can be mistaken by other common infections or allergic reactions. Delayed diagnosis is one of the most important risk factors to serious LD presentations including LC in all its forms. The good news is that prompt diagnosis and appropriate antibiotic therapy links to a much better prognosis. In addition, we now know that when appropriately treated with antibiotics according to guidelines (2); there is no evidence of residual disease in the heart (5).

Most conduction abnormalities caused by LC resolve with appropriate antibiotic therapy (2).

The current COVID-19 pandemic is posing a new challenge in the diagnosis of LD. There are lots of overlapping symptoms such as: fever, malaise, generalized pain, lack of energy, etc. During these times, one would advise on ruling out COVID-19 first before embarking on any other test. However, what could we recommend in terms of confirming or ruling out LD, specifically during these challenging times?

Learning how to recognize the many presentations of LD from a clinical point of view has been published several times. It is especially important to ask about outdoor activities, history of tick bites, tick removal and dermatological rashes (remember that the classic “bull eye” is only present in about 40% of cases). Extensive dermatologic examination may be necessary. Residence in an endemic region for LD is essential for risk stratification, as these recommendations should be encouraged in all ED and family doctor offices in areas of high prevalence.

Once the diagnosis is suspected, specific interrogation should be directed to cardiovascular symptoms such as: dizziness, palpitations, fainting or near fainting, chest pain and shortness of breath. If the patient recognizes any of these symptoms, along with any other factors suggesting LD, a 12-lead ECG (the simple and unexpensive electrocardiogram) should be performed (2). Any evidence of electrical disturbance should prompt admission in hospital for a course of IV antibiotics while waiting the results of serological tests.

On the other hand, in patients presenting with unexpected high-degree AV block, clinical suspicion for LC can be assessed using the validated risk score called SILC (Suspicious Index in Lyme carditis) (6) where the acronym COSTAR(Constitutional symptoms, Outdoor activities/endemic region, Sex male, Tick bite, Age > 50, Rash) may help in determining the risk of presenting early disseminated LC.

In summary, use your clinical tools to suspect LD in the context of COVID-19 pandemic, order serological tests when appropriate, and remember to check for cardiovascular complications with a history, physical, and ECG. If evidence of LC, admit the patient to hospital with continuous cardiac monitoring and appropriate IV antibiotics. Decision for permanent pacemaker implantation should wait until completion of antibiotics as heart block in LC is often reversible. Most patients maintain normal rhythm on long-term follow-up. Avoiding unnecessary implants is crucial as most of these patients are young and active individuals.
