The Spike Protein Hypothesis:
Dr. Peter McCullough’s Ottawa Testimony to Members of Parliament
Thomas Lee Abshier, ND | 14 September 2026
In September 2026, Dr. Peter McCullough testified for about an hour before a hearing in Ottawa hosted by members of Canada’s Parliament. McCullough is a Dallas internist and cardiologist who, before the pandemic, had spent three decades as one of the most published academic cardiologists in the United States — roughly a thousand papers, much of it on the interaction of heart and kidney disease, and a long record of editorial and professional-society leadership. It was that standing that gave his voice weight when, in the summer of 2020, he began to dissent publicly from official COVID-19 policy, and it is that standing he has spent since. The hearing had spent three days listening to Canadians who attribute serious illness to COVID-19 vaccination. McCullough was placed on the final day to explain what he believes is happening in their bodies and what he does about it in his own practice.
I have read the full transcript. What follows is a summary of his argument in my own words, followed by an honest assessment of which parts rest on solid ground, which are plausible but unproven, and which are speculation dressed as certainty. I do this because a physician who wants to be useful to his patients cannot afford to accept or dismiss a body of claims wholesale. McCullough is a serious clinician and researcher who has examined thousands of these patients and published on what he found. He is also, since 2020, a man whose rhetoric has at times run ahead of his evidence. Both things are true, and the reader deserves to know which claims are which.
The argument, as McCullough made it
His case runs as follows.
The SARS-CoV-2 virus carries about thirty proteins. One of them, the spike, is the one that does the damage: it is the part that docks with the ACE2 receptor, and in McCullough’s telling it was engineered in a US–Chinese collaboration to be unusually effective at invading the respiratory tract. Every COVID-19 vaccine that reached the market chose the spike as its antigen. McCullough argues this was unprecedented — that vaccinology has always used an attenuated or detoxified form of a pathogen’s harmful component, as tetanus toxoid stands in for tetanus toxin, and never the fully active harmful component itself.
The mRNA vaccines compounded the problem, he says, by encoding this protein on a synthetic messenger RNA in which uridine was replaced with pseudouridine — the modification for which Karikó and Weissman won the Nobel Prize — precisely so that the body’s enzymes would not degrade it. The RNA was packaged in lipid nanoparticles that distribute throughout the body, crossing the blood–brain barrier and entering the eye. The result, he argues, is that cells all over the body produce full-length spike protein in quantities many times greater than an infection would deliver, with no biological switch to turn production off.
From this he derives the diversity of injury syndromes the hearing had heard: myocarditis, blood clots, aneurysm, blindness, transverse myelitis, autoimmunity. The spike, he says, has sequence homology with several dozen human proteins and so incites autoimmune reactions; it is unusually procoagulant, capable of triggering clotting even without platelets; and it is amyloidogenic — it can misfold into rubbery aggregates, which he offers as the explanation for the large fibrous clots that embalmers have reported finding in the deceased.
Why, then, is everyone not injured? McCullough said this was the hardest question he had ever been asked, and that he now has an answer with three parts: the dose of RNA varied enormously between vaccine lots; individuals vary in their baseline vulnerabilities, so that a person with a clotting tendency gets clots and a person with a myocardial protein polymorphism gets myocarditis; and, most importantly, individuals vary in the quality of the antibodies they raise. If a person’s antibodies neutralize spike perfectly, he is spared. He cited a Harvard study of boys with vaccine myocarditis whose antibodies, unlike those of unaffected controls, failed to neutralize circulating spike.
He then turned to persistence. His group has published a case in which vaccine mRNA and spike protein were detected in a patient’s blood three and a half years after his last dose, and he pointed to other groups — Brogna in Italy, a team at Yale — reporting mRNA detectable for months. He described finding fragments of the Pfizer sequence in a bladder tumor from a woman in her thirties and in a cardiac tumor from a man who had taken three doses, and he raised the prospect of rising cancer incidence, particularly solid tumors in the young, as a delayed consequence of both infection and vaccination.
Finally, the clinical program. He recommends that anyone with a vaccine-injury syndrome obtain a quantitative spike antibody titer — a commercial assay costing under a hundred dollars in the United States — as a proxy for spike burden. Below 1,000 units he regards the patient as clear; above 5,000 he expects to find spike in the blood. His base protocol combines three over-the-counter agents — nattokinase, bromelain, and curcumin — with the aim of enzymatically degrading the spike, and he adds colchicine for myocarditis, low-dose rapamycin in selected cases, hydroxychloroquine for autoimmune presentations, ivermectin for suspected viral reservoir, N-acetylcysteine, hyperbaric oxygen, and therapeutic sweating in a sauna. He said recovery takes as long as the illness has lasted — two or three years of treatment for two or three years of sickness — and that he has never seen a patient recover without first clearing the spike.
His political conclusion was blunt: the vaccines should have been withdrawn in 2021, no country has performed a proper safety review or opened vials to check their contents, Canada is nearly alone in continuing to vaccinate children, and the injured should stop waiting for institutions and take their own care into their own hands.
What is solidly established
Several of McCullough’s claims are not controversial among people who read the literature, however unwelcome they remain in official communications.
Myocarditis. That the mRNA vaccines cause myocarditis, concentrated in adolescent and young adult males and clustering after the second dose, has been acknowledged by every major regulator since mid-2021. The fatal case of a 42-year-old man published in the New England Journal of Medicine is real; the Israeli military reports are real; the autopsy-confirmed deaths in teenage boys are real. Whether the rate justifies the word “rare” is a value judgment, and McCullough’s position — that a vaccine given to a healthy person is held to a different standard than a drug given to a sick one, and that one avoidable death is one too many — is a defensible ethical stance, not a fringe one.
The risk–benefit picture in children. Healthy children were at near-zero risk of death from COVID-19 throughout the pandemic. Most countries have quietly stopped recommending routine vaccination for them. Canada’s continued recommendation for infants and children is, as McCullough said, an outlier, and the burden of justifying it rests on those who make it.
Biodistribution. The claim that lipid nanoparticles stay in the deltoid was never supported by the manufacturers’ own animal data, which showed distribution to liver, spleen, adrenals, and ovaries. That the spike protein is produced systemically rather than locally is not seriously disputed.
The absence of independent quality control. It is simply true that no national regulator has published a systematic analysis of commercial vaccine vials for mRNA concentration, DNA contamination, or lot-to-lot variation. Independent laboratories that have looked have reported findings that deserve a formal answer. The failure to conduct this analysis is a scandal of process regardless of what the analysis would find.
Pre-pandemic planning. The mRNA platform was under military-funded development for years before 2020. This is a matter of public record and not a conspiracy theory, though it is also not evidence of malice; that is what pandemic preparedness looks like.
What is plausible but not proven
Persistence of spike and mRNA. Here McCullough is ahead of the consensus but not outside the literature. Several peer-reviewed reports have detected vaccine mRNA or spike protein in blood, lymph nodes, or tissue well beyond the days-to-weeks timeframe that official sources still cite. His own case report at three and a half years is a single patient, and one must always ask whether the assay is specific and whether the detected material is biologically active. But the pattern across multiple groups is enough to make persistence a live scientific question, and the refusal of agencies to engage with it is not a scientific position.
Spike antibody titer as a clinical proxy. The commercial assay measures antibody to the receptor-binding domain, not spike itself. McCullough asserts a correlation of 0.8–0.9 with spike burden. I have not seen that correlation established in a large independent sample, and a titer will be elevated by any recent infection. Using it to track a trend in an individual patient over time is reasonable; using fixed thresholds — 1,000, 5,000 — as diagnostic cut-points is his own clinical convention, not a validated standard.
Amyloid-like clotting. Laboratory work has shown that spike protein can induce fibrin to form dense, protease-resistant aggregates, and this is a plausible mechanism for the unusual clots described by embalmers. But the embalmer survey McCullough cited is a self-selected questionnaire, not a pathology study, and — as he acknowledged — the finding is reported in the unvaccinated as well. The honest interpretation is that spike from any source may promote abnormal clotting; the vaccine-specific attribution requires controlled autopsy data that no one has produced.
Cancer. The mechanisms McCullough listed — impairment of DNA-repair pathways, suppression of tumor immune surveillance, the shift toward tolerogenic IgG4 after repeated dosing — are each supported by at least some experimental work. Finding vaccine sequence fragments in two tumors is intriguing and demands follow-up. But two case reports are not an epidemiological signal, and the rise in early-onset cancer began years before 2020 and has many candidate causes. “Turbo cancer” is a phrase that outruns its evidence. The right posture is vigilance and registry-level surveillance, which, to his point, no one is doing.
What is speculation presented as certainty
“Engineered to kill.” That SARS-CoV-2 emerged from laboratory research in Wuhan is now taken seriously by a number of intelligence agencies and scientists, and the furin cleavage site remains unexplained by natural evolution. But the further claim that the spike was deliberately designed as a lethal weapon is an inference McCullough stated as fact. It is not established, and stating it as established weakens everything that follows by inviting the reader to dismiss the whole.
“Indestructible.” McCullough repeatedly said that no human enzyme can degrade the spike protein or the modified RNA. This is not correct. Pseudouridine slows degradation of the RNA; it does not make it immortal, and the body’s proteases handle a great many foreign proteins, including spike. The genuine question is whether clearance is slower than assumed and whether some individuals clear poorly — which is a very different claim from the one he made, and a more defensible one.
“No valid study shows the vaccines reduced hospitalization or death.” This is the claim in his testimony that I find hardest to credit. Whatever one concludes about net harm in the young, the observational literature from 2021 in the elderly and high-risk consistently shows reduced severe outcomes in the months after vaccination, before waning. That the protection was brief, that it did not stop transmission, and that repeated boosting has a poor and possibly negative return are all fair criticisms. Denying that any benefit ever existed is not.
The enzyme protocol. Nattokinase and bromelain degrade spike protein in a test tube; the Tanikawa work he credited is real and worth reading. The unanswered question is whether orally administered enzymes reach systemic circulation in active form at meaningful concentrations. Bromelain has measurable, if modest, absorption; nattokinase’s is contested. McCullough’s evidence for efficacy is his own uncontrolled clinical series — antibody titers falling over two years in patients who were also being treated with colchicine, anticoagulants, and time. A titer that falls over two years is what one would expect from the natural decay of antibody after any antigen exposure. This does not mean the protocol is useless; the agents are cheap, generally safe under supervision, and have independent rationale as anti-inflammatory and fibrinolytic support. It means that “it dissolves the spike” has not been demonstrated in a living person.
Sweating out the vaccine. McCullough proposed that mRNA and spike exit the body through perspiration, and offered the recovery of athletes after the early wave of cardiac events as evidence. Proteins and nucleic acids are not, as a rule, excreted through sweat in any quantity, and the athletes’ recovery is more parsimoniously explained by myocarditis healing on its own, which it usually does. Sauna has real cardiovascular benefits and I recommend it freely; I would not tell a patient it is removing the Pfizer sequence from his cells.
What the testimony is worth
It would be easy for a critic to seize on the weak claims and use them to bury the strong ones. It would be equally easy for a sympathizer to treat McCullough’s confidence as proof. Neither serves a sick patient.
The real value of his testimony lies in three things. First, he has articulated a coherent mechanistic hypothesis — systemic spike exposure, variable neutralization, tissue-specific injury according to individual vulnerability — that explains the otherwise bewildering diversity of post-vaccination syndromes better than any competing account I have seen, including the official account that there is nothing to explain. Second, he has done what no regulator has been willing to do: he has measured, biopsied, and followed these patients, and published what he found. Third, he has given the injured something to do — a test, a trend to follow, a set of low-risk interventions, and a timeframe — when the alternative on offer was psychiatric referral.
The naturopathic tradition has always held that the body is trying to heal and that the physician’s task is to remove obstacles. McCullough’s practice, stripped of its rhetoric, is exactly that: identify the persistent foreign material, reduce it as far as the tools allow, calm the inflammation it provokes, and give the patient time. That is sound medicine whether or not nattokinase ever crosses the gut wall.
What I would ask of him, and of the movement he leads, is proportion. Every overstatement — “designed to kill,” “indestructible,” “never reduced a single death” — is a gift to the institutions that would rather not answer the questions he is right to ask. The vaccine-injured need those questions answered. They do not need a prophet. They need a physician who says what he knows, admits what he suspects, and marks the difference clearly enough that a Canadian parliamentarian, or a patient reading a website in Montana, can tell one from the other.
