“When I first heard about it [HBOT] I thought, ‘this is goofy,’” said Dr. Paul Marik. Then he encountered a competitive cyclist patient who became bedridden after COVID vaccinations. “He was completely incapacitated. He went for hyperbaric oxygen [and] within about five or six sessions [he] was back on his bicycle.”
Marik, co-founder of the Front Line COVID-19 Critical Care Alliance (FLCCC), told The Epoch Times, that some patients who have spike protein injuries have responded particularly well to hyperbaric oxygen.
Dr. Paul Marik, co-founder of the Front Line COVID-19 Critical Care Alliance (FLCCC) and former Chief of the Division of Pulmonary and Critical Care Medicine at Eastern Virginia Medical School, at the FLCCC conference “Understanding & Treating Spike Protein-Induced Diseases” in Kissimmee, Fla. on Oct. 14, 2022. (The Epoch Times)
How Does HBOT Work?
Hyperbaric oxygen therapy (HBOT) involves patients breathing in 100 percent pure oxygen in a chamber at an atmospheric pressure higher than normal sea level (1 standard atmosphere, or ATM).
Since oxygen normally only makes up around 21 percent of air, the increased pressure of pure oxygen would further increase oxygen levels in the blood.
Depending on the pressure administered, blood oxygen levels can be increased to three times the normal level.
The treatment is mostly used for wound healing, including both internal and external wounds.
Cells need oxygen to function. The mitochondria uses oxygen to break down sugars into energy, so increased blood oxygen levels drive tissue growth and regeneration. Increased oxygen levels also clear bacterial infections.
HBOT is currently approved as a treatment for 15 different wounds and health conditions including carbon monoxide poisoning, tissue damage, blood loss, burns, skin grafts, soft tissue infections, and intracranial abscesses.
Outside of the United States, Russia lists 70 diseases that can be treated by HBOT, China lists 49, and Japan lists 33.
Dr. Paul Harch, a renowned HBOT expert and founder of Harch Hyperbarics, said at the FLCCC conference in Kissimmee, Florida that a major underlying pathology of wounding is inflammation; HBOT repairs wounding by reducing inflammation and promoting regrowth.
Since inflammation is an underlying pathology for many diseases, this makes HBOT conceptually applicable for various conditions, even wounding from diabetes, which is a metabolic disease driven by inflammation.
Epigenetics are factors that change gene activity. Depending on environmental factors including stress, diet, drugs, and treatments, certain genes can be activated or suppressed.
“Surprisingly, it is the increased pressure, rather than the increase in the concentration of dissolved oxygen, that appears to mediate these effects,” the FLCCC doctors wrote in their treatment recommendations.
For HBOT, the higher the oxygen pressure, the greater the change in gene expression, and the higher the general benefit.
Therefore the FLCCC recommends to use HBOT at a high atmospheric pressure. But treatment regimens need to be monitored by a clinician to prevent oxygen toxicity.
An in vitro study on human microvascular cells found that cells exposed to a HBOT treatment at 2.4 standard atmospheres (ATM) for 60 minutes, had changes in gene expression in 8,101 genes 24 hours later.
HBOT increased the expression of anti-inflammatory genes and reduced the activity of pro-inflammatory genes.
Since cells exposed to pure oxygen at normal atmospheric pressure had “minimal change” in their gene expression, this demonstrated that pressure is the key player in the overall therapy.
Another study on rats further indicated the importance of pressure. The study showed that depending on the pressure of the environment, different numbers of genes were expressed.
The authors of the study exposed rats to normal air and pure oxygen at normal atmospheric pressure and higher pressures. The data showed that in rats, as oxygen levels increased from the pressure would cause an increase in gene expression.
Physiological Changes From Hyperbaric Oxygen
HBOT is currently recommended as a third-line treatment for post-vaccine symptoms, coined under the umbrella term of post COVID vaccine syndrome.
FLCCC doctors reason that both long COVID and post-vaccine symptoms are driven by a chronic exposure to spike protein, which promotes immune dysregulation and inflammation, this therefore makes conceptual sense that HBOT may work as a potential treatment.
Studies showed that HBOT could reduce inflammatory pathways and reduce the action of pro-inflammatory toll-like receptor pathways, both of which are often activated in acute COVID infections and spike protein-induced diseases.
Mitochondria are responsible for breaking down the sugar we ingested through our food, into energy, and uses oxygen as a key reactant of this biochemical process.
During inflammation experienced in long COVID and post-vaccine syndromes, the spike protein can stress the mitochondria in the cell, leading to reduced energy production and more production damaging radical species. Therefore the extra oxygen provided through the treatment gives ample material for use by the mitochondria to increase energy production for the body.
HBOT also induces the release of stem cells and tissue growth factors.
Many studies found the treatment to be beneficial in promoting tissue regeneration including the regeneration of muscle cells and generation of new blood vessels, this indicates that HBOT can help in the repair of tissue damaged from spike protein injuries.
Neurological symptoms are some of the major symptoms in long COVID and post-vaccine symptoms. There are also studies that showed that HBOT enhanced neurogenesis, though HBOT has not been approved by the Foods and Drug Administration for such treatment yet.
Harch has had successes in treating wounds in the brain including a near-reversal of brain damage in a drowned 2-year-old girl in 2017.
The girl had suffered from a deep brain injury and had “no speech, gait or responsiveness to commands with constant squirming and head shaking” he said.
But following 40 sessions, the girl had near-normal motor function, normal cognition, gait, and temperament, and improvement on nearly all neurological exam abnormalities. Her speech improved to a greater level than pre-drowning and she also discontinued all of her medications, according to the LSU Health New Orleans School of Medicine media release.
Studies have also found HBOT treatments increased blood flow and induced microstructural changes; this led to improved brain function including cognitive functions, gait, and sleep.
HBOT for Spike Protein-Induced Diseases
Studies on HBOT therapies have shown it to be beneficial against COVID and long COVID. There is much literature on HBOT that find positive outcomes in treating COVID infections.
All of the COVID patients presented low oxygen levels, rapid breathing, and inflammatory markers. After one to six sessions of HBOT, inflammatory markers fell and the rapid breathing ceased.
“Most importantly, HBOT potentially prevented the need for mechanical ventilation,” the authors wrote.
In a randomized controlled study from Argentina, HBOT was used to treat for low oxygen in COVID-19. The study was stopped after the interim analysis of 40 patients’ outcomes. The differences between the treatment and the non-treatment group were obvious.
Patients under treatment for HBOT improved their blood oxygen levels in three days, compared to the non-treatment group which took 9 days.
In particular, studies on long COVID showed that HBOT has significant improvements on fatigue, and brain fog by improving attention, memory, information processing, and mental health.
In an Israeli study published in July 2022 on 73 long COVID patients, half (37) were treated with HBOT and the other half (36) with placebo. The patients received treatments five times a week and the protocol included breathing pure oxygen by mask at 2 ATM for 90 minutes.
The authors noticed improvements in the HBOT treatment group in global cognitive function, attention, and executive function, with significant improvements in energy, sleep, mental health, and reduced pain.
Brain scans of these patients further showed improved blood flow in certain areas of the brain, suggestive of blood vessel formation.
The FLCCC recommends HBOT as a third line treatment as it is considered to be a treatment that “may be lifesaving for one patient and totally ineffective for another,” and is therefore less applicable for the general population.
Marik also acknowledged that the high cost of the therapy and differences in pathophysiology may not make the treatment suitable for everyone. They currently recommend HBOT only for severe neuropathologies in patients suffering from post-vaccine syndromes, particularly peripheral neural pain. Contraindications for this treatment include people with untreated pneumothorax.

Base Spike Detox According to Dr Peter McCullough (in a X/Twitter post): Base Spike Detox is what I am currently using in my practice for those who have had COVID-19 multiple times, one or more of the COVID-19 vaccines, or both and believe persistent SARS-CoV-2 Spike protein could be causing problems in their body. I have arrived, based on the emerging scientific literature (1) and my clinical observation, that three OTC products are essential as a triple base combination: Nattokinase 2000 FU (100 mg) twice a day — take on an empty stomach Bromelain 500 mg once a day — take on an empty stomach Nano/Liposomal Curcumin 500 mg twice a day — take with food How long should I take this? Dr. McCullough recommends a minimum of 3 months , with many patients requiring 6–12 months or longer. Progress can be tracked via a spike protein antibody test (available through Labcorp in m...

Dr. McCullough explained (1) that the spike protein is an engineered, synthetic molecule roughly 1,200 amino acids long and resistant to degradation by the body’s normal proteases. He described how the protein was modified in laboratory settings (notably at the Wuhan Institute of Virology) to tightly bind to the ACE2 receptor, which is found throughout the body—in the lungs, heart, endothelium, kidneys, and brain. Because this receptor regulates angiotensin metabolism, older individuals with fewer ACE2 sites catabolize the spike less efficiently, leading to worse outcomes. Whether introduced by infection or by genetic‑code‑based vaccines, McCullough asserted, the persistent spike damages tissues directly and through chronic inflammation, micro‑clotting, and autoimmune cross‑reactivity.

The McCairn Protocol (Edogawa–McCairn Protocol): Overview and Mechanistic Rationale The McCairn Protocol (also referred to as the Edogawa–McCairn Protocol ) is an experimental, two-phase treatment approach promoted by Kevin McCairn in collaboration with Edogawa Hospital. It is primarily proposed for individuals with Long COVID and post-mRNA vaccine–associated syndromes , targeting hypothesized drivers such as persistent spike protein, amyloid-like fibrin microclots, autoantibodies, chronic inflammation, and associated vascular or neurological dysfunction. Phase 1: Double Filtration Plasmapheresis (DFPP) / Plasma Adsorption (“Cleansing”) Double Filtration Plasmapheresis (DFPP) is a specialized form of therapeutic apheresis currently used in parts of Asia, including Japan, for selected autoimmune, neurological, and metabolic conditions. Procedure Blood is withdrawn, often via a large-bore catheter (e.g., internal jugular access). It is passed through a dual-filtration syste...
Can you remove spike proteins from your body? Dr. Paul Marik and Dr. Pierre Kory are pleased to introduce the I-RECOVER: Post-Vaccine Treatment protocol, designed to help people who have experienced adverse symptoms after a COVID vaccine. Kory and Marik are both part of the FLCCC*, which was founded in 2020 to share early treatment protocols for COVID-19. Kory is an ICU specialist, triple board certified in internal medicine, critical care and pulmonary medicine. He now runs a private tele-health practice specializing in the treatment of COVID-19, so-called "long-COVID" and post-vaccine syndrome. *The FLCCC Alliance is now the Independent Medical Alliance Note that there are significant overlaps between the symptoms and features of long COVID/long-hauler syndrome and post-vaccine syndrome. However, a number of clinical features appear to be characteristic of post-vaccine syndrome; most notably, severe neurological symptoms appear to be more common following vaccination. To c...

America Out Loud - Our show this week is an excerpt from the BS Free MD Podcast, where Drs. May and Tim Hindmarsh speak with cardiologist and internist Dr. Peter McCullough, a leading scientist investigating long COVID and post-vaccine syndromes. The conversation dives into the evolving understanding of spike-protein–related illness, McCullough’s ground-breaking research linking persistent spike protein exposure to long-term disability, and his practical “McCullough Protocol-Based Spike Detoxification” approach. Dr. May Hindmarsh shares her personal struggle: after severe COVID infections, menopause, and hormonal treatment, her health deteriorated—with rapid heart rate, mast-cell activation, histamine sensitivity, anxiety, insomnia, and gastrointestinal distress. She later discovered her blood test showed sky-high anti–spike protein antibody levels (>12,000 U/mL on LabCorp testing). McCullough explains that such titers correlate with circulating spike protein fragments, even years ...
Introduction and Context The concept of "turbo cancer"—rapidly progressing cancers allegedly linked to COVID-19 mRNA vaccines—has gained widespread attention. A recent preprint study (July 2025) exploring transcriptomic dysregulation in individuals with new-onset adverse events or cancers following mRNA vaccination introduces preliminary molecular data that may warrant further investigation. This article critically reviews the origins of the "turbo cancer" narrative, current scientific literature including emerging molecular studies, and emphasizes the need for evidence-based analysis when considering health claims related to vaccination. This independent article aims to cut through the noise by providing a fact-based exploration of 'turbo cancer' or 'aggressive cancer'. Drawing on peer-reviewed studies, expert insights, and data from health authorities, we unpack common claims, clarify the science, and address lingering myths. Our goal is to empo...
Over the last three years, the COVID-19 pandemic has transformed almost every aspect of our lives before we've had time to stop and question it. Although no official definition exists for post-COVID-vaccine syndrome, a temporal correlation between a patient receiving a COVID-19 vaccine and beginning or worsening of clinical manifestations is sufficient to diagnose as a COVID-19 vaccine-induced injury, when the symptoms are unexplained by other concurrent causes. Dr. Paul Marik and Dr. Pierre Kory are pleased to introduce the I-RECOVER: Post-Vaccine Treatment protocol, designed to help people who have experienced adverse symptoms after a COVID vaccine. Kory and Marik are both part of the FLCCC ( The FLCCC Alliance is now the Independent Medical Alliance ), which was founded in 2020 to share early treatment protocols for COVID-19.
