Even as we enter 2026, millions of people around the world still have the COVID spike protein in their body. This isn’t up for debate. It’s been confirmed. Feel free to check for yourself. Testing The most sensitive test is by LabCorp, it is called: SARS-CoV-2 Semi-Quantitative Total Antibody, Spike. Test code is 164090. The good thing about this test is that it is very sensitive and actually gives you the exact number of COVID spike protein antibodies in your body. The test takes about 1-3 day to return, which is pretty quickly. Many people get it checked from Quest, called: SARS COV 2 AB, TOTAL SPIKE SEMI QN, but the problem is that the Quest test maxes out it’s value at 2,500. So it does not register a value over 2,500, it just says ‘over 2,500.’ The majority of people who had COVID, and everyone who had at least 1 vaccine will likely still be over 2,500. So doing the test with Quest is not sensitive enough. What if they have 10,000 U/ml? 20,000 U/ml? There’s no way to know if they...

Dr. McCullough explained 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. He cited more than 300 papers documenting spike deposits in the heart, brain, and vascular tissue, relating these findings to post‑vaccine myocarditis, strokes, and clotting disorders. A chief diagnostic ste...

Abstract Background: Long COVID, or post-acute sequelae of SARS-CoV-2 infection (PASC), continues to affect millions globally. Persistent symptoms include fatigue, cognitive impairment, dyspnea, autonomic dysfunction, and multi-organ involvement. Objectives: To summarize the latest 2026 research on biological mechanisms, clinical features, risk factors, and treatment approaches for Long COVID. Methods: Literature review of peer-reviewed publications, government reports, and large cohort studies from 2023–2026, using PubMed, PMC, NIH RECOVER data, and major news outlets reporting verified research. Results: Key mechanisms identified include persistent inflammation, microvascular thrombosis, immune dysregulation, autonomic nervous system involvement, and in some patients, neurodegenerative protein elevations. Reinfection and pre-existing comorbidities are significant risk factors. Current management remains symptom-focused and multidisciplinary. ...
