Fact Check: Unpacking the Spike Protein Debate (2025)

1. Yale News Article (February 19, 2025)

Title: "Immune markers of post-vaccination syndrome indicate future research directions"

Key Points:

• The article discusses a Yale study (published on medRxiv) investigating post-vaccination syndrome (PVS), a condition where a small number of people report chronic symptoms after COVID-19 vaccination.
• The study included 42 participants with PVS and 22 healthy vaccinated controls, analyzing blood samples for immune markers.
• It notes that PVS is not officially recognized by medical authorities, and little is known about its biological basis.
• The study is framed as an initial step to characterize PVS, identifying potential immunological patterns that differ between PVS patients and controls.

2. MedPage Today Article (Feb 20, 2025)

Title: "Researchers Describe Rare Syndrome After COVID Vaccine"

Key Points:

• The article reports on the Yale study, specifically noting that detectable levels of the S1 subunit of the spike protein were found in plasma up to 709 days after vaccination in some PVS patients.
• Dr. Akiko Iwasaki, a lead researcher, expresses surprise at this finding, as the persistence of spike protein at such a late time point is unexpected.
• The article compares PVS to long COVID, noting similarities like exercise intolerance and neurologic issues, and mentions that persistent spike protein has been associated with long COVID as well.

3. MedRxiv Preprint (February 18, 2025)

Title: Immunological and Antigenic Signatures Associated with Chronic Illnesses after COVID-19 Vaccination (MedRxiv)

Key Points (Based on Web Result Summaries):

• This is the primary source of the Yale study, led by Akiko Iwasaki and colleagues.
• It confirms that some PVS participants had detectable SARS-CoV-2 spike protein in their bloodstream, with persistence up to 709 days post-vaccination.
• The study highlights immune dysregulation and increased markers of inflammation in PVS patients.
• As a preprint, this study has not yet been peer-reviewed, meaning its findings are preliminary and subject to further scrutiny.

4. Reuters Fact Check (March 7, 2025)

Title: "Fact Check: US study does not suggest long COVID is a vaccine injury"

Key Points:

• The article addresses a misleading claim on social media that the Yale study suggests long COVID is a vaccine injury.
• It clarifies that the study’s authors (including Harlan Krumholz, a co-senior author) and independent experts reject this interpretation.
• The study found spike protein persistence in some PVS patients, including those without prior COVID infection, but this does not imply that long COVID is caused by vaccines.

5. The Wellness Company X Post (March 25, 2025)

• Spike protein can be detected for at least 709 days after vaccination (X Post).
• This is supported by the Yale study (medRxiv preprint, MedPage Today). The study found detectable S1 subunit levels in some PVS patients up to 709 days post-vaccination.

Analysis and Evaluation

Scientific Accuracy

• Spike Protein Persistence (709 Days): The claim that spike protein can be detected for 709 days is accurate and directly supported by the Yale study. However, the study emphasizes that this was observed in a subset of PVS patients, not the general population, and the implications of this persistence are unclear.

Context of Post-Vaccination Syndrome (PVS)

• PVS is a poorly understood condition, and the Yale study is one of the first to investigate its immunological basis. The study’s findings are preliminary (as it’s a preprint) and should be interpreted cautiously.
• The persistence of spike protein in some PVS patients is notable.
• It’s important to understand that 320 peer-reviewed scientific studies demonstrate that the Spike protein is highly pathogenic on its own and causes damage to all organ systems while persisting in the body for years. Thus, it can be reasonably assumed that clearing the body of this potent toxin is a key step toward addressing post-vaccination syndromes and long-COVID.

Conclusion and Recommendations

• If you’re intrigued by the Yale study, it’s a legitimate piece of research that highlights the need for further investigation into PVS. However, its findings are preliminary, and the implications of spike protein persistence are not yet clear.
• If you’re concerned about PVS or vaccine side effects, consult a healthcare provider rather than relying on unproven supplements. The scientific community is still learning about PVS, and more research is needed to understand its causes and potential treatments.
