The study “Breaking the Silence: Recognizing Post-Vaccination Syndrome” highlights that persistent spike protein from COVID-19 vaccines edivetly contribute to long-term symptoms (PACVS) similar to long COVID. It presents evidence of spike protein remaining in the body for months, possibly triggering inflammation, autoimmunity (e.g., GPCR autoantibodies), microclotting, and neurological effects. These mechanisms are linked to fatigue, brain fog, POTS, and neuropathic symptoms.
