Given the recent and abundant evidence that the S1 subunit of the SARS-CoV-2 spike protein damages blood vessels, is it perhaps more than likely that the spike is being cleaved and the cleaved S1 unit is attacking blood vessels? 

If one notes the "side effects" of the spike protein therapies, they are PRECISELY the same as VASCULITIS:

Hay fever

Fever

Loss of appetite and weight loss

Joint and muscle pain

Fatigue

Cough Abdominal pain and gastrointestinal bleeding

Weakness, fatigue or a general feeling of being unwell

Rash or skin sores

Pain, numbness and tingling in your hands and feet

Severe abdominal pain

Shortness of breath

If the blood vessels in the heart are being attacked by the spike, this would cause Acute Coronary Syndrome. This chorus now sounds all too familiar:

Chest pain (angina) or discomfort, often described as aching, pressure, tightness or burning

Pain spreading from the chest to the shoulders, arms, upper abdomen, back, neck or jaw Nausea or vomiting

Indigestion

Shortness of breath (dyspnea)

Sudden, heavy sweating (diaphoresis)

Lightheadedness, dizziness or fainting

Unusual or unexplained fatigue

Feeling restless or apprehensive

Investigation into biomarkers for vasculitis in recipients of spike protein therapies must be done immediately. All spike protein therapies must be paused while this possibility is investigated.
