Spike proteins administered intravenously are engineered to cross the blood-brain barrier, can cause cerebral hemorrhage

1
(Natural News) A study from Nature Neuroscience finds the S1 spike protein of SARS-CoV-2 crosses the blood–brain barrier in mice and can cause damage to the cardiovascular and central nervous systems. The spike protein is readily cleared from the blood and taken up by peripheral tissues. SARS-CoV-2 RNA was recovered from cerebrospinal fluid, proving it…
