The main culprit is the spike protein, if that wasn't evident by now. Either way, they can & do cause genetic mutations, hence the rise of vaccine acquired immune deficiency syndrome (VAIDS), autoimmune disorders and immunodeficiencies even if it's only for select people. Even in the preliminary trials a few people developed Bells Palsy, in case that slipped the memory.
W/ the use of the PEG2000, the vaccines bypass/incapacitate the immune systems natural response and in return are left with on-going boosters, diminished N antibodies and waning immunity altogether, not only against infection but hospitalization and death. Even Lord Fauci has finally recognized that months ago.
SARS-CoV-2 proteins and anti-COVID-19 drugs induce lytic reactivation of an oncogenic virus
Regardless of all that, I'm more concerned with my light being snuffed out afterwards and suffering from "brain fog" after the contaminants pass through the blood brain barrier.
