The SARS-COV2 vaccine is a "leaky" vaccine, means vaccinated people still replicate and spread the virus. Armed with this knowledge, look up the Marek Effect and what happened when chickens got vaxxed against the Marek disease with a leaky vaccine.
They are doing this deliberately, hoping to create a strain that will kill the unvaxxed but not harm the vaxxed. Once this superpathological strain arises, everybody really will need the vax, multiple times a year, or they will die.
This is their plan. Absolute control. Truly evil.
