“China and Russia have their own vaccines. Far less effective than Pfizer.
They are competitors and would live to show any faults in an American vaccine.
But they found none.”
Your claims are based on assumptions with high potential error.
You cannot be certain the vaccine doesn’t contain graphene oxide.
There are claims that the substance was omitted from patent documentation because it’s a known toxin.
Given the history of pharmaceutical crimes proven in court, it’s a lot safer to assume the vaccines have toxins.
I can be certain for the simple reason that the vaccine is out there and labs across the world can test it and have tested it and found no graphene oxide.
