This realm and perhaps other dimensions operate by consent. If something is harmful, more than likely the end user will need to sign a contract or go thru some ritualistic agreement before they are allowed to subjected to a negative outcome. The people who have been vaxxed have agreed to put either dead animal and fetuses into their bloodstream or some kind of biotech firmware. And because it's thru the blood, the agreement of consent is much more binding and difficult to get out of.
Notice how these pharmaceutical companies never use the word "cure". They subconsciously (and perhaps some evil higherups, consciously) know that these things are anything but beneficial.
