The Big Pharma machine simply wasn't incapacitating humans at a fast enough rate, so the vaccine industrial complex, along with Bill Gates and Anthony Fauci at the helm, designed a "microwave" version of injected illness the likes of which the world has never seen.
Most people who believe in vaccines still don't know about deadly mercury, squalene, circovirus, aborted human fetal cells or toxic spike proteins
Mercury has been used for decades in people's dental fillings and in the multi-dose influenza vaccines (a.k.a. flu shots) to lower overall intelligence and critical thinking, just like the fluoride purposely put in municipal tap water. This alone is enough to keep people from discussing toxins in water, medicine and food to the level they need to realize what is happening to them.
