It's its not a vaccine It's more akin to stimulating an allergic reaction. They program cells to produce Glycoproteins which the body reacts to be producing its own Glycoproteins to tag or bind to the invaders. Then should the real virus appear the spike proteins. Glycoproteins. Get tagged or bound by the bodies Glycoproteins. Antibodies. Do that the virus cannot bind and enter our cells. It also bypasses normal immune system. It's like pulling a single wire instead of running a complex electronic device. Cool trick bruh but not actual health science and no one knows all the outcomes of it
