I think your sentiment is shared by those of us who refuse to get the shot. The future ramifications of injecting billions of spike proteins into your body is yet to be seen. Just know we (so called "anti-vaxxers"--even though it isn't a "vax") will just as passively dismiss those who suffer from the jab now or in the future.
Alternatively we know some of the future ramifications of having the genuine article spike protein in your body.
And they are not injected, btw, we make them. The mrna and j/j vaccines inject a recipe.
