Interesting! Would they say that about rabies? Smallpox? Polio? I thought COVID-19 caused clots, myocarditis, hemorrhagic strokes, spike proteins, etc. Isn’t catching this dreaded disease the bane of humanity?
Evidence of efficacy is not enough.
A treatment must be both effective AND safe.
A bullet to the head would be 100% effective in preventing you from dying of covid....it would be effective, but far from safe...
