Hospitals may not give you the right treatment. You may not know enough to ask for it. It may not come at the right time. Different patients react differently to different treatments. If you have respiratory problems already remedial treatments may not work as well for you. And there are more than enough stories of people who thought there were cures available who are dead now. If you are overweight or diabetic or have other comorbidities you are better off getting the shot. Cracks about “mentally retarded” don’t change that.
Look at your own words. The comments there are based on worries of “what if this” and “what if that,” which is a groundwork of fear. This pandemic was not biological, it was psychological. The virus was fear.
As for the common cold coronavirus, the treatments are curative.
They are ivermectin, hydroxychloroquine, vitamin D, zinc, quercetin, vitamin C, NAC, and several others.
If you can cure it, you don’t need a vaccine.
