Now when will we be getting the scientific reports on gargling with Clorox and installing interior lighting?
83% were double vaccinated in this study.
What about studies finished before vaccines were available ?
The pandemic had been with us for about a year before vaccines were becoming widely available.
Ventilators were widely used early and poor results reduced their use. I don't remember public health officials saying early that ventilators should not be used because there were no conclusive studies showing effectiveness.
Steroids were used pre-vaccines, with no prior conclusive studies regarding effectiveness.
Azithromycin was an early hope pre-vaccines, but was shown to be ineffective.
The first year of dealing with the Covid pandemic was trial and error.
