RE: Because zinc may not be essential. Do your homework about how HCQ alone inhibits viral penetration of cells and mitigates immune response.
The first large scale study made by the French Doctor, Didier Raoult, which actually succeeded in over 91% of patients only used Hydroxychloroquine and Azithromycin.
It was Dr. Zelenko who recommended its use.
But there is also one essential condition that will make or break the clinical trial -— WHEN these cocktail is administered.
If the NIH only chooses patients who are WAY ADVANCeD in their disease, i.e., in ICU or in the hospital ( what the VA study and other studies did ), the results will again be MIXED.
All successful cases applied the cocktail EARLY in the patient’s disease ( within 5 days of positive tests and/or manifestation of Covid-19 symptoms ).
Dr. Zelenko’s intent is to PREVENT hospitalization.
It is very difficult to ascertain the effect of any intervention when multiple factors are involved. All good studies have to control what interventions are used to single out any effect by one specific agent. Using two agents is bad enough. 3 agents...really gonna confuse the situation. Have you spoken to anyone who could set up a study such as you envision? Have you written a proposal to anyone...maybe zinc sulfate tablet manufacturers might pony up the cash. Go for it.
