But what you are arguing, without perhaps realizing it, is simply for evidence that any
ionophore combined with zinc, may be protective, and broadly so in relationship to many viruses. And that may be quite true in COVID19, although the RCT proof is still absent. But let's presume that it's still true. There is a HUGE catch in all this. For example, Quercetin, EGCG (principal polyphenolic in green tea) and several other compounds may promote this effect WITHOUT REMOTELY THE TOXICITY OF HCQ!! The benefit you are mentally accruing to HCQ may be therefore in some sense unmerited.
While we are on the subject of protection, keeping Vit D levels above 30 and probably even above 40 may have significant effects in terms of buffering disease severity and may explain some of the vulnerability of dark skinned individuals, and ironically Spain and Italy where vitamin D deficiency is more widespread, whereas there is more supplementation of vitamin D in northern latitude European countries which have shown significantly less mortality per capita. This is an example of a protective strategy that has far fewer downsides also then hydroxychloroquine and other upsides as well. In that sense it meets an optimal standard in terms of risk/benefit ratio meaning close to zero risk and possible to probable substantial benefits. We know from lots of other research that vitamin D buffers severity in relationship to other respiratory illnesses, and for folks looking for the latest on this see

I appreciate that you're trying to think prophylactically and in terms of various bioprotective strategies. Here is one (Supplementation with vitamin D, quercetin, EGCG and zinc) with far better dividends In terms of overall risk-benefit ratio than hydroxychloroquine.
