You are incorrect on this view. The way hydroxychloroquine works to stop the virus reproducing is not step a virus can 'mutate' to avoid.

Hydroxychloroquine acts as an 'ionophore' to ferry zinc through the cell wall into the cell, where the zinc destroys the RNA / DNA REPRODUCTION STAGE PEVENTING THE VIRUS FROM COMANDEERING THE CELL FOR REPRODUCTION. Viruses must use a living cell to make more virons. The zinc destroys the RNA transfer process.

Not sure what you mean by stable, but could it mean that it does not mutate?

I read that in Iceland they have discovered 40 strains. of the Covid-19 virus

Also I didn't say it would become resistant. Not being a doctor I am thinking about antibiotics and bacteria becoming resistant to them. If that is not the case then good, but I am still wary of doing too much of a good thing, because anything done to access is usually counter-productive.
