Here's what I been looking at some today. I guess from what I am gathering...am I am not in the medical field, is that interferon and hydroxychloroquine along with the antibiotic are used to break the cellar membrane to allow zine to access the cell. They act as an ionophore. Zinc inside cells stops replications of the virus but you have to have an ionophore to get zinc to be inter-cellar.

I did some looking up what ionophore meant,

ionophore [i´on-o-for″]
any molecule, as of a drug, that increases the permeability of cell membranes to a specific ion.

i·on·o·phore (ī-on'ō-fōr),
A compound or substance that forms a complex with an ion and transports it across a membrane.
[ion + G. phore, a bearer]

ionophore (ī-ŏn′ə-fôr)
n.
A compound that facilitates the transport of ions across a cell membrane, either by binding with the ion or by creating a channel through the membrane.

I looked at other articles on ionophores, I ran across words like quercertin and epigallocatechin which are used as natural ways to enhance introduction into a cell. There is some zinc inside cells naturally just not enough to ward off the replicating virus, we gain that zinc through foods we eat and we also naturally consume quercertin through certain foods we eat, quercertin also comes in a tablet form but they don't recommend taking more than 500 to 1000 mg a day, so you could increase your zinc intake and more of it would get into your cells by taking it or eating more foods that have it. Epigallocatechin on the other hand they do not recommend you take any amount in a tablet or power form without a doctors permission but it is found in abundance in green tea.
