Chloroquine & Zinc is the effective combo. From what I've heard chloroquine helps zinc get into the cell. Then zinc inhibits the replication of the virus inside the infected cell. Look it up.

Too bad there is a shortage of chloroquine drugs at this moment.

There's no shortage of chloroquine, it's a molecule in public domain and it's not hard to synthetize

The fact is that useless for this virus.The COVID-19 main problem is how our immune system react to the infection. A small virus load is enough for somebodies, so reducing virus load help only people who yet have no problem to deal with it

A lack of zinc weaken the immune system, but more zinc change nothing (you literaly sweat it)

According to some media outlets there is shortage of chloroquine at the moment, at least in my country. Many countries are trying to buy the drug at the same time.

I'm aware that we still need a vaccine to tackle the pandemic. The chloroquine is not the magic definitive solution.
