There are about 70 companies working on COVID vaccines.
There are many companies, universities, and Federal labs experimenting with drugs for treatments.
It might be useful to assemble a list of the drugs/companies we are familiar with.
The drugs most often mentioned are:
anti-malarials like chloroquine/hydroxychloroquine (Sanofi and generics); Remdesivir (Gilead).
Some of us here are familiar with IPIX's experimental drug Brilacidin, which is an antibiotic and anti-inflammatory, recently found to have anti-viral activity.
Many other companies are looking at their anti-inflammatory drugs to see if they can stop the catastrophic "cytokine storm" -- the body's immune response which, when it becomes too active, can cause multiple organ failure and kill people.
Short article about cytokine storm:
Also, two companies, Cytosorbents (CTSO) and Arch Therapeutics (ARTH), have filters which can remove toxicities from the blood, to treat cytokine storm. ARTH has a CE mark (Europe) but is not approved in the U.S.
