The problem is you are claiming we need to take strong enough action to stop the spread long enough for something like Remdesivir to be proven. I think that is unrealistic and potentially more damaging than the current course.
The headlines are really overplaying this. Saying it had "great success" is simply not true. I am not in the medical field, but I've been on many papers published in scientific journals. The drug may work, but the studies were garbage and in normal circumstance would have no prayer of getting published. They are poorly done with no legitimate controls. On top of it, 25% had severe side effects along the lines of things that people at risk due to underlying medical conditions would likely not tolerate. Don't like my take, here's a more authoritative one:
Here's a quote: ' “The data from this paper are almost uninterpretable,” Stephen Evans, a professor of pharmacoepidemiology at the London School of Hygiene & Tropical Medicine, told Bloomberg. “There is some evidence suggesting efficacy, but we simply do not know what would have happened to these patients had they not been given the drug.”
A realistic assessment of Remdesivir is that with a poorly executed study there is some hope that it might be effective in helping some patients with COVID-19, but the side effects are such that many of those most likely to die from COVID-19 aren't going to be able to tolerate the side effects. Figuring out IF it works and to what extent, who can tolerate it, what dosages, duration, etc. is going to take months. I am hopeful this or something else works, but determining action based on these tests is not sound decision-making.
My opinion is there is a good chance this drug will help some people, but by the time it can be proven and administered, mass exposure to the virus will have already happened unless you start closing down activities to the point that critical supply chains are crippled, mass numbers of people are unemployed, and there could be massive economic damage that leads to major health and safety problems.
