Best I can tell, the IFR estimates have been stable since late June in that 0.64-0.66% range. Certainly not smallpox by any means, but also not trivial. Definitely glad to hear treatments are continuing to improve. My hope is always to preserve lives. I know there are a few new drugs under investigation as possible treatments as well and hopefully one or more of those help save some lives.
Ultimately, I think this all ends with one or more safe and effective vaccines deployed. It seems President Trump agrees as he’s poured a lot of money and effort into that route. And I think it was a brilliant move to finance production of candidates parallel to the phase 3 clinical trials. That alone will save months, and that means lives (about 20,000 - 30,000 per month).
You have more hope in a vaccine than I do. I suspect this will end up
combined with the yearly influenza vaccine and about as effective. No the fatality rate is not trivial people do die from it but so far what I have seen is on par with H1N1. a retaining nothing to inspire mass panic and economic suicide.
