My love for calculators (and slide rules!) is to blame for my lifelong fascination with computation, and the varied career path that has taken me on, much of which can be measured by the calculators and computers encountered along the way, from JOSS, to a high school IBM 5100, to jobs as a software architect and digital executive.
I guess many of us are running their own individual modelings. One challenge is to derive an estimate for the dark figure of infected persons. This is a hugely varying factor between countries depending on when testing started, how intense, transportation and evaluation times, etc. It can roughly be calculated using the more reliable mortality numbers and parameters like mortality rate (latest is 1.4% according to Leung, Wu, Leung et al.) and duration of illness.
Either way, it is horrifying.

As I wrote in many forums, there was a SARS epidemic and the big medicine manufacturers do nothing to develop the vaccine. There are lots of papers and books about this, like this book: Coronavirus Replication and Reverse Genetics.
Just read the back cover text: "This book contains information on virus genome structure, mechanism of replication and transcription, and the development of tools that make possible reverse genetic studies to understand virus-host interactions and the molecular basis of virus pathogenesis. The book also provides essential information for the development of classical and recombinant vaccines to control coronavirus infections."
This book published in 2005.
Why these big companies do nothing during the last 15 years? Because the profit was too small. That's it. Maybe during these days, this will be more profitable.
I had read the book, "The Wisdom of Crowds", but I am not convinced.
It is likely the author already believed in wisdom of crowds, before citing examples.

But, if no one is worried, that's when you should worry
During the 2002-2003 SARS outbreak it took about 20 months to develop a vaccine. The vaccine was never made commercially available due to the effective containment of the SARS virus.
Even if a vaccine makes it through all the rounds of testing, it’s unlikely that drugmakers can manufacture enough vaccine to protect everyone who might be exposed to the virus.
Moderna, which currently has the largest manufacturing capacity of the three CEPI-funded groups, thinks it could produce 100 million doses in a year, for the current COVID-19 virus, according to Science. That means health officials would need to prioritize who gets the vaccine. This is based on factors like who would have the most severe symptoms and who is most likely to spread the virus.
It appears that a COVID-19 vaccine, for the general population, will not be available in the immediate future.
