Good podcast by the Smithsonian from a few years ago. Dr Hilleman, whom seems forgotten in history, yet, developed 40 vaccines, 9 still in use today. They have quite many podcasts that I'm liking. We need another Dr. Hilleman now!

If you have Amazon Prime, take a look at The Coming Pandemic, made in 2005. Centered in SE Asia/Thailand, about their readiness for the next big virus. Has quotes from Fauci as a FYI

But the killer viruses seem to come in 50 year increments:
1918: Spanish Flu: worse virus (H1N1) in modern time. 17-100 million dead (50M being used). 500m infected (10% mortality rate). 1.5 billion population. 675k died in the USA. Sad thing is that it killed three age categories evenly: <4 years; 20-40 years; >65 years. Unlike Covid, which is centering >65. Normalized for the 5X population that we have now now, that would be 250 million dead today!!!!!
1968: Hong Kong Flu (H3N2). Killed 1 million people world wide and 100k in the USA. Could have been worse but some people had prior immunity, plus it happened right before the winter 4 week shut down. Again, affected young a lot as well as the very old
2019: Covid 19 ( SARS-CoV-2). 248K Deaths worldwide and almost 69k in USA (so far).
Also, I find this world clock interesting. You can see the population increase (births >> deaths) actively counting. Crazy numbers
