@Okiya, predictive models inform planning only but are pretty useless for administrations like those of the UK and US which refuse to grasp the magnitude of the problem, it is a fact that before the "doomsday models" both administrations downplayed Covid19 up until they witnessed the ravaging in Italy then they realized they were on course to lose control, the models have been proven to be inaccurate but were correct in warning that health systems would be overwhelmed without serious social distancing restrictions which the US and the UK took too long to institute. Trump and yourself will claim keeping deaths below the 2million and the recently revised 200k mark is a huge achievement but no it is not,
the Chinese with a population of more than a billion people and have had the virus with them longer than everyone else have been able to keep deaths below the 5000 mark, surely the "best healthcare system" in the most powerful nation on earth should do better, aye?
And on vaccines Bill Gates is right, a vaccine is the best solution but it will take more than one year to have one that works, maybe 2 for mass production and roll out. Containment should have been everyone's priority, it took time but we are all on the same page now.
