The New Scientist has warnings from those wot reelly hunderstand pandemics.

And the message is that H1N1 (aka 'flu) has not circulated in anything like numbers this it normally does, because COVID is dominating, maybe out-competing (he said allegorically). So when (not if) it re-surfaces the general public's immunity will have faded and the virus will have mutated beyond the vaccine and that's when we call it a pandemic. OK maybe a small one, but you get the message, it won't be insignificant.

Bill Gates predicted a serious pandemic that would cost the US $2-$3 trillion, 5 years previous to COVID (and the current cost is????)

So should we be asking Bill for another prediction?
