As usual, great interview. Thanks! One thing that had me thinking. Jay mentions an initial IFR of 0.2% on average in the US (pre vaccines, not omicron) with 50 year olds at that rate and with the rate increasing for older people and decreasing for younger people. Quick back of the envelope calculation: US population 330 million, IFR=0.2%; if every american would get it that would mean 660,000 deaths which is below the official US number of 873k. Either numbers are overblown or vaccines were of little help (or a little of both). Comments?
