I agree Craig, but the number is 30m+ have the first vaccine and we're moving at a good clip now. Only 2% have the second vaccine, but the trailing data is showing that even one shot is up to 80% effective after 3 wks.
As for the younger people, many have recovered and have some antibodies. How long that's good for is anyone's guess, same as the vaccine. I have a feeling we'll see some sharp overall declines in the US
