This youtube video:
https://www.youtube.com/watch?... was from a webinar I watched on Tues, first hour is with Dr Osterholm and Sir Jeremy Farr. They talk about herd immunity, Osterholm felt at this point only 5-7.5% of the US had been infected and possibly 15% in NYC, when you need 60-75% for the herd immunity, we have a long way to go without a vaccine.
