>>It's not that clear that a lockdown helps. NY closed the earliest in the US but was the hardest hit nevertheless. It has now mostly reopened and cases aren't going up. Chances are we may have reached herd immunity there.

No, this is absolutely wrong, every single sentence. Lockdowns definitely help. New York was hit hardest because, despite closing the earliest, they still closed way too late. Cuomo resisted calls from his health experts for almost three weeks. By the time he gave the order, there were 5,000 daily cases reported and the virus was practically out of control.

New York doesn't have herd immunity - not even close. Majority of New Yorkers were not infected. https://patch.com/new-york/new-york-city/nyc-hasnt-built-her...
