And note that is at about 60% *of adults only* having first dose. Israel is largely open and unrestricted now too. That hints at my past observation: Around 30%, the growth rate starts to slow, and around 50%, it really starts to drop. The above suggests 60+% is getting close to so called herd immunity, it seems.
I read a forecast that the U.S. will reach 60% fully vaccinated (two doses) by July 1.
Real world data suggests the U.S. might already have 50+% immunity when natural immunity is included (from prior infections).
This all seems like very good news.
