The fact that the rate of new vaccinations has slowed considerably in Israel gives us a unique look at Western(ish) nation at 50% fully vaccinated. The rate of new cases completely cratered as they approached that 50% mark and has stayed low and steady as the rate of new vaccinations has slowed.

We might hit that same benchmark in the US by the end of this month, but we'll likely glide right past 50% since supply isn't expected to be an impediment.
