As coronavirus deaths fall to the single digits in Israel and the United Kingdom, the possibility arises that the vaccination rate required to reach herd immunity might be much, much lower than scientists earlier believed. The United States might even be close to reaching it, but only if we can convince another 10% to 20% of the U.S. population to go get the jab.

Some of those still unvaccinated are just the standard anti-vaxxer conspiracy theorists, and these are probably a lost cause. But a significant number are simply not eager to get the vaccine, or they are on the fence due to the unprecedented speed of the vaccine’s production.
