TEL AVIV, Israel—In the race to herd immunity, Israel has three things that put it well ahead of other countries: a relatively small population, an ample supply of the COVID-19 vaccine, and a centralized health care system that coordinates the complicated logistics of distribution.
These advantages have put Israel at the top of the world vaccination chart, with over 30 percent of the population of 9.3 million having already received the required two doses. In the United States, by comparison, the number is about 4 percent.
