The Elusive Quest For Herd Immunity
Tuesday, May 11, 2021
During the early stages of the pandemic, many experts considered the threshold for "herd immunity" to be between 60-70% of the population — the point when such a large portion of a community is immune to a disease that it makes spread unlikely.
As of the first week in May, about 57% of American adults have received at least one dose of a COVID-19 vaccine.
Some hurdles are misinformation, while others are simply a matter of access. Still, the United States has a high vaccination rate compared to the rest of the world, while some other countries are experiencing a new wave of infections.
We sit down with experts to understand the elusive goal of herd immunity and all the possible outcomes.
