US unlikely to achieve COVID-19 herd immunity, experts say

The United States is unlikely to reach herd immunity as more contagious COVID-19 variants spread and many Americans remain reluctant to get vaccinated, experts now believe.

Instead, the virus — which has killed more than 577,000 nationwide — will only become more manageable, scientists said. “The virus is unlikely to go away,” Rustom Antia, an evolutionary biologist at Emory University in Atlanta, told the New York Times.
