Oliver Wyman Predicts COVID Herd Immunity for U.S. by Mid-Summer
March 16, 2021
The U.S. will reach herd immunity threshold when more than 71% of the U.S. population has been exposed to COVID or effectively vaccinated against it, most likely by mid-summer, says a management consultant firm that has been tracking COVID cases.
However, the country will see significant variations by states and must watch out for the potential impact of new variants of SARS-CoV-2, according to Oliver Wyman’s COVID-19 Pandemic Navigator.
States such as New York, New Jersey, Massachusetts, and Rhode Island will reach herd immunity first — as early as the end of May or early June — because these states had the highest levels of infection to date (including detected cases and estimated undetected cases), according to Oliver Wyman’s analysis.
