The delta variant has pushed the threshold for herd immunity to well over 80 and potentially approaching 90%, the Infectious Diseases Society of America said in a briefing on Tuesday. That represents a'much higher' bar than the original estimate of 60% to 70%, because delta is twice as transmittedsible and significantly more dangerous than the previous virus, according to the presentation.

Herd immunity is based on the idea that when a certain percentage of the population has been vaccinated against virus or gains immunity by a previous infection, it helps protect the broader population and reduce transmission.

Nearly 60% of Americans have received at least one dose of coronavirus vaccine and about 50% have been fully vaccinated, representing nearly 165 million individuals, according to CDC data. Some 35 million people in the U.S. have tested positive for the virus over the course of the pandemic meanwhile.
