According to the US Centers for Disease Control and Prevention (CDC), an estimated 34 percent proportion of the US population already has some immunity to the virus from having been exposed to the virus.

As per sources who told a leading international daily, it reads - With nearly 100 million Americans fully vaccinated and new coronavirus cases at their lowest level since last October, the US might have attained or will reach the crucial inflection point, the media reported.

While some researchers argue it's still too soon to say, a growing number of epidemiologists, infectious disease researchers and public health experts think that the vaccination campaign may be helping the country win the race against the coronavirus, according to a report in NPR.org.

"I think we've hit a tipping point. We've really turned a corner on this latest wave. And I think that the worst days of the pandemic really are now behind us," Ashish Jha, the dean of the Brown University School of Public Health, was quoted as saying.

Added to this is the vaccination campaign, the report said. More than 43 percent of the population has now gotten at least one shot, and a third are fully vaccinated. That's getting very close to where other countries, such as Israel, started to turn the corner and experience a precipitous drop in infections, it added.
