An outbreak of the Delta variant of COVID-19 in Israel has spread to some vaccinated people — with about half of the adults infected fully inoculated with the Pfizer shot, a health official said. Ran Balicer, who heads a COVID-19 government advisory committee, said that about 90 percent of new infections in the country were likely caused by the Delta variant, a highly-contagious strain that first emerged in India, the Wall Street Journal reported. “The entrance of the Delta variant has changed the transmission dynamics,” Balicer said.
