Professor Nadav Davidovitch, a senior official in the Israeli Association of Public Health Physicians, told Reshet Bet radio in an interview on Sunday evening, "From studies and follow-up of those who have been vaccinated against coronavirus, it seems that immunity is valid for longer than we thought. We may extend the green passport for those who have been vaccinated beyond six months."
He added that "Israel is buying vaccines in case a third vaccine is required, at the moment it is not required."
