Israeli health officials are returning to mask mandates at indoor facilities following a small spate of positive COVID Delta variant cases in adults who had been fully vaccinated with Pfizer's coronavirus vaccine. That is, these adults had received two doses of the vaccine, and it had been two weeks since their second dose, the generally accepted timeline for full vaccination.
The Delta variant has rapidly become the main source of new COVID cases in certain parts of the globe including India and the U.K. It also makes up an increasing share of new cases in the U.S., clustered in states with low vaccination rates. The mutation, originally identified in India, appears to be far more transmissible than the novel coronavirus and could be a particular threat to younger people.
In Israel, expert advisers to the government estimate that about 90% of new cases are linked to the Delta variant, according to the Wall Street Journal. About half of the Delta variant cases examined by experts occurred in children under the age of 16 who haven't been vaccinated. But about half of adults who were infected in this outbreak were fully immunized with the COVID vaccine.
