Days earlier, however, a family had returned from a Greek vacation in the central city of Modiin, a middle-class hub between Tel Aviv and Jerusalem. More than 90 percent of its residents aged 12 and over are vaccinated, according to its mayor, Haim Bibas, making it one of the most vaccinated cities in Israel.
But the family included a child too young to be vaccinated, and who should have spent at least 10 days in home quarantine while awaiting a negative PCR test, according to regulations at the time.
Instead, the parents sent the child to school. Ultimately, around 80 students were infected with the Delta variant.
“The child was not to blame,” Mr Bibas said, indirectly pointing fingers at the parents.
A second outbreak occurred almost simultaneously under similar circumstances at a northern school.
