Israel has extended its Covid-19 vaccine passport system to children who aren’t yet eligible to be inoculated, allowing them to visit cinemas, restaurants and other entertainment businesses as it continues to reopen its economy. Under the program, children with negative PCR tests will be eligible for a three-day so-called green passport that will be associated with their parents’ passes. The passports take the form of a QR code that can be carried on a smartphone, though their use isn’t always enforced. Religious-affairs ministry officials had stipulated that only those carrying a green passport could attend a religious festival on Thursday at Mount Meron, where dozens of people were killed in a stampede, but health officials had said it would be impossible to check the status of those attending.
