Stock Photo - 07 June 2021, Baden-Wuerttemberg, Heitersheim: Pupils sit in class on Monday morning while a teacher stands in front of the blackboard next to open windows. They are all back at St John's Secondary School for the first day of school after the Whitsun holidays. After nearly half a year of home schooling, hundreds of thousands of students in the Southwest can return to the classroom. The reason is the falling incidence of corona and the vaccination of almost all teachers.
