Students kept out of schools in Greece by parents who refuse to abide by COVID-19 health measures could find themselves held back a year and have to repeat the grade.

A reported 35 of them in the central city of Larissa face those consequences because of their anti-vaxxer parents who won’t provide school authorities with required negative tests either, said Kathimerini.

That has led to the students being barred from going into the schools and officials warning it means they could be held back, school administrators said to have contacted the parents to inform them it would happen if the students go past a permissible number of absences.

There are approximately 10 high school and middle school students, with the remaining 25 being in elementary school, the paper said, but no word on whether the parents would comply.
