Schools in the United States are largely expected to return to full-time, in-person instruction this fall.

Many colleges will require proof of vaccination.

The COVID-19 vaccines haven’t been approved for all school-aged children – only those 12 and older.

Clinical trials are underway for those younger than 12 and the vaccines may be approved by the time school starts again this September.

That is raising questions about whether K-12 schools will require proof of vaccination as well.
