NEW HAMPSHIRE (WABC) -- A high school is apologizing for their prom where students and their dates had to display their vaccination status.
The policy was a requirement for the party at a school in New Hampshire.
All unvaccinated partygoers had a mark placed on their hands.
The school superintendent labels it a failed attempt to do contact tracing.
"They fully acknowledge that they should've done a better job of supervising and ensuring that the practices were reasonable," school superintendent David Ryan said.
A review of the event found that marking people's hands may have violated educational and privacy laws.
