Seven teachers at Pukekohe High School haven't been able to confirm they've had the measles jab

The southern Auckland school's shut for classes today - after a student's been confirmed with the disease... and not enough staff were left to run the school.

Principal Richard Barnett won't say if any staff are anti-vaxxers - but he says they're advising staff to get the shot as soon as possible.

It's also possible staff could be immuno-suppressed and unable to be vaccinated, or may not be able to dig up the paperwork saying they've had both MMR shots.
