About 90 children at Stevensville Elementary School in Montana have started a series of six shots of anti-rabies vaccine after a local schoolmom gave show-and-tell-and-touch presentations in five classrooms involving a dead bat.

The bat was subsequently confirmed to be diseased.

School officials say they will use liability insurance to pay up to $70,000 for the exposed children to be vaccinated. The overall cost could surpass $150,000.

The school has since set a policy requiring that anyone visiting the school obtain a visitor pass.
