Health officials push to vaccinate schoolchildren as parents opt out

Vaccine waivers for school-age children are reaching record highs in places, and health officials are worried about damage to herd immunity.

When Idaho had a rare measles outbreak a few months ago, health officials scrambled to keep it from spreading. In the end, 10 people, all in one family, were infected, all unvaccinated.

This time, the state was lucky, said the region’s medical director Dr. Perry Jansen. The family quickly quarantined and the children were already taught at home. The outbreak could have been worse if the kids were in public school, given the state’s low vaccination rates, he said.

In Idaho last year, parents opted out of state-required vaccines for 12% of kids entering kindergarten, the highest rate in the nation.

“We tend to forget that diseases like measles and polio used to kill people,” said Jansen, medical director of the Southwest District Health Department, which handled the outbreak in September.

All states require children to have certain routine vaccines to go to public school, and often private school and day care, to prevent outbreaks of once-common childhood diseases like measles, mumps, whooping cough, chickenpox and polio. All provide exemptions for children who have a medical reason for avoiding the shots. Most also offer waivers for religious beliefs. Fifteen allow a waiver for any personal belief.
