Illinois day care workers must now have measles vaccine

Illinois day care workers will have to prove they're immune to measles following Gov. Bruce Rauner's signature on a new state law inspired by the suburban measles outbreak this year.

The new law applies to caretakers who work with children six years and younger and takes effect immediately.

"Measles is one of the most preventable diseases," said Senate Republican Leader Christine Radogno. "A majority of the population is vaccinated, but it is our responsibility to look out for young children who cannot receive the full benefits of immunization."

The law says workers must prove vaccination or otherwise show they're immune to measles, tetanus, diphtheria and pertussis.

The suburban measles outbreak earlier this year centered on a Palatine KinderCare. The first case was found there in February, and 15 local cases arose before the end of the outbreak.

State law requires school-aged children to be vaccinated before starting class, with some exceptions. That same requirement doesn't apply to younger children, and infants are too young to be vaccinated, putting them most at risk.

Lawmakers this year also looked at whether Illinois should tighten the exemption that allows children to avoid vaccinations if their parents claim a religious exemption.

Rauner signed the legislation Tuesday without making a public comment.
