Nearly 800 Seattle students will be kept out of school on Wednesday, their first day back after winter break, because they aren't vaccinated against measles.
The move comes after Washington legislators passed a law last year that eliminated parents' personal option to exempt their children from the measles, mumps and rubella vaccine.
Seattle Public Schools started with 7,000 unvaccinated students among approximately 54,000, officials said. After holding a series of free vaccination clinics and sending warning letters to 2,274 students, advising that they'd have to stay home if they weren't vaccinated by Jan. 8, that number fell significantly.
If students can show proof of an upcoming vaccination appointment, they'll be let into school on Wednesday.
"It's also important for our staff, and of course, it's also part of the law," Hoag said.
Students who show up at school today without proof of being vaccinated, or with a medical or religious exemption certificate signed by a health care provider, will be directed to a waiting area until their parents can pick them up.
There were 1,282 cases of measles in the United States last year, according to the Centers for Disease Control and Prevention, the worst year for the infectious disease since 1992.
