More than 200 students in Buffalo can't and haven't been to school for the last month because they aren't up to date on their vaccines.

As of Wednesday, 256 Buffalo Public School kids were still at home. The number is down from about 5,000 at the start of the school year.

District officials said it's in large part because of new state legislation that removes non-medical exemptions from school vaccine requirements. The law requires students to have their first dose of vaccines 14 days after the start of school, which was September 20.

Officials previously said they've provided families a list of clinics where kids can get immunized. In the meantime, teachers have been sending homework to the students who can't attend school.
