The Rochester School District says 71 students failed to provide documentation that shows they received their vaccines.

Rochester Public School Board members voted last week to enforce a state law that requires students be immunized or be officially exempt for reasons such as health or religion.

Students had to submit the proper paperwork to the school district in order to prove they are exempt by Wednesday.

The Rochester School district said the decision to prohibit students from attending class that did not have official documentation that they received their vaccines is simply enforcing a state law.

Some of the vaccines required by the state of Minnesota Include measles, mumps, chicken pox and tetanus.
