The Huron County Health Unit is issuing an urgent appeal to parents to have their children immunized by May 8th, or their kids will be suspended from attending school.
Public Health Nurse Christina Taylor says as many as 400 children across the County have yet to receive their shots against a variety of illnesses.
Vaccination notices were sent to parents in January and March.
Under provincial law, students must be vaccinated against diphtheria, tetanus, polio, measles, mumps and rubella.
Taylor says last year, vaccines for meningitis and whooping cough were added to the list, as well as chickenpox vaccine for students born in 2010 or later.
She mentions the spike in the number of unvaccinated Huron County children happened since those immunization requirements came into force.
Taylor tells Bayshore Broadcasting News suspension notices will be sent out on May 8th, with the suspensions to take effect on May 26th.
She cautions that if Avon-Maitland or Huron-Perth Catholic elementary teachers are on strike by then, the Health Unit will impose the suspensions at a later date.
Taylor asks parents of children who don't have their shots to contact the Health Unit by phone or e-mail, and public health staff will work with them to get their kids immunized.
