2016-17 Immunization of School Children in Halton Report

Purpose of the Report

The purpose of this report is to provide information about the percentage of Halton school children aged 7 or 8 (born in 2009) or aged 16 or 17 (born in 2000) who were compliant with the Immunization of School Pupils Act (ISPA) by the end of the 2016-17 school year. The report also provides information about the percentage of Halton school children aged 12 or 13 (born in 2004) who completed the vaccination series for three school-based vaccines by the end of the 2016-17 school year.

Background

Immunization is one of the best ways to protect our community from vaccine-preventable diseases. The Immunization of School Pupils Act (ISPA) requires Ontario students attending school to be immunized against diphtheria, tetanus, polio, measles, mumps, rubella, pertussis, and meningococcal disease. Children born in 2010 or later must also be vaccinated against varicella. Additionally, the Ministry of Health and Long-Term Care mandates public health units to offer free vaccination against meningococcal disease, human papillomavirus (HPV), and hepatitis B to all grade 7 students free of charge.

This report uses data from Panorama, a provincial database used to maintain vaccine records in Ontario.
