Today, Public Health Ontario (PHO) released their Immunization Coverage Report for School Pupils in Ontario for the 2017–18 school year.  This report highlights the percentage of school-aged children who are adequately immunized against specific vaccine-preventable diseases (VPD) at a point in time.

The Immunization of School Pupils Act (ISPA) requires that students attending primary and secondary school be immunized against nine vaccine preventable diseases including, measles, mumps, rubella, diphtheria, tetanus, polio, pertussis, meningococcal disease, and varicella, or have a valid exemption on file with the health unit.

Immunization coverage rates in Windsor and Essex County (WEC) have steadily improved since the 2015-16 school year when the health unit increased resources to assess immunization records of Grade2 students and implemented the suspension process for incomplete records. PHO’s 2017-18 report shows that immunization coverage rates for students in WEC for all ISPA-required vaccines were similar to or higher than Ontario.

Key findings for WEC reported for the 2017-18 school year include:

  • Coverage in 7-year olds for all ISPA-required vaccines
    • Measles (90.9%); Mumps (90.9%); Rubella (96.8%)
    • Diptheria (88.4%); Tetanus (88.4%); Polio (89.3%)
    • Pertussis (88.3%); Meningococcal disease (96.3%); Varicella (87.1%)
  • Coverage in 12-year olds for meningococcal disease (82.9%)
  • Coverage in 17-year olds for ISPA-required vaccines
    • Measles (97.2%); Mumps (96.9%): Rubella (98.6%)
    • Diptheria (81.3%); Tetanus (81.3%); Polio (94.2%)
    • Pertussis (79.6%)

Windsor-Essex County Health Unit’s Medical Officer of Health, Dr. Wajid Ahmed says, “This annual report serves as a good reminder that although we have seen improvements in our vaccination rates, there is still important work to be done to ensure our community is protected from the spread of vaccine preventable diseases.”
