Peel Public Health publishes new report on estimated school immunization rates

The Region of Peel – Public Health has released the new Immunization of School Pupils Act: Estimated Coverage & Non-Medical Exemption Rates, By School report. The report details estimated coverage rates for Measles, Mumps and Rubella (MMR) immunizations and Diphtheria, Tetanus and Polio (DTP) immunizations across Peel schools.

“What the data shows us is that the vast majority of students in Peel are up-to-date on these crucial vaccinations,” said Dr Lawrence Loh, Associate Medical Officer of Health for the Region of Peel.

Based on this data, the average estimated coverage in Peel schools is 94.6% for measles, mumps and rubella and 90.8% for diphtheria, tetanus and polio. Slightly lower rates for diphtheria, tetanus and polio are attributable to the additional vaccine dose required for diphtheria and tetanus in adolescence.

The average non-medical exemption rate for MMR and for DTP across Peel schools is 1.8%.

Data in the report is an estimate of the proportion of students that complied with requirements in the Immunization of School Pupils Act. Notably, such school-based estimates of coverage do not reliably approximate school population coverage rates for the following reasons:

  • they are estimates for two aggregate groupings of diseases
  • reporting information is collected on an ongoing basis and fluctuates throughout the year
  • reported data only tracks students born between 2001 – 2011 (ages 7-17)

This is the first year the Region of Peel – Public Health has analyzed and published school-level immunization data. Staff will work with the school boards to review the benefits of collecting and sharing this data in the future.
