What is the High School Immunization Program?

Every year, secondary students are offered the Tdap (tetanus, diphtheria and pertussis) vaccination through the school immunization program. Immunization against tetanus, diphtheria and pertussis is required by law for all children attending school in Ontario, unless a valid exemption is filed with the Health Unit.

The Tdap immunization (1 dose, every 10 years) will be offered at all secondary schools beginning February 2024 for all eligible students.

Due to the pandemic disruption, many Algoma youth may be behind for school-related immunizations. Algoma Public Health is working hard to catch students up by offering catch up clinics for all eligible secondary school students who may have missed their Tdap vaccine. If your child is overdue for this immunization, they will be able to receive this vaccine at school immunization clinics.


These vaccinations are publicly-funded under the Ontario’s Routine Immunization Schedule.
