School Immunization

The Thunder Bay District Health Unit currently provides the following school immunization clinics:

  • Grade 7 Immunizations; as of September 1, 2017 all immunizations are given in Grade 7
  • High School Boosters
  • Because the Immunization of School Pupil’s Act requires the Thunder Bay District Health Unit to keep an updated immunization record (or valid exemption) for every child attending school in the district, children starting school must submit the School Entry Immunization Form (PDF) to the Health Unit. This includes children new to school (e.g. junior kindergarten) as well as children moving to the Thunder Bay District from another jurisdiction.


Elementary School Immunization Clinics

All students in Grade 7 are eligible to receive 3 immunizations to protect against hepatitis B, meningococcal meningitis and HPV. Learn more about the vaccines by visiting Ontario's Routine Immunization Schedule: Grade 7. You can also review Vaccines for Children at School from the Ministry .


Secondary School Immunization Clinics

Most high school students are eligible for Tdap, a three-in-one vaccine. It protects people against tetanus, diphtheria and pertussis.  Immunization against tetanus, diphtheria and pertussis is required by law for all children attending school in Ontario, unless exempted.




Immunization of School Pupils Act

The Immunization of School Pupils Act requires that all students have proof of vaccination against diphtheria, tetanus (lockjaw), polio, measles, mumps and rubella (German measles), meningitis, pertussis (whooping cough), and chickenpox (required for children born in 2010 or later). These infections are covered under Ontario's Routine Immunization Schedule.
