Important updates

Did you recently receive a letter about immunizations required for school attendance?

Halton Region Public Health is sending letters to students in high school who are overdue for immunizations required under the Immunization of School Pupils Act (ISPA).

You may have received a letter because your child:

  • received immunizations that have not been reported to Public Health;
  • is missing a required vaccine; or
  • received vaccines that do not meet the requirements of Ontario's routine immunization schedule.

Please note

  • All immunization records submitted to Public Health are reviewed and processed by staff. Due to a high volume of records being submitted, processing your records may take 4 to 5 weeks or longer.
  • The suspension period for students born in 2006 – 2009 who are missing vaccines or a valid exemption will take place in March 2024. Your child will not be suspended before this time if they are missing vaccines or a valid exemption.
  • Please continue to submit your records to Public Health. You are encouraged to login to ICON to review your child’s record to verify it includes your updates after 4 to 5 weeks, and that there are no additional vaccines required. Thank you for your patience.

School and community immunization clinics

  • Halton Region Public Health is currently visiting schools to offer school immunization clinics. Eligible grade 7 students with parental consent will be offered Meningococcal Conjugate-ACYW-135 (Men-C-ACYW), Human Papillomavirus (HPV) 9-valent and Hepatitis B (HB) vaccines.
  • The community immunization clinics for students in grades 7 through 12 that are scheduled from Monday, December 18 to Friday, December 22, 2023 are fully booked. Limited walk-ins will be accepted.
  • The community immunization clinics for students in grades 9 through 12 on Thursday, January 25 to Friday, January 26 and Monday, January 29 to Friday, February 2, 2024 are fully booked. Additional appointments will be released in January.
  • Students in grades 7 and 8 can receive school-based vaccines during school immunization clinics from April to June 2024, and at community immunization clinics that will be scheduled in June 2024.
  • Additional community immunization clinics are being planned for early 2024 and will take place before the ISPA suspension period begins in March. Please check back regularly to book an appointment at a community immunization clinic in early 2024.
