It is recommended that all individuals aged 6 months or older who live, work or attend school in Ontario receive influenza vaccine.
Influenza vaccine is received in Ontario intermittently in September, October and November, and distributed throughout the influenza season. Initial vaccine supply should be prioritized for the vaccination of people at high risk of influenza-related complications or hospitalization, as outlined by the National Advisory Committee on Immunization (NACI).

Public Health Units began receiving vaccine at the end of September to prepare for distribution to health care providers. Health care providers will begin receiving vaccine supply in early-October for the immunization of high-risk clients. Influenza vaccination for the general population can begin on or after the official launch of the 2017-18 UIIP, which is anticipated in late-October.

Influenza vaccine product mix for the 2017-2018 UIIP

  • TIV - Trivalent Inactivated Vaccine
  • QIV - Quadrivalent Inactivated Vaccine
  • Q-LAIV - Quadrivalent - Live Attenuated Vaccine

Note: As per feedback received by the Public Health Units and health care providers, we have reduced the number of products from 7 to 5 for the 2017-18 season.

Consistent with NACI's recommendation, Ontario continues to offer the quadrivalent flu vaccine (injectable and nasal spray) to children and youth aged 2 to 17 years, as part of the UIIP. The current evidence does not support the preferential use of the nasal spray flu vaccine in children and adolescents 2-17 years of age.
