2019/2020 Universal Influenza Immunization Program (UIIP)

The following provides information about the Ontario Ministry of Health (the ministry's) Universal Influenza Immunization Program (UIIP) for the 2019/2020 influenza season. The UIIP offers influenza vaccine free of charge each year to all individuals six months of age and older who live, work or go to school in Ontario.


Immunization of High-Risk Groups

As in previous years, groups at high risk and those capable of transmitting influenza to them should be immunized as soon as influenza vaccine is available.

Influenza immunization for the general population began on October 30, 2019, the date of the UIIP kick-off.

Individuals in the following three groups are particularly recommended to receive the influenza vaccine as soon as it becomes available:

  1. Individuals at high risk of influenza-related complications or who are more likely to require hospitalization:
    • All pregnant women
    • People who are residents of nursing homes or other chronic care facilities
    • People ≥ 65 years of age
    • All children 6 to 59 months of age
    • Indigenous peoples
    • Adults or children 6 months of age and over with chronic health conditions as follows:
      • cardiac or pulmonary disorders
      • diabetes mellitus or other metabolic disease
      • cancer
      • conditions or taking medication which compromise the immune system (due to underlying disease, therapy or both)
      • renal disease
      • anemia or hemoglobinopathy
      • neurologic or neurodevelopmental conditions
      • morbid obesity (body mass index of ≥ 40)
      • children and adolescents (6 months to 18 years) undergoing treatment with acetylsalicylic acid for long periods
  2. Individuals capable of transmitting influenza to those listed in #1 and/or to infants under 6 months of age:
    • Health care workers and other care providers in facilities and community settings
    • Household contacts (adults and children) of individuals at high risk of influenza related complications
    • Persons who provide care to children ≤ 59 months of age
    • Those who provide services within a closed or relatively closed setting to persons at high risk (e.g., crew on a ship)
  3. Swine and poultry industry workers.
