Seasonal Influenza

Find out where residents can get the flu vaccine in Niagara.

Influenza vaccination is expected to be particularly important with COVID-19 circulating, benefiting individuals, the larger community and the overall health system. Make a strong recommendation for your patients to get the flu shot.

Universal Influenza Immunization Program

Each year, the Ministry of Health provides publicly funded influenza vaccine through the Universal Influenza Immunization Program.

Public Health supports Niagara's health care professionals in implementing this program by providing:

  • A pre-determined, equitable, one time allotment of influenza vaccine for vulnerable and high-risk groups. The exception is agencies and workplaces who receive influenza vaccine based on ordering.
  • The seasonal influenza vaccine order form for health care professionals to order additional vaccine for subsequent orders based on availability
  • Information about influenza vaccine products, supply and distribution
  • Details on local flu activity and surveillance
  • Posters


Call the Vaccine Preventable Disease program Monday to Friday, 8:30 a.m. - 4:30 p.m.

905-688-8248 or 1-888-505-6074 ext. 7396

    Large-scale influenza community vaccination clinics for the general population should be scheduled in November to ensure an adequate supply of vaccine.

    The National Advisory Committee on Immunization indicates that egg allergy is not a contraindication for influenza vaccination and that egg-allergic individuals may be vaccinated against influenza using the full dose of any age-appropriate product.

    Vaccine orders may include both multi-dose vials and pre-filled syringes. Make the necessary room in your vaccine fridge to accommodate the packaging. Pre-filled syringes will require the addition of a 1-inch to 1.5-inch safety-engineered needle tip.

    The recommended needle gauge and lengths for intramuscular injections are:

    Needle recommendation Infants, toddlers and children Adolescents and adults
    Gauge 22 - 25 22 - 25

    Before receiving influenza vaccine, review how to monitor the vaccine fridge temperature and handle a cold chain excursion.

  • Ordering the influenza vaccine

    Primary care

    As a primary care provider, your one time allotment of the publicly funded influenza vaccine is based on the products and quantities that Public Health receives. We aim for an equitable distribution to all health care providers interested in participating in the Universal Influenza Immunization Program.

    After you receive your initial allotment in October, you will be able to order more flu vaccine from Public Health using the seasonal influenza vaccine order form.

    Public Health is unable to take your unused influenza vaccine back to use or redistribute. To help ensure less waste, only order influenza vaccine in amounts that you're certain your office can use. You can order more vaccine as required and as available.


    Public Health doesn't distribute influenza vaccine to pharmacies.

    Pharmacies that have successfully completed the prequalification process need to refer to the Universal Influenza Immunization Program or contact the Ministry of Health for more information, including vaccine ordering, reporting and reimbursement. The Ministry of Health will email all approved pharmacies participating in the Universal Influenza Immunization Program in fall 2022.

    Prequalified facilities

    The Ministry of Health will email all approved vaccine providers participating in the 2022-2023 Universal Influenza Immunization Program. Facilities, such as workplaces, nursing agencies and retirement homes that don't routinely store vaccine, and have successfully completed the pre-qualification process can order from Public Health using the seasonal influenza vaccine order form.

  • Recommended doses and products

    Children six months to under nine years of age not previously immunized with any influenza vaccine in their lifetime are recommended to have two doses at least four weeks apart. It is not necessary to use the same vaccine product for both doses.

    One dose of the influenza vaccine is needed each year to provide protection for all other individuals.

    Don't delay vaccination to wait for a particular product. Seniors are only eligible for one publicly funded influenza vaccination per season.

  • Concomitant administration of influenza and COVID-19 vaccines

    Influenza vaccine can be provided concurrent, before or after any other vaccine, including COVID-19 vaccine.
