Co-payments to improve access to unfunded vaccines at community pharmacies

Inclusion Criteria:

* Community Pharmacy Sites: Inclusion criteria for the selection of the community pharmacies will include volume of prescriptions (e.g., how busy the site it), stable pharmacy patients (e.g., patients who consistently use the same pharmacy), availability and interest of community pharmacies and community pharmacy professionals, sufficient numbers of pharmacy professionals qualified to provide vaccinations, and lack of substantial health care spill over to adjacent communities. Spill over is defined as a pattern of health-care utilization where the public regularly receive care at different regional health centres. Communities will be geographically separated to minimize potential spill over. Based on this inclusion criteria, one pharmacy from the four health zones in Nova Scotia will be selected to implement the co-payment model within their community pharmacy, while a mix of urban and rural pharmacies in Ontario will be selected to implement the co-payment model.
* Members of the Public: The participating pilot pharmacies will recruit through targeted screening members of the public who meet the vaccine-specific eligibility criteria or their substitute decision-makers for those who lack capacity to consent. Any members of the public or the substitute decision-maker who consents to participate will be eligible until the maximum number of participants we aim to recruit has been achieved. Eligible members of the public will receive the vaccines based on NACI recommendations for each product as part of routine care.
* Recommended but Unfunded Vaccines: FluMist Quadrivalent: An age-appropriate quadrivalent influenza should be used in children (2 to 17 years) without contraindications or precautions; Shingrix Vaccine: Adults 50 to 64 years of age in Nova Scotia or 50 years of age or older in Ontario without contraindications or adults 18 years of age or older if immunocompromised; and Abrysvo or Arexvy (RSV) vaccine: Adults 50 years of age or older (Arexvy) or 60 years of age and older (Abrysvo) who are at increased risk of severe RSV disease. Note: The eligibility criteria for each vaccine product may be revised during the pilot study if there are any changes in vaccine recommendations and/or funding status in Nova Scotia or Ontario.

Exclusion Criteria:

* FluMist Quadrivalent: should not be used in children or adolescents for whom it is contraindicated or for whom there are warnings and precautions; should not be used in children or adolescents already adequately immunized against influenza; not recommended for pregnant individuals, health care workers, and adult 18 to 59 years old with specific chronic health conditions; adults 60 to 64 and 65 years and old, as this vaccine is not authorized for use in these age groups; pediatric children (2 to 17 years) of the participating pharmacies who already have private insurance coverage to cover all (or most) of the FluMist vaccine will be excluded from taking part in this study.
* Shingrix: Persons with active herpes zoster (HZ) should not be immunized with HZ vaccine; should not be used in individuals already adequately immunized against HZ; adults 65 years of age or older in Nova Scotia, as this vaccine is publicly funded for this age group; adults 65 to 70 years of age in Ontario, as this vaccine is publicly funded for this age group; and adults (50 to 64 years old in Nova Scotia and 50 years of age or older in Ontario) of the participating pharmacies who already have private insurance coverage to cover all (or most) of the Shingrix vaccine will be excluded from taking part in this study.
