Preventable Disease, Vaccine

The goal of this pilot demonstration and evaluation project is to determine the acceptability and feasibility of a co-payment model among the public and providers and assess whether a co-payment model in community pharmacies in Nova Scotia and Ontario increases the accessibility and uptake of recommended but unfunded vaccines. The research questions that guided the development of this study are: * What is the feasibility of implementing a co-payment model for recommended but unfunded vaccines in community pharmacies? * To what extent is a co-payment model for recommended but unfunded vaccines perceived as acceptable to community pharmacists and the public? A co-payment model will be piloted at a maximum of 8 select community pharmacy sites in Nova Scotia (n=4 sites) and Ontario (n=4 sites). Each community pharmacy site will be randomly assigned to pilot one of the steps of the co-payment model for the duration of the demonstration project. At the end of the pilot study, participating pharmacy providers will be asked to complete an online survey about their experiences in implementing the co-payment model into their pharmacy. As part of the co-payment model, recruited members of the public (participants) will choose to receive the vaccine (if eligible) at a reduced cost either for themselves or their dependent (e.g., incapable minor or adult), as part of routine care (following standard pharmacy practice). After receiving the vaccine, the participant will complete an online survey exploring their thoughts on the co-payment model, their satisfaction with the co-payment model, their perception on vaccines in general, and their demographics (such as gender, age, education, race/ethnicity).

This prospective cohort study aims to provide the evidence-based clinical guide to help decide the revaccination doses of hepatitis B vaccine that the high-risk young adults without hepatitis B seroprotective antibodies (anti-HBs titer\<10 mIU/mL) need to take.
