I think it's not so much about the knowledge of vaccination and the vaccination protocol as the data flowing, in terms of surveillance of individuals post vaccination.
There needs to be a pan-Canadian repository for this. The data needs to be collected on a consistent basis, provided by provincial governments to the federal government, so that you can do surveillance at a pan-Canadian level. This could have been part of the arrangement made with the provinces as part of the deal in which the federal government paid in full for the vaccine. In the past, it has paid part of the cost but not the full cost. This would have allowed for surveillance across provincial boundaries. This disease is not limited to one provincial jurisdiction.
