On the first question, Health Canada would be more appropriate to answer. I will refer that to one of my colleagues next time.
The second question was on surveillance. I think you are referring to the new pamphlet you received. Various health authorities are sentinels. The sentinels in the field are the health professionals, nurses, doctors, and people working with the public who will observe some of the secondary effects associated with immunization and report back. So it's a bottom-up process.
There are various systems. For example, IMPACT is for children. The Canadian Paediatric Society is contracted to monitor the pediatric hospitals, and so on. They are located in most of the pediatric hospitals and intensive care units. They report to their local provinces or territories and us.
