I wouldn't say that we do or don't support the development of any vaccine. As I said, there are a number of players. Certainly, vaccine manufacturers and researchers are in the process of trying to develop vaccines for a wide range of infectious diseases, including Lyme, HIV, and so on.
Certainly in the Canadian context, once there are promising results, our colleagues at Health Canada, who are the regulators, would undertake to review the evidence in terms of the safety and quality of any vaccine. If a vaccine were actually to be shown to be safe, have good quality, and be effective, then it would be licensed for use in Canada.
At this point, as Dr. Hawkins has mentioned, we're still waiting. Nothing has come forward.
