Health committee  I can speak a little bit to vaccine efficacy, in terms of studies that are going to get under way to look at that very question, and perhaps Mr. Griffiths can elaborate on those. But there are plans in place to conduct additional studies to look at populations and their immunogenicity to the vaccine.

Health committee  Madam Chair, given that the agency has increased the number of staff who are working on the pandemic file, I have a history in vaccine safety and so I was asked to come and help out with the vaccine safety section. Unfortunately, Dr. Barbara Law, who is the head of the section, was out of the country and couldn't make it.

Health committee  Yes. It's the vaccine safety section within the Public Health Agency that is going to be looking after the post-market surveillance of vaccine as it's rolled out.
