Thank you, Mr. Speaker. I appreciate the opportunity to talk about this issue, because it is one that I have heard discussed quite often. The Chief Public Health Officer is the staff person who is ultimately responsible, but she doesn't work in a vacuum. She works with colleagues across the country. She works with colleagues in her office. She regularly consults community and Indigenous leaders. She also receives advice from the National Advisory Committee on Immunization. She uses a variety of information sources to look at the decisions she makes about priority groups for vaccination and, as has emerged recently, the timing of second doses based on the supply interruption by the manufacturer. Thank you.
