I can add to that with some specifics.
In Nova Scotia, we first rolled out vaccine on October 30 and then by November 20, we had made vaccine available to all Nova Scotians. I clearly recall that we were making decisions with our emergency responders well in mind, but we did not include police or firefighters in our previous allotments as we added people to the prioritization list. It was not because they weren't important but, as Dr. Corriveau referred to, our overall priorities were to protect those who were at the greatest risk of getting ill. We needed to preserve the health care system, but we also acknowledged that we were looking to include police and firefighters to protect the community infrastructure as soon as we had sufficient vaccine available.
I do know that if we hadn't obtained enough vaccine to open up immunization to all Nova Scotians by November 20, our next move would have been to add further subgroups, which would have included police and firefighters.
