OTTAWA — Canada is planning for what’s poised to be its largest-ever vaccination campaign. 

In a few weeks, the Public Health Agency of Canada (PHAC) is expected to release an interim statement listing which priority groups should get first access to an authorized COVID-19 vaccine, when one or many become available.

Dr. Caroline Quach-Thanh is the chair of the National Advisory Committee on Immunization (NACI), the external advisory group responsible for identifying which groups should get COVID-19 vaccine priority. This sort of triage is necessary and similar to how the H1N1 vaccine was first rolled out. 

“Of course the problem currently is we don’t know which vaccine is going to be available and how many doses,” Quach-Thanh told HuffPost Canada.
