Thank you very much, Mr. Chair.
My first question is for Dr. Lucas.
This week, we learned that, like Europe, Health Canada is allowing Pfizer-BioNTech vaccine to be stored in the refrigerator at normal temperature for 31 days, whereas so far the recommendations have been to keep it at minus 60 to minus 80 degrees Celsius. That's very good news in itself.
First, I'd like to know what's changed. How is it possible to do that now?
Then, can you tell us how that will accelerate vaccine rollout?
