Thank you, Mr. Chair.
My question is for Professor Fisman. Perhaps Mr. Schabas can express his opinion as well.
We do not yet have a vaccine or antivirals. Serological tests are just beginning. Faced with the desire for reopening, we have suddenly and a little hastily seen the notion of herd immunity appear. But there is no real certainty about the exact data, about the connection between COVID-19 and herd immunity.
Can you tell us where we are at in terms of knowledge or studies on herd immunity with COVID-19? Can you describe the situation?
If reopening were at an ideal rate, would we achieve herd immunity? At what rate would we need to achieve it to make everything safe?
