Vaccine passports: Necessity or false sense of security? Freedom or inequality?

Guest: Alex Boyd, Star Reporter based in Calgary, who has been focusing on vaccines. As more and more vaccines get into arms in Canada, the thorny issues of how to denote people's vaccination status has become a topic of discussion. There are already several countries using some form of vaccine passport to enable easier travel. However, they are leading to another set of issues including questions of privacy, equality and if a passport would be a false sense of security when we don't know for sure that a vaccine stops transmission. There are also several practical issues as to how they might work. Will they be something we see in Canada? Are they what the world needs to jump-start economies and restart travel and tourism? We discuss how they are being used so far and what worries experts and bioethicists if they become commonplace around the world.
