When it comes to COVID-19, why do some infected children become severely ill while others have no symptoms at all? Why does the virus tend to hit adults harder than kids? And what role do little ones play in spreading the virus? Those are the mysteries Alberta researchers hope to help solve with a new study out of the University of Calgary.  Researcher and professor Dr. Jim Kellner joins us to talk about the project. We also look at the science and art of building your bubble. As restrictions continue to ease across the country, what does that mean for cohort or bubble families? Nova Scotia’s Heather Laura Clarke is sticking to just one bubble family. She joins us to talk about how it’s working for her family and if and when they will expand.
