Guest: Dr. Karina Top, pediatrician, vaccine researcher and associate professor at Dalhousie University In what is increasingly being called a pandemic of the unvaccinated, the largest cohort that cannot receive vaccines yet are children under age 12. With the Delta variant spreading rapidly and the fourth wave accelerating, there has been a surge in cases and hospitalizations of children with COVID-19 in the U.S. There are fears something similar could occur in Canada, just as kids go back to school. Experts predict that cases will rise when school starts, but with Canada having one of highest rates of vaccination in the world and the enforcement of other precautions, the goal is to keep kids as safe as possible.
