The ongoing COVID-19 pandemic has taught us many lessons, including best practices for immunizing populations efficiently. To retain what we have learned, and continue to improve vaccine confidence and uptake, the Canadian population will rely on experts like Dr. Manish Sadarangani to lead robust infectious disease and prevention research. On this episode of SPARK: Conversations, we sat down with Dr. Sadarangani to discuss natural and vaccine immunity to COVID-19, approaches to combatting new variants, and how we can improve vaccine and science communication. We explore the possibility of the COVID-19 vaccine becoming a routine vaccination, and how to best promote the importance of keeping up with those routine childhood immunizations.
