Epidemiologist Professor Mary-Louise McLaws speaks with Amy about how Australia can reach herd immunity against COVID-19 and when children should be vaccinated against the virus. She also discusses the Delta variant outbreaks, how the variant "behaves" and transmits, and the need for clear lockdown rules and tough restrictions. Plus, the reality of Long COVID in children and adults, and whether we will ever be able to treat this virus “like the flu,” as the Prime Minister suggests.

Mary-Louise is a member of the WHO’s Advisory Panel for Infection, Prevention and Control Preparedness and Response to COVID-19.
