Scientists think face masks help limit virus spread by protecting everyone else from the infected wearer. As a result, face masks are now mandatory in many cities, states and countries to limit the spread of COVID-19.
Some new studies have found people who were never symptomatic, exposed to, or tested positive for COVID-19 that have immune cells that can recognise COVID-19.
Instead of protecting us from the virus that causes COVID-19, the body's natural defence mechanisms can overreact and inflict damage. Understanding why could make the infection far less dangerous.
A mission to reprogram innate immunity to combat inflammatory and infectious diseases has been supported by the National Health and Medical Research Council.
Ian Henderson, Professor of Microbiology, and Dr Larisa Labzin, Virologist, discuss COVID-19 – immunity, vaccine development, epidemiology and what we do and don’t know.
