'Nanobodies' produced by the llama immune system can neutralise the virus that causes COVID-19.
Immunity passports have been touted as a way to reopen the economy. But there are serious concerns they'll create an incentive to intentionally contract the coronavirus.
Early research has pointed to a link between severe illness with COVID-19 and vitamin D deficiency. But there's more to the story.
Immune cells release proteins called cytokines which alert the rest of the immune system that a virus is present.
We blame the coronavirus for the thousands of deaths, but it is actually a hyperactive immune reaction that is the cause of death. An immunologist explains.
Nearly two million antibody tests imported into Australia can't be used to diagnose COVID-19. But it's difficult to make an antibody test that is specific and sensitive enough.
Figuring out how the immune system responds to and defeats coronavirus is our best way out of the pandemic.

Human psychology has evolved to avoid situations that could lead to infection. Behavioral choices now could have long-term effects on how people interact with others and the world.
The science is far from certain, but it appears at least a proportion of people who have had COVID-19 will be protected from another infection – at least initially.

Who is most likely to survive an infection of the new coronavirus? Two immunologists explain that it is those who mount exactly the right immune response – not too weak, not too strong.
Over-activation of the immune system may be behind severe cases of COVID-19.
