We’re cleaning and washing our hands perhaps more than we ever have before. But suggestions that all this this extra hygiene could weaken our immune systems are unfounded.

Research shows that children can become infected with the coronavirus and spread it to others. Though rare, some kids do become severely ill and a few have died from COVID-19.
It’s hard to discuss COVID without referring to white blood cells. Here is a primer on the two you need to know about.
Nanoparticles dressed up in cell membranes snag SARS-CoV-2 virus particles before they reach human cells.
The cutting-edge tools could greatly expand our understanding of different species’ immune systems, and also help humans prepare for future disease outbreaks.
There is speculation about whether a population can achieve some sort of immunity to the virus with as little as 20% infected.
If you have had COVID-19 already, are you protected from another bout of the illness? And is the presence of antibodies in your blood a guarantee of immunity?
Just focusing on spike proteins might not offer the complete immunity.
OM85 harnesses molecules extracted from bacteria, and has shown promise in preventing severe respiratory infections. It seems to work by training the immune system.
Why does COVID-19 hit men harder than women? Is the disparity in mortality rates due to male hormones or an underlying difference in the male versus female immune system?
Racism – and the chronic stress it causes – leads to poor health among African Americans. It may change the way genes are expressed, leading to increased levels of dangerous stress hormones.
An antigen test was given emergency use authorization by the FDA in early May. A biochemist explains how COVID-19 antigen tests work.
Between 10-15% of all cells within the brain are microglia.
‘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.
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.
Vaccine development is usually a long process. The coronavirus pandemic is forcing researchers to innovate and test potential vaccines faster than ever before.
