New research co-led by Burnet Institute and WEHI has uncovered how the human immune system fights Plasmodium vivax, paving ...

Viral infections remain a significant global health challenge, as exemplified by recent pandemics. The complexity of virus-host interplay poses major ...

Bacteria can play established roles both as pathogens during infection but also as part of the host microbiota. The immune response to bacterial infection is a critical defence strategy protecting the ...

The immune system’s first encounter with a virus or vaccine establishes a “starting template” that shapes its response to new variants, a phenomenon often called immune imprinting. A new study shows ...

Your immune system may be weak if you have frequent, severe, or extended infections. Learn more signs of a weak immune system.

When food is scarce, stress hormones direct the immune system to operate in "low power" mode to preserve immune function while conserving energy, according to researchers at Weill Cornell Medicine.

Scientists have discovered a new process in our immune systems that leads to the production of an important family of anti-viral proteins called interferons. They hope the discovery will now lead to ...

Herd immunity occurs when enough people in a group are immune to a specific infection that it cannot spread easily from person to person. Vaccination programs have been successful in creating herd ...

Researchers at the University of Queensland (UQ) have identified how a common bacterium is able to manipulate the human immune system during respiratory infections and cause persistent illness. The ...

Northwestern Medicine scientists have identified the cellular mechanisms that cause immune cells to differentiate and ultimately lose function during viral infection, findings that could improve ...

A first-of-its-kind study led by the University of Oxford has successfully investigated human immunity against COVID-19 in people who already have antibodies against it. The results suggest that ...
