Immunology

A newfound hub of immune system activity at the back of the brain solves a century-old puzzle.

Researchers are tracking the different strains of SARS-CoV-2 and studying how they spread through our population and our bodies.

While the study of the SARS-CoV-2 virus was the most urgent priority, biologists also learned more about how brains process information, how to define individuality and why sleep deprivation kills.

A novel form of immunological memory that was mostly ignored for a century extends the benefits of vaccines. It could be of help in ending the COVID-19 pandemic.

Studies suggest that self-disseminating vaccines could prevent the "spillover" of animal viruses into humans as pandemic diseases.

Researchers are examining the power of subtle genetic weaknesses in the immune system to affect the severity of infectious diseases, including COVID-19.

Herd immunity differs from place to place, and many factors influence how it’s calculated.

Many theories have been offered for why the official COVID-19 toll on the Indian subcontinent has been surprisingly low. The best explanation may be the shortage of good, timely data.

Neuroscientists could use brain waves to spur immune cells into action against the disease — but the process is almost too fantastic to believe.
