Immunology

Other diseases with long-term symptoms can help us understand how COVID can affect us long after the virus itself is gone.

Glycans, the complex sugars that stud cellular surfaces, are like a language that life uses to mediate vital interactions. Researchers are learning how to read their meaning.

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.
