The risk of negative effects of both mRNA COVID vaccines is very low, but older adults fare better with the Moderna vaccine, researchers find.

Targeting the bubble-like membrane of a virus, rather than its proteins, could lead to a new generation of antivirals.

Newly-discovered, exceptionally potent antibodies can neutralize virtually all known variants of the COVID-19 virus—including Omicron.

Growing resistance to antibiotics is renewing interest in phage therapy for conditions like urinary tract infections.

Researchers have solved the mystery of how the hepatitis C virus evades the immune system and spreads through the body: it puts on a "mask."

New findings shed light on how the highly infectious Lengya virus, which has recently transferred from animals to people, is able to enter human cells.

A bat protein called ASC2 has a powerful ability to inhibit inflammasomes in mice, thereby limiting inflammation.

"We need a better vaccine, one that provides years of robust protection with fewer booster shots against a variety of SARS-CoV-2 strains."

Researchers dig into what they've learned after a year of studying long COVID—as well as what they don't know about the condition.

"...frequent COVID surveillance testing protected nursing home residents and undoubtedly saved lives," says Brian McGarry.
