A vaccine usually trains your immune system to recognize one target. Here, the target is basically “anything that doesn’t belong in the lungs.

Scientists found an unexpected viral hitchhiker lurking inside a common gut bacterium – and it was twice as prevalent in people with colorectal cancer.

Biochemists at Caltech have identified how viruses have converged on a method for killing bacteria. The researchers have homed in on an underexplored small transporter called MurJ that is a vital part ...

Stanford researchers develop breakthrough nasal spray vaccine that could potentially protect against a variety of infections, ...

Researchers have invented a new vaccine that protects mice from respiratory viruses, bacteria and allergens – the closest yet ...

Researchers suggest a vaccine could replace multiple jabs every year for seasonal respiratory infections and be on hand in the event of a new pandemic.

Antibiotic resistance is rising fast, killing tens of thousands each year in the U.S. alone—and scientists are racing to find ...

Drug-resistant bacteria are becoming harder to treat, pushing scientists to look for new antibiotic targets. Researchers have now discovered that several unrelated viruses disable a key bacterial ...

In an early animal test, a new nasal-spray vaccine has shown promise against a variety of germs and a common allergen, ...

For much of modern biology, scientists argued that viruses are not alive, pointing to a basic limitation: they cannot make proteins on their own and must depend entirely on the cells they infect for ...
