New research on gonorrhea "suggests a way to halt the growth of this sexually transmitted infection in the host's body."

A new, experimental vaccine for respiratory syncytial virus (RSV) shows early promise in a Phase 1 clinical trial.

Evidence is starting to emerge that one dose of the HPV vaccine may eventually prove to be sufficient for protection, report researchers.

Now that it's standard to vaccinate babies for the stomach bug rotavirus, researchers are observing an unexpected trend: fewer cases of type 1 diabetes.

New research addresses a hurdle in the way of an RSV vaccine.

A new discovery could lead to safer and more effective maternal vaccines, which protect pregnant women and their newborns from dangerous infections.

Training certain cells "might be one way we can make a more effective vaccine for TB."

"...stalk antibodies may be able to provide protection against influenza and could enable scientists to design a broader, more effective influenza vaccine."

The discovery of a broadly protective, naturally occurring human antibody could lead to better ways to prevent and treat the flu.

Scientists may be able to take advantage of different segments in the intestine to develop new treatments for gut disorders or better oral vaccines.
