Why typhoid vaccine may also protect against other infections

About this video

New research by the University of Liverpool and Liverpool School of Tropical Medicine shows that vaccination with weakened strains of Salmonella may also protect against other infections.

The researchers hope that the findings could impact vaccination strategy in the developing world, where infectious diseases are common and where broader protection could potentially save many lives.

Professor Melita Gordon explains the background and findings of the study, which is published in the journal Scientific Advances.
