Emergency vaccination programmes – rolled out in response to outbreaks of five major diseases – are believed to have reduced deaths by around 60% over a period of 23 years, according to a new study, BBC reports.

They studied 210 different incidents from 2000 to 2023, covering 49 different countries. Read the full story here.
