A new study reveals that emergency vaccination programs, implemented in response to outbreaks of five major infectious diseases (Ebola, measles, cholera, yellow fever, and meningitis) between 2000 and 2023, reduced deaths and infections by approximately 60%. The comprehensive study, covering 210 incidents in 49 countries, also highlights significant economic benefits, estimated at $32 billion, from averting deaths and disability, though researchers believe this is a significant underestimate of overall savings.
