Universal flu vaccine success
Trial Results
The vaccine showed 95% efficacy against all tested influenza strains in a 30,000-participant trial. Protection lasted at least three years, eliminating the need for annual vaccination.
Broad Protection
Unlike current vaccines targeting variable surface proteins, the universal vaccine targets conserved regions that are common to all influenza viruses, including potential pandemic strains.
Public Health Impact
Flu kills 290,000-650,000 people annually worldwide. A universal vaccine could save hundreds of thousands of lives each year and prevent future pandemics.
