There's a vaccine being developed now that would protect you against every strain of the flu— even ones that don't exist yet. But influenza is constantly mutating, so is a universal vaccine even possible? And how do you design a vaccine that will be effective against future strains? Explore how scientists are developing new ways to help our immune systems fight viruses. [Directed by Igor Coric, Artrake Studio, narrated by George Zaidan, music by Nikola Radivojevic]. 

 TED-Ed: Could one vaccine protect against everything?

Could one vaccine protect against everything?

Unlocking the secret to a universal flu vaccine hinges on targeting the virus' conserved regions, elusive yet pivotal for broad immunity.

A leap in vaccine technology using ferritin nanoparticles shows promise, successfully protecting mice from lethal flu strains in tests.

Envisioning a universal vaccine against all diseases remains a dream, challenged by our immune system's complexity and adaptability.
