TED-Ed: Could one vaccine protect against everything? | TED-Ed

The video explores the concept of a universal vaccine, focusing on the flu virus and its hemagglutinin proteins. It explains how the immune system recognizes and responds to these proteins, and the challenges posed by antigenic drift and shift. The video discusses the potential of targeting conserved regions of the virus for vaccine development and highlights promising research involving ferritin nanoparticles and T cell responses. It concludes with a look at the future possibilities of universal vaccines and the challenges that remain.

What are conserved regions of hemagglutinin and why are they important for vaccine development?

How does the engineered ferritin nanoparticle contribute to vaccine development?

What challenges exist in creating a truly universal vaccine against all infectious diseases?
