There is a lot of potential in creating a flu vaccine that would make all receivers of the vaccine immune to all currently known strains and all potential future strains of the flu, including permanently or semi-permanently.
This vaccine could work either by blocking the receptor sites that strains of the flu generally attack or making a generalized flu strain that allows the human body to mutate the strain into any possible strain of the flu, and thus develop a resistance to any of those strains, including over time, as the strains of the flu enter the body.
The universal flu vaccine could involve the usage of some type of bio-engineered disease prevention technology, or in other words, some type of bio-engineered technology to prevent diseases.
