According to a recent issue of Vaccine (1), a team of UK based researchers have genetically modified the Hepatitis B virus shell to contain inserts from influenza virus. The resulting "virus-like particle" is not a live virus, but a completely safe and inert product which can be used as a new universal vaccine against influenza infection.

Unreliable yearly flu jabs could be a thing of the past as researchers close in on technology that will take down the deadly virus once and for all.
