Scientists have found a "blueprint" for a universal flu vaccine, according to the leader of a research project into influenza, said Professor Lalvan:
Our findings suggest that by making the body produce more of this specific type of CD8 T cell, you can protect people against symptomatic illness. This provides the blueprint for developing a universal flu vaccine.
We already know how to stimulate the immune system to make CD8 T cells by vaccination.
Now that we know these T cells may protect, we can design a vaccine to prevent people getting symptoms and transmitting infection to others.
This could curb seasonal flu annually and protect people against future pandemics.
