Current vaccines target regions of the virus that are highly variable. These vaccines need to be updated regularly and administered each year. Vaccines in development target conserved regions to avoid the need for regular updates.


However, these vaccine concepts produce a poor protective immune response that is also difficult to maintain. Our vaccine overcomes such issues by targeting regions of the virus, which are highly protective and easy to induce an immune response against as well as limited in variability, thereby inducing protection which can be easily maintained.
