Seasonal influenza vaccination strategies
The immunity that is elicited by influenza vaccines is not as long lived as the immunity following natural influenza infection. This is especially so for individuals in the so-called risk groups, hence people have to be vaccinated annually. There are three influenza immunisation strategies used in Europe: to protect the vulnerable, to protect healthy children, adolescents and adults and to reduce overall influenza transmission.
