Every year, about six million Dutch people receive an invitation for the flu shot from their GP. These are children and adults who run an extra risk of becoming seriously ill from the flu. These are people aged 60 and older, but also people with, for example, lung or heart disease. The flu shot is free and not mandatory.
The flu shot is a vaccine that consists of different types of dead flu viruses. After receiving the flu shot, the body produces antibodies against the viruses in the flu shot. Two weeks later, the body has produced enough antibodies to protect the body against the virus. Its composition differs every year.
