What Does a Flu Shot Do?
The flu shot is a vaccine that consists of different types of dead flu viruses. After receiving the flu shot, the body makes antibodies against the viruses in the flu shot. Two weeks later, the body has produced enough antibodies to protect against the virus. Its composition differs every year.
The invitation for the injection goes to about six million Dutch people: 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 given by general practitioners, is free and not compulsory.
