Well, anyone who has regular visits to a doctor at all, or has prescriptions filled regularly at a pharmacies, will probably pestered about getting flu shots yearly, at least. If you are young and healthy, I don't think they are pestering you for your sake, but to build immunity and prevent its spread. Healthy people should really look at flu shots as a kind of duty to their fellow citizens, who may be more vulnerable.
