I am not a doctor but I am 90% of the way to a degree in natural health (naturopathy). Immunity to a specific bug is never better than a healthy immune system that will respond to anything. The flu shot is always a guesstimate concoction of what bugs someone thinks will be prevalent the next year. Maybe they get it right, maybe not. Sometimes the reaction is not to the deactivated bug, but the other junk in the preparation.
Naturopathy would say a healthy immune system depends upon the basics-- good food (esp protein); antioxidants (Vit A, C, E, selenium) to assist in their activation and prevent destruction by free radicals; sufficient rest a receptive, happy attitude towards life (stress is a big depressor);healthy gut flora (active yogurt culture or acidophilus pills);and most of all as little sugar in the diet as possible (that includes fruit and juice). Sugar depresses immune funcion. The classic study is that a glass of orange juice depresses the immune system 50% for 5 hours.
There is a great homeoathic preparation called oscillococcinum (Oscillo for short) that if taken at the first sign of "fluey" symptoms often stops the condition in its tracks. People can also take shark oil which kicks the immune system into gear. I have not had the flu in at least 15 years since I started on this kick.
