Yes: The antibodies generated by seasonal flu vaccine will last for years against the strains in the vaccine.People get confused about protection, because in a given season, the vaccine can only cover 3-4 strains, while there may be a new strain emerg that is not in the vaccine.Waiting until late in the fall only increases your risk you will be unprotected against an early exposure.
