When it is made available! It takes you 2 wks to make enough antibodies to be protective. I find no value in the myth that protection fades in weeks or months. If it has the strains in it that you are exposed to it will be protective for the full season & maybe longer. Some flu strains don't make it into the vaccine so all are never protected from all strains.

It is not clear whether immunity wanes after a period of months after vaccine, but most people recommend flu vaccine in September or October. They also recommend that an unvaccinated person can still benefit from getting the vaccine as late as January (not the best though)
