Is the Swine Flu vaccine effective against the regular flu?

Each flu vaccine is targeted to specific varieties of the flu virus. Unless another type of flu is very similar to the targeted virus, it will not be prevented with that vaccine. Having said that, since the 2010-2011 flu season through to the current 2011-2012 season, the "regular" seasonal flu vaccine, which always contains three types of flu vaccine (trivalent), has included the swine flu along with the other two varieties to which the vaccine was targeted. So in that sense, at least currently, the swine flu vaccination is effective against the regular flu since vaccines for each type are put together in one vaccination.

Why isn't there a one time vaccination for the flu shot?

The flu virus mutates enough each year that immunity to last year's strain doesn't mean you will be immune to this year's strain.That's why, each year, they manufacture flu vaccine based on what they think that year's strain will look like. Sometimes they're wrong, and that year's vaccine isn't effective against that year's flu, but this is fairly uncommon.The H1N1 vaccine is tailored specifically to the swine flu outbreak this year, and has been proven to be effective against it.

Vaccines against the flu are different every year why is this?

This process helps ensure that the vaccine is effective against the specific flu viruses circulating each year.
