Can you get the flu from the vacine?

No, you cannot get the flu from the swine flu vaccine. What the H1N1 vaccine does is inject dead or weakened flu germs. That way if you do get the flu, your body will know what to do. But you can't get the flu from the vaccine.


Are you protected if expired flu vaccine was used?

Probably not. Each year the ingredients in the flu vaccine are different, because each year different strains of the influenza virus are going around. They have to make up a new vaccine each year, to be sure it contains all the right strains that will provide immunity for the kinds of flu that are circulating at that time. Since the vaccine for the seasonal flu for this year in the Northern Hemisphere has just been manufactured and released very recently, it would not seem possible for it to be already expired. If you use a vaccine from a prior year (the more likely scenario if the expiration date on the bottle has already passed), then you will not be fully protected against the strains of virus that will be causing flu this year and may be taking something that could be harmful in addition to providing no protection. You should talk to those at the source of the vaccine to find out why the vaccine would be expired.

Are you immune to Influenza after you have had it?

You are not immune to Influenza. Even getting the yearly flu vaccine is no guarantee that a person won't get the flu. You can get the flu but it won't be as bad as it could be if you hadn't received the flu vaccine.

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.
