Last year's vaccine may not be effective for this year's virus. A new vaccination each year is needed to prevent illness from the three flu viruses most likely to be circulating during the upcoming flu season. These may or may not be viruses to which you have been previously exposed or vaccinated. The vaccinations are needed annually not only because the three viruses epidemiologists are expecting can be different each year (and some may be completely new mutated viruses never seen before), but also because there can be some loss of the effectiveness of the vaccines in some people over time, and the annual vaccination makes sure you are still protected with full immunity for the viruses expected that year.

Has anyone who did not get the flu shot died from the flu?
Yes, each year in the US approximately 36,000 people die from the flu; most did not have a flu vaccination.
Why do doctors recommend that people get a flu shot each new flu season?
Because each season the flu shot contains a new range of flu virus strains to protect against that year's likely flu types. The types are continuously changing because a virus such as the influenza mutates quickly, making it difficult for the immune system to recognize and destroy the new strains, and necessitating a new vaccine.
Should you get a Swine Flu vaccination if you got a seasonal flu shot?
Last flu season, 2009-2010, you needed two shots. But this year the seasonal flu shot also protects against swine flu, so, in the US, you only need one flu shot for the 2010-2011 flu season.
Should you get a flu shot with a sinus infection?
You have to wait until your better then you get the flu shot
What if you have been exposed and did not have a flu shot?
You may get the flu. Next year get the flu vaccination.
Should I get the flu shot after getting over the flu?
yes
Should a person with sarcoidosis get the H1N1 and flu shot?
A person with Sarcoidosis not get a seasonal flu shot
Is there any harm in receiving two full dose flu vaccines in one year?
No, but if you get swine flu and regular flu shot, it will be harder to get the flu.
You are taking amox-clav can you still get the flu shot?
Yes, you can still get the flu shot. The flu shot should not be gotten if you are currently ill, but if you are on antibiotics, it is OK to get.
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.
Would it be worth getting flu shot although you have had the flu?
Yes, because the flu changes from year to year and if you don't know if the flu you had was this years or last, why take the risk. Get one every year.
How long must a person be free of cold and flu symptoms before getting a flu shot?
While a flu shot will not be effective against any active flu symptoms it will protect against the other flu strains contain in the shot. Flu symptoms such as high fevers, upper respiratory problems should be controlled but the flu virus in a shot is a 'dead' non-active virus and should not affect or cause any current virus.
