Usually you only need a single vaccination each flu season since the seasonal flu vaccination contains vaccine against the three mostly likely types of flu to be circulating during that season. In the pandemic of H1N1 in 2009, two vaccinations were needed, one for the three types of seasonal flu and one for H1N1/09 "Swine Flu." In the 2010-2011 flu season, the H1N1 vaccine is included with two other flu virus vaccines to make up the seasonal flu vaccination. If you had the swine flu vaccine in 2009, it won't hurt to have it again in the seasonal flu vaccination.
If another new flu virus is found to have developed, then, like in the 2009 pandemic, vaccines for the new flu virus may be produced in time to be taken, but not in time to be included in the seasonal flu shot as one of the three virus vaccines. Then, a second vaccination for the new flu may be required as it was in the 2009 - 2010 flu season of the pandemic.
Other than the potential sore arm, it won't hurt to have flu vaccines more than once for most people. Ask a doctor, pharmacist, or the clinician delivering the vaccination for advice before the vaccine is given.

What vaccine hurts more influenza or measles?
The MMR vaccine stings more than the flu shot.
Is the Swine flu vaccine more dangerous than swine flu itself?
no, it is not, remeber, the vaccine is a dead or weakened version, of H1N1I was just given the shot and have had no reaction to this point.
Do you have to wait a full year between flu immunizations?
yes, if it is for the same vaccine, but not if it is for a new vaccine against a different flu
Why does the flu vaccine developed each year not always work?
The flu vaccine is not a new vaccine that is developed from scratch every year. The flu virus mutates rapidly into different strains, meaning that a vaccination from a previous year will not protect you for another year's strain. The vaccine is modified to take account of this - it is not developed from scratch every time.
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.
How long to wait between flu vaccine and shingles vaccine?
interval- flu vaccine and the shingles vaccine
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.
What is the meaning of flu shot clinics?
A flu shot clinic is a place where you can go to receive the flu vaccine. During flu season these clinics are set up so that more people can be seen to receive the vaccine.
Can flu vaccine be given at the same time as the varicella vaccine?
Yes, you can get flu vaccine and varicella vaccine at the same time.
Why Every year a new influenza vaccine is developed What is the most likely reason that doctors do not use the same vaccine each year?
Typically the flu vaccine is trying to predict the possible states of the flu coming for that season. The flu virus mutates so rapidly that they are always trying to predict what's coming next. That's why you can also still get the flu even if you get a flu shot. STUDY ISLAND ANSWER:The virus which causes influenza adapts each year to the last vaccine in order to survive and reproduce.
Will the swine flu vaccine hurt a ten year old?
If you mean will the injection of a flu shot/jab hurt, then no more than any injection, but it might hurt a little just for a short time during the injection. If you mean will the vaccine be dangerous for a ten year old, it has been proven to be one of the safest vaccines even for infants and the elderly over decades of use.
What does the H1N1 vaccine cover?
Originally in 2009 the vaccine for the pandemic swine flu was a monovalent vaccine, which means it was made to only prevent that one type of flu. Then for the 2010-2011 flu season, a trivalent vaccine was made for the regular flu just like every year. Trivalent means it is made to cover/prevent three different kinds of influenza virus infections. For the most recent flu season in the Northern Hemisphere, the "regular" flu shot contained the vaccine for swine flu and two others. So, the monovalent H1N1 vaccine covered only one type of flu: the pandemic swine flu. But the trivalent seasonal flu vaccines cover three types of flu (one of which, for the 2010 - 2011 flu season, is Swine flu H1N1/09).
