The flu shots are to prevent the flu, not to treat the flu.

It will not be necessary to get a flu shot after you have had the flu, if you know what type of flu you had for sure (by lab testing). If you are not sure that it was the seasonal flu or another type of flu (like Swine Flu), then taking a vaccination will be a good idea to be sure you are protected for the other strains of flu. It will not hurt to take a flu shot for the same type of flu you had, and if the vaccine is for a different type, then you will have that added protection. You should usually wait until after the symptoms of active fever are gone before getting a flu shot, though.

Flu shots work by exposing you to a small amount of weakened or dead viruses that cause a specific flu, or sometimes the vaccine will cover several (the seasonal flu vaccine usually contains three strains), so that your body can build immunity to them before being exposed to the full strength viruses in the environment.

For the 2009 - 2010 flu season in the US, you are encouraged to get two vaccinations for the flu. One for the seasonal flu (it protects against three flu strains) and one for the A-H1N1/09 swine flu. If you have not had lab confirmation of the type of flu you already have had, then the CDC still recommends you get both vaccines.

If you get a swine flu shot will the swine flu disappear in a week?

The swine flu shot is used to prevent the flu, not to treat the flu if you already have it. To treat the flu, antiviral medications are more likely to be prescribed, such as Tamiflu.


How do you get the flu when you already got a flu shot?

There are many different types of flu and the seasonal flu shot only prevents three of the most likely to be circulating flu viruses. So if you happened to get exposed to a type of flu that wasn't in the vaccination, then you could get sick from it.Another reason might be that you caught the flu before you got the flu shot and so there was not time for the shot to work before you got sick.Another reason might be that you got the shot and then were exposed to the flu before your immune system could give you immunity from the vaccination. It takes around two weeks after getting the vaccination for an adult to have full immunity from it. For children under 10, a series of two vaccinations are needed given approximately a month apart, then it takes another few weeks before the body has developed the full immunity, so exposure during any of those time frames before full immunity can cause illness in those children.

Can you throw up from the flu shot?

I suppose it is possible since each individual reacts to medications differently and experiences different side effects....but it is very unlikely that is why you threw up. Especially if you have no other symptoms. If you already caught the flu before getting the shot, then it is possible that you threw up because of the flu, but it is a less common symptom of the flu.


Is the Swine Flu shot really a shot?

They don't shoot you, and it isn't a 'shot' of a drink, it's a needle in the arm. In the 2009-2010 flu season there was a mist as well as a shot for the vaccination for swine flu. In the 2010-2011 flu season the vaccine for swine flu protection is included in the one vaccination for the seasonal flu.


Is it safe to get both the seasonal flu shot and the H1N1-09 virus flu shot?

Should people that work in a daycare get flu shot?

yes, so you dont get what the kids have or give it to them.


If you have had H1N1 do you still need to get the shot?

If the correct test was done to confirm the H1N1, then, no there is no need to take it again. But if you are not absolutely sure that the test confirmed the A-H1N1/09 flu, then it will do no harm to take the vaccine. The only test that can be relied upon to be an absolute indicator of the vaccination is the RT-PCR test, and not the rapid tests done in the doctor's offices. you should have some immunity against 2009 H1N1 flu and can choose not to get the 2009 H1N1 vaccine.
