There are different kinds of H1N1 viruses, you can catch the exact same kind only once in your lifetime. The Type A, H1N1/09 influenza virus that caused the pandemic is different than other H1N1 viruses. So you could get infected by more than one type of H1N1 in your lifetime, but not the exact same Type A, H1N1/09.
Usually your body recognizes a very similar type of flu as the same and can prepare defenses for it quickly because of the prior immune response to the other one, but if different enough you will have to start over with a new immune response that allows time for the virus to make you feel ill before you can begin to "kill" the new type.
The answer is that you can catch the same one only once, but you can still catch all the other H1N1 viruses (one time each) after that.
A person with Sarcoidosis not get a seasonal flu shot
Actually, it is more likely to catch the H1N1 in America than in Mexico. You should take that shot even if you are not traveling to Mexico soon.
nooooooooooooooooo! please don't
no.
Yes. There is no longer a waiting period between when you get any influenza shot, including H1N1, and when you can give blood.
adjuvent
Yes. In fact, now the seasonal flu shots are combined with the H1N1 Virus flu shot, so you don't have to get two.
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.
Yes. You can also get a nasal version where you have to sniff it. Personally, the shot didn't hurt.
The shot has been tested just as all flu vaccines are and it perfectly safe.
