One H1N1/09 "Swine Flu" vaccination was determined to be enough in the 2009 clinical trials of the brand new vaccine for the brand new virus. If you had the vaccination it will provide immunity for life to that particular virus. If the virus mutates into a strain that is much different from the one in the prior vaccine, then there may be a need for a new vaccine for the newly formed virus. So far, that has not happened.
You need a seasonal flu shot annually because of the problem with the easy mutations of flu viruses. In the 2010-2011 flu season, the vaccine for the swine flu is included with the other vaccines in the seasonal flu vaccinations, so if you did not get the separate shot last year, this year you will get lifetime immunity from that exact type of flu in the "regular" flu vaccination. (It won't hurt and might help to get that vaccine again).
There is no similarity between penicillin and the flu vaccine. See the related questions below for more information on who should not get vaccinated for the swine flu.
Anyone who has not had a flu vaccination each year since the pandemic and/or has not already had illness from the exact strain of flu as the pandemic swine flu. The annual flu vaccine has contained the H1N1/09 swine flu since the first regular flu season (in 2010 - 2011) after the discovery of the new strain in 2009. In the 2009 - 2010 flu season, a second vaccination against swine flu was required to be taken, in addition to the regular seasonal flu vaccination, to be immune. See the related question below for a list of those mostly likely to get, and have complications from, the 2009 swine flu (if they have not been vaccinated).
No
Do you mean vaccination? The swine flu doesn't take vacation.
You would not use an antibiotic to stop yourself from getting a disease, you use a vaccination, and yes, there is a vaccination for swine flu.
Anyone who is not vaccinated against it. Those at highest risk of contracting it or having complications with it are listed in the related question below.
The swine flu H1N1/09 virus survives as do all viruses, by invading a host to support it and do its work to reproduce. Viruses can not live without a host to infect. That is why some viral diseases have been eliminated by vaccination programs, if everyone is vaccinated, no one becomes a host. Don't let flu viruses survive inside you, get a flu vaccination every year prior to flu season.
Yes, it's a vaccination that helps you prevent the swine flu infection.
I will say that you potentially can. My boyfriend was vaccinated as a child, and he contracted the virus within a few weeks. We don't know if perhaps the polio was already in his system and he was just vaccinated too late, or if something went wrong with the vaccine and he got sick as a result.
Most people who are not vaccinated against the swine flu or who have not had the swine flu will get it if exposed to it. Those who have had the vaccines will be immune.
If you actually had laboratory confirmation that you had the A-H1N1/09 influenza, then you would be as or better protected from that same virus from then on for life. The vaccination is proven in clinical trials to be approximately 90% effective in adults with healthy immune systems. One of the reasons the vaccines are is not 100% effective is that the strain of the virus that is chosen to be the one in the vaccine may not be as good a match for the exact strain you catch in the wild, since there can be slight mutations.However, the vaccination is proven safe and effective as any seasonal flu vaccines are, so if you are not sure 100% by laboratory testing that this is the flu you had, you should go ahead and get a vaccination. If you did have the same flu, there is no problem with having the vaccination too.
If you have chronic heart disease then you have a greater risk of becoming more seriously ill from swine flu than the general population.So if you have chronic heart condition then i would suggest you to take swine flu vaccination and steps are well described in the linkhttp://www.tictacdo.com/ttd/Get-a-Flu-Shot
