H1N1 is the general name of several influenza viruses, of which H1N1/09, the pandemic Swine Flu, is one. It is a Type A influenza virus and the H and N stand for the two proteins on the outer surface of the virus. See the related question below with more information about the make up of H1N1.

∙ 12y agoFirst seed stock of the virus the vaccine is to be made to combat must be selected, collected and grown so that there will be parts of it to put in the vaccine. The World Health Organization and Centers for Disease Control and Prevention along with scientists and epidemiologists examined the viruses that were isolated from patients and selected specific strains of it and tested to see how well they that could be "grown" or cultured. This needed to be easily and quickly done. Once the stock of the virus that matched well to the types spreading in the pandemic was selected, it was distributed to drug vaccine manufacturers to begin the development and production.
The drug companies used chicken eggs as a culture medium and "grew" the virus. Then they harvested portions to use in the vaccines and purified them to remove as much egg protein and potential contaminants as possible. The viruses were then either severely weakened with heat or chemicals (or other methods) so they would be unable to cause infections anymore (for live attenuated/weakened vaccines), or they would be completely "killed" to use in the inactivated vaccines.
In the US adjuvants which help increase the production of the vaccines are not being used with this vaccine.
The viruses are then combined with the other ingredients that may or may not include preservatives, along with stabilizers (Gelatin sometimes), and liquid such as saline to be the medium to contain the vaccine. See the ingredients list in the related questions below for a complete list.
The vaccine is made by growing samples of flu virus inside fertilized chicken eggs, then breaking out the key proteins that provoke an immune response. Then they are purified, tested and packaged into syringes or vials for distribution around the country.
swine flu vaccine are produced mainly by two methods one with the help of fertilized chicken eggs and other with cell cultured based method. Research is underway to confirm which method is best in terms of protection and yield . by Syed baker

Does the H1N1-09 vaccine contain the substances that may cause cancer?
No, the H1N1 virus does not contain carcinogens.
When was the H1N1 shot made?
There have been several versions of H1N1 influenza over the years. But the most recent H1N1 flu was the pandemic "Swine Flu" A-H1N1/09. The monovalent (made with and for protection against a single virus) vaccine for it was made just before the flu season in fall/winter 2009-2010. Again, in the 2010-2011 flu season the same vaccine was included in the trivalent (made with three viruses) vaccine for the seasonal flu. If you had the monovalent vaccine in 2009, then you should still take the trivalent vaccine for the 2010 flu season. It will not hurt to get another dose of the H1N1/09 virus vaccine, it might enhance the immunity of some people, and you need to be vaccinated for the other two viruses that are most likely to be going around in this season.
Is another term for H1N1 Swine Flu vaccine Pneumococcal vaccine?
No, the "pneumonia vaccine" is to protect against several types of pneumonia that are common and will not protect against the A-H1N1/09 virus. See related questions below.
Are there toxins in the H1N1-09 swine flu vaccine?
No, see below for the list of ingredients. It has been proven to be a safe and effective product to use to avoid the A-H1N1/09 flu and its symptoms and complications.
Can the H1N1 vaccine make one sicker if already infected with the H1N1 virus?
No, the H1N1 vaccine won't make you sicker or healthier if you already have H1N1.
Can you develop Multiple schlerosis from having the H1N1 vaccine?
the h1n1 vaccine does not work all the time
Does the US 2012-2013 flu vaccine contain swine flu vaccine?
This year's vaccine does contain Type A, H1N1/09 vaccine made from the specific type (i.e., mutation) of the H1N1/09 virus that is expected to circulate in the US in flu season this year. That specific strain is called: A/California/7/2009 (H1N1)pdm09-like virus The vaccines made from the other two selected influenza strains that are in the 2012-2013 flu vaccines in the US contain: A/Victoria/361/2011 (H3N2)-like virus B/Wisconsin/1/2010-like virus (from the B/Yamagata lineage of viruses)
When will there be an H1N1 vaccine?
For H1N1/09, Novel Swine Flu: they began developing the vaccine in the US as soon as the virus was isolated and the epidemics were spreading in April and May 2009. The vaccines were approved by the Food and Drug Administration (FDA) on September 15, 2009. Other H1N1 vaccines: these have been developed in the past. One that is well known is the 1976 vaccine that was associated with an increase in Guillain-Barre Syndrome after the administration of the vaccine. It was made an entirely different way than these flu vaccines are made today. There are also some H1N1 vaccines developed for use by pig farmers for the prevention of the type of H1N1 that is a disease of pigs that people only rarely get when they are in regular close contact with the pigs.
Has anyone died from H1N1 vaccine?
I did...:(
Who invented the H1N1 flu vaccine?
The pandemic H1N1/09 virus was not discovered by one doctor, but was isolated and studied by a team of CDC scientists and WHO scientists along with the Mexican health authorities as a joint effort.
Can one take the H1N1 vaccine while infected with the H1N1 virus?
You can take the vaccine but it will not stop the disease. Vaccinations prevent disease but they do not cure them.
If you had H2N2 flu in 1957 do you need H1N1 shot?
Yes. There has never been a vaccine made for a strain that was close enough to the current H1N1/09 pandemic flu to have allowed our immune systems to make antibodies that would be a good fit to the new flu. So, no prior vaccinations will have provided any protection for the pandemic swine flu. When you can get an H1N1/09 flu vaccination, you should go ahead and get one to be protected.
