All Type A influenza viruses have H and N (these are two proteins that are on the outer shell of the virus particle--Hemagglutinin and Neuraminidase). The other influenza virus types B and C each only have one serotype and they do not include the H and N.

What is the full form of H1N1 virus?
The H and N stand for the two proteins on the capsid (coat) of the virion that causes this influenza. The H stands for Hemagglutinin, and the N stands for Nueraminidase. The numbers in the names of flu viruses refer to the configuration of these proteins. See the related questions below for more details.
Why is flu called flu?
The scientific names for the virus strains that cause the flu are derived from the proteins on the virus capsid (coat), and usually some indication of the location from which the virus strain was first obtained or a type of known virus to which the new strain is similar, e.g., "Perth-like".In the naming convention of viruses, the protein classifications become part of the name as in H1N1; H for the haemagglutinin and N for the neuraminidase. There are different subtypes of viruses using the H and N nomenclature, for example the H5N1 subtype is the Avian (Bird) Flu and H1N1 subtype is the Swine flu.The common names usually are based upon where the virus was first discovered, e.g., The Hong Kong Flu, Fujian Flu, etc. or in what animal the virus is endemic, e.g., Swine Flu, Bird Flu, Horse Flu, etc.See the related question for more information on the naming of flu viruses.

What are the meanings of A - H - N - 1 - 09 in the A H1N1 09 flu name?
Background information about names of flu virus strains:For background, H1N1 is the name used to identify several subtypes of flu viruses. A few of the influenza viruses that are in the group of Type A Influenza viruses are labeled that way or in similar ways.These influenza A virus strains are categorized according to two proteins found on the surface of the virus: hemagglutinin (H) and neuraminidase (N). All influenza A viruses contain hemagglutinin and neuraminidase, but the structure of these proteins differ from strain to strain due to rapid genetic mutation in the viral genome.Influenza A virus strains are assigned an H number and an N number based on which forms of these two proteins the strain contains. There are 16 H and 9 N subtypes known in birds, but only H 1, 2 and 3, and N 1 and 2 are commonly found in humans. There are also Influenza type B viruses.Example Swine Flu:An example is the new "Swine Flu" virus circulating in 2009, the "Influenza A, Novel H1N1/09" Virus. It evolved from a virus that started as a flu that only pigs could get, which is called H1N1, too. But that mutated to a strain that could also infrequently infect humans who were in very close contact with pigs, such as farmers who raised them. The new "Novel H1N1" virus was a further mutation that combined human, bird, and swine flu genes.The Centers for Disease Control and Prevention and World Health Organization call the pandemic 2009 "Swine Flu": Influenza A, Novel H1N1 Virus. You may also see it written as the "Novel H1N1 Influenza virus", or "Novel Influenza A, H1N1 virus", or "H1N1, formerly Swine Flu".It has different names in other countries as well, for example: it is called Schweinegrippe in Germany, la Grippe A in France, Mexican Flu in the Netherlands, SOIV (Swine Origin Influenza Virus) in Canada, and la epidemia in Mexico.The reason they call it "Novel" is that it is new. It is a strain not seen before. There are other strains of H1N1 influenza, but this one has different and new genetic material than the previously seen strains of Type A flu.What A-H1N1 means:"A" stands for the influenza sub-type or strain.These Type A viruses have a protein coating that surrounds them, called a capsid. The surface proteins making up the capsid in these virus strains are Hemagglutinin and Neuraminidase. These surface proteins are the parts of a virus that can be changed when viruses mutate into new forms. This is how they change to be able to attack the cells of new hosts or in new ways in the same hosts. They are no longer recognized as viruses that the immunological system of the host has fought before, and that allows them to mutate to forms that can evade the body's defenses again at first.In the naming convention of viruses, the protein classifications become part of the name as in H1N1; H for the Hemagglutininand N for the Neuraminidase. Hemagglutinin binds the virus to the cell it is infecting. Neuraminidase is an enzyme that lets the virus be released from the host carrier cell.There are different subtypes of viruses using the H and N nomenclature, for example the H5N1 subtype is the Avian (Bird) Flu.
What do the 'H' and 'N' stand for in influenza viruses?
hemaglutinin and neuraminidase, two surface glycoproteins of influenza that contribute the the virulence of the disease...

Where did the girl from n-dubz catch Swine Flu?
She never had swine flu, it was just ordinary flu
Is it H1N1 or the H1N1?
It is a flu (influenza) virus. All flus are caused by viruses. A virus is categorized by type such as Influenza Virus Type A, Type B or Type C. Viruses are always changing and mutating, and flu viruses are especially quick in their ability to mutate. When a mutation occurs, they are categorized further as subtypes and then to a finder degree as strains. H1N1 is a subtype of Influenzavirus A. The pandemic swine flu is further identified as A-H1N1/09 indicating the specific mutation of A-H1N1 into the type that caused the pandemic of 2009. Beyond that, the individual strains are broken down and named usually according to the year they were isolated and the location where they were first found. See the related question below for more information on how viruses are named.

What is the relationship between viruses and vaccines?
I am pretty sure that vaccines help your body grow immune to certain viruses depending on the virus
