The swine flu contains genes from swine, bird,and human. Also called the h1n1 flu of 2009.The swine flu viruses that spread among pigs aren't, the same as the human virus.
Many people have at least partial immunity to seasonal H1N1 virus,because they've been infected with or vaccinated against this flu bug.These virus ''DRIFT' genetically.that is why the flu vaccines are always beening tweaked from time to time.
H1N1 is not the usual drift variant. It came to humans from a different line of the evolution.
See if you would get your normal flu shot has NO immunity to the H1N1 virus.
Some people who may have had seasonal H1N1 before 1957 might have a little protective immunity against the 2009 virus.
