Vaccines are generally made this way:
“The influenza vaccine is made by growing influenza virus in hen’s eggs, purifying it, and completely killing it with a chemical (like formaldehyde). The influenza vaccine given as a shot is a “killed” virus like the polio, hepatitis A, or rabies vaccines. (see How Are Vaccines Made?).
The influenza vaccine is unusual in that each year a different vaccine is made. Because strains of influenza virus that circulate in the community can differ from one season to the next, the vaccine must change to best protect against those different strains. Every year in the United States, the Centers for Disease Control and Prevention (CDC) determines what strains of influenza are circulating, and makes sure that all the influenza vaccines that are made that season contain viruses that would protect against the circulating strains. For this reason, the influenza vaccine is probably the hardest vaccine to make.”

I would add that the H1N1 virus will be available as in both injection form as the “flu mist”, which is made in a slightly different way, with a live but weakened virus, instead of a dead one. It’s described here in more detail in the New York Times.
