They get samples from patients from labs and in the US from the Centers for Disease Control and Prevention (CDC) and then once it is decided exactly which strain of a particular flu will be best (easiest to grow quickly, most prevalent strain in the location, etc.), they grow the selected virus in eggs a lab. When they have enough virus particles to start making the vaccine, then they either inactivate them ("kill" them-these are used for flu vaccine injections) or they weaken them chemically (they make them too weak to give you the flu, these are used in the nasal spray flu vaccinations).
Because they are grown in eggs, this is why they will ask you if you are allergic to eggs before they give you the vaccine.

How vaccines prevent infection?
Vaccines do not prevent infection. Vaccines prepare the immune system to fight infection by allowing the immune system to produce antibodies to a specific invading organism, kill it, and remember it in the future. In vaccines, this organism is often weakened or dead.
