There are two ways to get antibodies against the flu 1) get the flu 2) get immunized. The vaccine exposes the body to the antigen without the accompanying virulent strain of the virus. The body reacts by producing antibodies, and it is the body's antibodies (not the vaccine) that protect against the flu. This approach mimics the observed protection that was seen for those that got cow pox and then did not get small pox. The vaccine is man copying a natural phenominon. Lots of medicines were develope this way.
