Because the virus mutates and the vaccine that protects one year against the prevalent may not give protection for next.
Each year the manufacturers work ahead of time to produce vaccines to protect against relevant strains for that year.

What are you babbling on about?
We have a number of vaccines against the flu. The flu is caused by a virus. It has a number of strains. We vaccinate against the strain that was most prevalent in the Southern Hemisphere during their winter. A flu vaccine doesn't offer 100% protection against the flu, but it offers a lot more protection than not having a vaccine at all.
Wrong.....Flu is the body's reaction to being infected with a specific virus. If there was no reaction the person wouldn't get ill.
The virus causes the body to react in a way that gives the symptoms we call flu, but the virus itself is not flu
I'll try to give a similar example. Some people get hayfever usually caused by grass pollen. Grass pollen is not hay fever, but for sufferers breathing pollen to your nostrils in even a small amount can cause a lot of unpleasant symptoms, runny nose , cough etc. Its the body's reaction to pollen, but the pollen itself is not hay fever but it causes hay fever
