Why do we have to get a diffrent flu vaccine every year?
The influenza virus is in a continuous state of mutation. Each year different strains become prominent. If the educated guesses of the disease control folks are accurate, they can produce a vaccine that will be aligned with the proteins on all of the most common strains for a given year.
