Code recognition. The vaccine allows your cells to recognize the genes of the virus if it enters the body and allows immunity to it once recognized. You can still get the flu, with hopes that your body will fight it or at least to mitigate the symptoms if you get it. It is not 100% perfect immunity for 100% of the population.
