my mom wants me to get the flu shot this year because of how thin i've gotten and she says that my immune system is probably weak and i could catch the flu this winter. here's my problem, i heard that you can sometimes get the flu from the flu shot. does anyone know if this is true? i can't see getting the flu shot if it is going to give me the flu. i do not want to get the flu!! i'm scared to get the flu.
