I hear a lot about people who avoid this vaccine. Why? I have an 8 year old step child and her mother says she's not allowed to take the flu shot because she has asthma. I have breathing problems also...though I never went to the doc about it. I buy the Primetene Mist from stores. It works well for me. Sometimes I have trouble breathing at night. Im not over weight, 5'3" 128 pounds. If I take this shot will something happen to me? My mother in law was diagnosed with diabetes right after her mandatory flu shot!! I don't think I ever had this shot.
