As an asthma patient, I have to have a flu shot every year. We get ours thru the local senior care group. They hold a 3 day event by appointment only. You drive into the hospital garage parking, sign the paper and the nurse administers the shot. You never get out of the car, just stick your arm out the window. This is a free program to those over 50. Might be a little tenderness for a day or so but nothing more.
