I once heard from one of the top U.S. national health officials, who had worked on flu and other vaccines, that she'd doesn't have them! So I know there are mixed reviews. Whether through good medicine or good placebo effect, I've had them since I was in school and largely avoided flu. Last winter I had what I interpret as a case of the flu muted by the flu shot; I almost went to the doctor, but finally didn't. I went to my chain drugstore today and they were out of the senior dose, but another store in the same chain wasn't, and had no line, and didn't insist I go to the back room but just did it in the waiting area. The young woman pharmacist was knowledgeable and helpful. Maybe this year I won't have any flu symptoms. All this as a reminder, for those who subscribe to flu shots but haven't had them, it's time.
