The shots have not been given yet. Even the military has not gotten them. The regular seasonal flu shots are in short supply. Normally I get mine at either my company nurses office, or since I've been assigned on an Army post, from the Army. This year, less than two weeks ago, they gave the "nasal" vaccination for seasonal flu. But you can't get that if you are over 50. (And its not like there aren't plenty of Army civilians who are over 50) So I got mine at WalGreens, since my doctor's office was also out. As did my coworkers because the clinic(s) they normally use were also out of the shots. My wife, who is a department chair at a small college, usually gets hers from the college, but they didn't have any either. She happened to be visiting me (long boring story) so we both got ours at the local Walgreens, since the Walgreens in far north Texas that she uses was also, out.
Since the shots (or nasal vaccinations) have not yet been given (actually I think a few places started this week) infections via the vaccination are not a factor.
Unless you use Grecian Formula right before you go in like I did and say you are 49. It worked.
