Same procedure as every year. No shot, no flu. I do some exercise, try to get enough fresh air, fresh fruit and fresh vegetable and sprouts. In this season I use paper handkerchiefs and strictly throw away after single use.
The flu has downed a few of my coworkers, some of them more than once. They seemed to be really sick.
This winter I started using a can for nasal irrigation. It feels awkward at first but you get used to it. It reduced problems with overly dry rooms.
