Swine flu. We have it here. There have been over 2,000 cases, so far. That’s about ten percent of the student population, which, according to the attendance in the classes I teach, sounds about right. I am washing my hands like crazy. I haven’t gotten the flu vaccine, but I don’t usually do that until later in the fall. I don’t think they’re available here yet even if I was motivated to get them. So, like I said, my defense is hand washing. Part of me wonders if I should just forgo the vaccine. If I get the flu, maybe I will build up an immunity to the more severe cases that will come along. I read that the flu vaccine in the past does offer some immunity to flu viruses in the future. That’s nice, since I’ve gotten the vaccine for several years.
