I haven't heard anything on that but I walked through the mall today by my place and saw many of ole geezers sitting around waiting for their shot at a,"flu shot fair." Chances are I won't be seeing most of them after the winter, shot or not.
Another thing. Some people get carried away with this flu thing. They get a sniffle and some coughing with runny nose, they say they caught the flu. Most of what I see are people not dressing for the weather. Last Sunday I took my buddy and his son to the arena for hockey practice. When it was over the kids were walking outside with beads of sweat running down their heads without head covering. I gave my buddy heck because his son was one of those kids and should know better. The son always refused to wear head covering and just last year he had developed pneumonia.
