Not this caliber there wasn't. I'll guarantee you that Polio was foremost on our minds in the 50s and I don't recall any unusual one in 68, and I was in college and in the service during the first and last parts of those years. 2009??? Nope don't remember that one. There are flu's and there are flu pandemic. Those two are not the same thing. There is a flu that goes around every year. This is flu season and the reason why we get flu shots every year. This is a whole nother animal that the world hasn't seen since 1917, 103 years ago.
