A good reference-at-a-glance of when various vaccines were introduced. It is interesting to note 1945 as the first flu vaccine and the introduction of the polio vaccine in 1955. I believe these were the first ones against viruses and they do bracket our generation rather well.

Another reason they are of interest is the surge in PD following the flu epidemic in the late teens. Still another, you may remember the German scientist Braak (sp?) has shown a well-defined sequence of places that Lewy bodies show up in PD. Something goes marching along our nerve fibers like General Sherman heading for the beach. One thing that follows a similar path is the polio virus. Polio vaccines were the first to use a weakened but still living virus.
