That more than a couple of percent knew the inventor of the Polio vaccine was a surprise to me.
It's multiple choice. I'll admit that I didn't know his name off the top of my head when reading the question. But I kind of recognized it when I saw it and I definitely knew it wasn't one of the other 3 options.
That's a generational thing. There isn't a single member of my generation that doesn't know. We lived through it; my Uncle died of it; we took the first vaccines when they came out.
And as someone who's almost 55, we learned it from your generation, the memories were still very fresh.
And probably because I'm into these sorts of things, I also remember Sabin, who created the oral vaccine that was essential for eradication, as Wikipedia puts it:
The Sabin vaccine worked in the intestines to block the poliovirus from entering the bloodstream. In the intestines, Sabin had discovered, the poliovirus multiplied and attacked. Thus, the oral vaccine broke the chain of transmission of the virus and allowed for the possibility that polio might one day be eradicated.
I mention that in part because the only other vaccine developer I can remember (well, not counting Pasteur who's famous for a whole lot of things) is Jenner.
