“If you want to save your child from polio, you can pray or you can inoculate. ... Choose science.”
― Carl Sagan, The Demon-Haunted World: Science as a Candle in the Dark

“She limped, unaided around the house, like a bird with its wing broken. Tame, because it couldn’t fly away. All her time was taken up with managing herself, working out new ways to do things. Being a different person in the world.”
― Joan London, The Golden Age

“Though I'd never forgotten Alan, I hadn't uttered his name aloud in the many years since he'd died, back in that decade when it seemed that the greatest menaces on earth were war, the atomic bomb, and polio.”
― Philip Roth, Nemesis

“They sat on fold-up beach chairs and were talking about polio. The older ones, like his grandmother, had lived through the city's 1916 epidemic and were lamenting the fact that in the intervening years science had been unable to find a cure for the disease or come up with an idea of how to prevent it. Look at Weequahic, they said, as clean and sanitary as any section in the city, and it's the worst hit. There was talk, somebody said, of keeping the colored cleaning women from coming to the neighborhood for fear that they carried the polio germs up from the slums. Somebody else said that in his estimation the disease was spread by money, by paper money passing from hand to hand. The important thing, he said, was always to wash your hands after you handled paper money or coins. What about the mail, someone else said, you don't think it could be spread by the mail? What are you going to do, somebody retorted, suspend delivering the mail? The whole city would come to a halt.”

“We don't know what kills polio germs," Dr. Steinberg said. "We don't know who or what carries polio, and there's still some debate about how it enters the body. But what's important is that you cleaned up an unhygienic mess and reassured the boys by the way you took charge. ... You must understand that a lot of us who are much older and more experienced with illness than you are also shaken by it. To stand by as a doctor unable to stop the spread of this dreadful disease is painful for all of us. A crippling disease that attacks mainly children and leaves some of them dead -- that's difficult for any adult to accept. You have a conscience, and a conscience is a valuable attribute, but not if it begins to make you think you're to blame for what is far beyond the scope of your responsibility."

He thought to ask: Doesn't God have a conscience? ... But instead he asked, "Should the playground be shut down?"

"You're the director. Should it?" Dr. Steinberg asked.”

“Vaccination has made smallpox extinct in the wild, as well as rinderpest, a relative of measles that affects cattle and buffalo, among others. Poliomyelitis, which has in its heyday killed and maimed millions of children and adults alike, is close to eradication, with fewer than 200 wild-type cases documented in 2020. Vaccines are some of the most effective public health interventions against infectious disease.”
