{{cquote|Can you explain why better nutrition and sanitation eliminated polio in 1954-55 but waited until 1964 for measles? It's very sneaky of nutrition and sanitation to kick in only at the same year vaccines are released.|||Andrew L.<ref>[https://www.facebook.com/hatepseudoscience/photos/a.167664610048076.39182.163735987107605/424222604392274/?type=1&theater Here's an answer to the popular anti-vax trope that better nutrition and sanitation are responsible for the decline of vaccine-preventable diseases.] by "I fucking hate pseudoscience" (December 8, 2014) ''Facebook''.</ref>}}
Many anti-vaxxers claim that better sanitation is the true reason that rates of diseases were massively reduced around the time. This is very questionable. As noted by the quote above, not all diseases decreased at the same time or the same rate, suggesting that they were not prevented by the same changes. "Sanitation" is not a binary -- for example, modern toilets and plumbing, which hugely helps in preventing waterborne diseases such as cholera, took many decades to reach even a majority of citizens in any country. And polio has been nearly eradicated not by eliminating world poverty and lack of sanitation, but via vaccination -- so even if sanitation ''helps'', it is clear that vaccines ''work''.
