“Let’s go back to the early 1900s. Scurvy was on top of the list [of diseases], and it was the same rate of disease and declined at the same rate as tuberculosis, cholera, scarlet fever, yellow fever, measles. People died from all these infections. But they died from scurvy at the same rate. Once the death from scurvy started dropping, we see all these infectious diseases dropping at the same rate.
Why aren’t people dying from scurvy anymore? Well, we have trucking. We have railroads. We’re getting produce, lemons and limes in the winter. We also have sewage treatment. The advent of sewage treatment was huge in this country… huge anywhere. … Having water that’s not going to give you diarrhea so you’re not constantly being bombarded with infectious agents.
In this country, we did not vaccinate away cholera. We didn’t vaccinate away tuberculosis. So there’s a lot of things that people think of that we vaccinated away but we never did in this country.”
