The Salk vaccine as approved in 1955, but was not widely available for several years.
Thanks for the wiki article, but what I was looking for is some credible evidence that the polio epidemic had already been decimated by herd immunity. The graph shows cycles, with high and low years. Without the introduction of the vaccine, what makes you think it wouldn't have spiked again?It took over 8 years to develop the Salk vaccine for polio, so clearly vaccines are not and never will be the means of ending an epidemic that already hit. What vaccines are good for, is preventing new ones in the future.
I'm not following the reasoning that it's a terrible idea to introduce a vaccine during an epidemic. You lost me.
