"A Paralyzing Fear: The Story of Polio in America" is a very sobering film. Today we've forgotten just how bad the disease is, as dead kids and iron lungs are mostly a thing of the past. However, in much of the 20th century, it was a horrible plague--and this film chronicles its impact and eventual eradication in the US.
The first portion of the film is a combination of a history of the disease and also a discussion of the impact of the illness--with interviews with several folks who continue to live with the effects of the disease many decades after the vaccines were introduced. The second portion is the hopeful part--when Salk and Sabin separately developed vaccines to eliminate the virus. Sadly, the vaccines offered no help to those already suffering from the disease--but over time, it's something we SHOULD see eliminated completely.
Now here I am going to get on my soap box for a bit. If you watch this film, I can't see how any clear-thinking person could rationally object to the notion of vaccines. Yet, sadly, some folks are using purely anecdotal and emotional support to encourage parents NOT to vaccinate. My answer to this...WATCH THIS FILM. If this doesn't convince you, nothing will. Seeing folks in iron lungs is enough to convince me...as well as that pesky thing called the scientific method.
