According to the National Vaccine Information Center:

“This is the “Cutter Incident” in 1955. All those people in “iron lungs” got polio from the polio vaccine. All of them!!! Every last one of them!! The vaccine caused 40,000 cases of polio, severely paralyzed 200 children and killed ten. It’s explained at the 18:06 minute mark of “Exposing the Truth about Vaccines” with Dr. John Bergman. Yet this is the photo they always use to promote the polio vaccine!!”
