In 2002, the journal Lancet published compelling evidence that contaminated polio vaccine was responsible for up to half of the 55,000 non-Hodgkin's lymphoma cases that were occurring each year. Such statistics are never discussed when the success of a vaccine program is announced, yet it is a health outcome of the vaccine that should be taken into account

Dr. Jonas Salk developed the first polio vaccine in 1955. He used dead polio viruses. In 1976, he testified before a congressional committee that the live-virus (oral) vaccine (for practical purposes, the only kind used in America since the early 1960s) was “the principal, if not the sole cause” of all reported polio cases since 1961.

The next year Dr. Salk made this statement in Science magazine:

“The live polio virus vaccine has been the predominant cause of domestically arising cases of paralytic poliomyelitis in the United States since 1972. To avoid the occurrence of such cases, it would be necessary to discontinue the routine use of live polio vaccine.”—Dr. Jonas Salk, Science, April 4, 1977.

"Polio has not been eradicated by vaccination, it is lurking behind a redefinition and new diagnostic names like viral or aseptic meningitis. When the first, injectible polio vaccine was tested on some 1.8 million children in the United States in 1954, within 9 days there was huge epidemic of paralytic polio in the vaccinated and some of their parents and other contacts. The US Surgeon General discontinued the trial for 2 weeks." Doctor Viera Scheibner PhD

how many examples we need? I didn't even mention SV40
