"•Some evidence suggests that receipt of SV40-contaminated polio vaccine may increase risk of cancer. However, the majority of studies done in the U.S. and Europe which compare persons who received SV40-contaminated polio vaccine with those who did not have shown no causal relationship between receipt of SV40-contaminated polio vaccine and cancer."
And who has the records of which vaccine someone had administered in the late 50's? For that matter, who has the records of who received the Sabin vaccine in the early 60's when it was administered at clinics held in the public schools for the general population?
That disclaimer means absolutely nothing.
“”have shown no causal relationship “”
For their studies, they never do!!! Makes it so convenient.
