Human Lymphomas Linked to Tainted Vaccine

Article excerpt

University of Texas Southwestern researchers have established a link between human non-Hodgkin's lymphomas and a monkey virus carried by some people.

The study was published in the March 2002 edition of the British medical journal The Lancet. Researchers examined nearly 400 tumors and control tissues and found the viral footprint for simian virus 40 (SV40) in the tumors of 43 percent of patients with non-Hodgkin lymphoma. The virus, predominantly of the B-cell type, was present in 9 percent of Hodgkin's lymphoma cases, a significantly lower rate. The percentage of SV40-positive findings among healthy subjects and patients with other types of adult and pediatric cancers, other than bone tumors, was zero to 6 percent.

Approximately 287,000 new non-Hodgkin's lymphoma cases are diagnosed worldwide every year.

SV40 was first transmitted to humans between 1955 and 1963 in contaminated batches of polio vaccine. As many as 30 million people may have been vaccinated with the tainted serum. Persons born after 1963 also have been found to carry the virus, but scientists are uncertain how the virus was transmitted to them. …
