SV40 : Mesotheliomas [#permalink]

Show Tags

New post 17 Aug 2008, 09:52
Although exposure to asbestos is the primary cause of mesothelioma, a slow-developing cancer, reserchers believe that infection by the SV40 virus is a contrubuting cause, since in United States 60 percent of tissue samples from mesotheliomas, but none from healthy tissue, contain SV40. SV40 is a monkey virus; however, in 1960 some polio vaccine was contaminated with the virus. Researchers hypothesize that this vaccine was the source of virus found in mesotheliomas decades later.

Which of the following, if true, most stongly supports the researchers' hypothesis?

a)SV40 is widely used as a reserach tool in cancer laboratories.
b)Changes in the technique of manuyfacturing the vaccine now prevent contaminationw with SV40.
c)Recently discovered samples of the vaccine daitng from 1960 still show traces of the virus.
d)In a small percentage of cases of mesothelioma, there is no history of exposure to asbestos.
e)In Finland, where the polio vaccine was never contaminated, samples from mesotheliomas do not contain SV40.

Please advise with explanation.

VACCINE WAS NOT CONTAMINATED=>SAMPLE DONT CONTAIN SV40...
SUPPORTS THAT IF IT WERE CONTAMINATED,SV40 WOULD HAVE BEEN PRESENT.

IMO E

IMO E)

E) clearly states that if polio vaccine was not contaminated then SV40 did not exist.

E

hypo of scientists : vaccine was contaminated with virus that lead to SV40

no vaccine - > no virus - > no SV40 (thats what E says)
