前面的道理已经讲的很透了,我只在这里更正一下双方支持者都出现过的一个错误:问题most strongly supports the researchers' hypothesis里的hypotheis没有双重含义,只是"that this vaccine was the source of the virus found in mesotheliomas";稍微仔细看看就知道,第一这里用的是单数,第二文中明确指出的hypothesis只有这一处。
The SV40-like sequences are suggested to have arisen from contaminated polio vaccines. Millions of people in the United States and most European countries were inoculated with SV40-contaminated polio vaccine in 1955-1963. However, in Finland, where polio vaccination started in 1957, no SV40-contaminated vaccine was used. We used a polymerase chain reaction-based method to test for the presence of SV40-like sequences in DNA extracted from the frozen tumor tissues of 49 Finnish mesothelioma patients, most of whom had been occupationally exposed to asbestos. All of the Finnish tumor tissues tested negative for SV40-like sequences. The results suggest that the SV40-like sequences detected in mesothelioma tissue in some previous studies may indeed originate from SV40-contaminated polio vaccines.
