Bill to prevent experimentation on human fetuses was heard again today. Opposing the bill was Dr. Charles McCann, university surgeon and cancer researcher, who says use of embryonic human tissues is indispensible to research now being done to isolate disease viruses such as cancer and multiple sclerosis. He says the bill places serious restrictions on medical research, and that it should be rewritten and made much less restrictive. People who wrote the bill are imposing far-reaching legislation that will affect the future health outlook for people who are alive now and for generations to come. Dr. Chet Anderson of the MMA says if this type of restriction had been around over the last 30 years we would not have practically eradicated polio, smallpox, and prevented rubella. It is a necessity for this type of research to continue.
