DNA – The Promise & The Price

January 26, 2009
"A child born in 1953, the structure of DNA has just been discovered. 1989 and this babies genetic fingerprint can be identified. The first single gene for Huntington's disease has been discovered. 2003 this child's entire genetic code can now be read and faulty genes in his DNA can be adjusted. Another birth, but this time no ordinary miracle. The babies sex and eye colour were decided before she was conceived; also her hair, the shape of her nose and her intelligence. The date of her birth? Perhaps only a few years from now. She's born from a revolution in genetics. A revolution where each new step brings new questions of ethics and responsibility. And as the promises of the science gets greater, so do the questions for all of us get bigger."

DNA – The Promise & The Price provides an excellent resource for discussing the ethical implications of advancing genetic research, focusing on; gene therapy, stem cells and cloning. The documentary examines the frontiers of genetic science, revealing how researchers attempt to fulfil DNA’s potential to help cure and prevent disease. It also questions how some aspects of these novel technologies may have significant consequences for individuals and society. Bill Paterson: “Much is promised by genetic science, the manipulation of our genes. But can it deliver? And if it does are we ready to take responsibility for meddling with the very fabric of life itself: our DNA”.

"When it comes to medical research, any medical technology

Professor Steve Jones: "When it comes to medical research, any medical technology that works, it is very quickly accepted by the public. Ethicists may not like it, scientists may not like it, but the public, if they believe it works they will accept it, and the legislation will always follow. Ethics has always followed science, it's never led it and I don't see any reason why genetics is going to be any different. Ethicists would love to tell geneticists what to do, but I'm afraid the geneticists are not going to listen."

The topics found in DNA – The Promise & The Price include: genetics; genetic diseases; gene therapy; transplantation; stem cells; and cloning can all be found in the UK National Curriculum.

The jab that can stop cancer – Dispatches

July 22, 2008

The thought of any family member dying of cancer is always emotive, and all the more so if you think you might have been able to do something to prevent the disease from wreaking havoc. In the Channel 4 current affairs series Dispatches, journalist Jane Moore considered the forthcoming campaign to treat all 12 year old girls in the UK with a vaccine that can prevent cervical cancer.

This sounds on the face of it like an excellent idea and Moore is not an immunisation skeptic, indeed she paid privately for her older daughter to have the jab, and fully expects her younger daughter to have the injection in the fullness of time. She does, however, raise a number of interesting arguments that show that the decisions about whether or not the UK should be entering into such a full-scale vaccination programme is rather more complicated. The main issues are: (1) is the vaccine safe?; (2) is the vaccine effective?; (3) will the vaccine offer false security?; (4) will it lead to greater promiscuity?; and (5) does this represent good use of NHS resources? Let’s take each of these in turn. Read the rest of this entry »
