Defying Death

Updated Thursday 22nd September 2005

This extract explores issues about improvements in health care, and our expectation of a longer life. It is taken from a panel discussion that took place as part of 'The Next Big Thing' TV series.

If we get ill, we expect to be made better!

As living standards have increased, the discovery of steroids and antibiotics, as well as new techniques for organ transplant and brain surgery, have transformed our expectations of doctors.

Meanwhile, vaccine programmes have wiped the Earth clean of diseases like smallpox and polio.

But new threats continue to emerge ..

High containment facilities like the Centre for Applied Microbiology Research in Wiltshire are at the front line of our defence, diagnosing and developing vaccines against any potential threat.

In the West, lifestyle is now seen as increasingly important. Even so, obesity and lack of exercise are making many of us vulnerable to chronic illnesses.

Millions of people continue to smoke.

Smoking has been linked to cancer since the 1950s and in Britain at least the message is getting through: sales of cigarettes have nearly halved since the 1970s. But in many areas of the world the danger is still not taken seriously.

The 1918-20 flu epidemic killed 20 million people - more than died in the First World War.

John Lloyd and a giant flu virus Copyrighted image Icon Copyright: Used with permission Virologist professor John Oxford believes it will happen again.

A flu monitoring network run by the World Health Organisation is doing its best to stay ahead of the game with annual vaccination programmes, aimed at keeping the ever changing virus in check. But flu and other pathogens pose a continual threat.

The idea that we could ever conquer infectious disease now seems naïve.

New diseases, like Ebola and Lassa Fever, are emerging all the time.

And to make matters worse, one of our most precious weapons in the fight against bacterial infections - antibiotics - are losing their effectiveness, as pathogens evolve and become resistant to them.

Guests

John Oxford Copyrighted image Icon Copyright: Used with permission John Oxford is professor of virology at St Bartholomew's and the Royal London School of Medicine.

An expert in viruses, he believes the study of past epidemics will provide an early warning system for the future.

John took part in the now famous expedition to Spitsbergen, on the Norwegian island of Svalbard, to uncover the bodies of a group of miners who'd died in the 1918-20 flu epidemic which killed 20 million people. The group hoped to extract the virus from preserved tissue samples buried in the permafrost.

John is also interested in the link between flu and encephalitis lethargic, a condition made famous by the film Awakenings which causes victims to sink into a comatose state.

He combines his research on influenza with clinical trials of new influenza and HIV vaccines, and antiviral drugs. He is scientific director of the college research company, Retroscreen Limited.

Ricard Peto Copyrighted image Icon Copyright: Used with permission 'Smoking kills six people a minute worldwide'

Sir Richard Peto has made his name not only as an excellent researcher, but for presenting his work in terms that anyone can understand.

He is professor of medical statistics and epidemiology at the University of Oxford, and co-director, with Professor Rory Collins, of the Imperial Cancer Research Fund Clinical Trial Services Unit (CTSU) at Oxford's Radcliffe Infirmary. Richard Peto came to Oxford with Sir Richard Doll, one of the scientists who first made the link between cancer and smoking.

The CTSU includes a group devoted to studies in China, where smoking is a growing problem.

He was elected as a fellow of the Royal Society in 1989 and knighted in 1999.
