Scientists at Oxford University have begun immunising healthy volunteers with a new Ebola vaccine.

In September last year a separate trial of another Ebola vaccine got under way in the city.

This latest trial involves 72 volunteers aged 18-50.

Initial tests in monkeys showed the vaccine, developed by Janssen Pharmaceutical Companies of Johnson and Johnson, gave complete protection against Ebola.

The volunteers in Oxford are the first humans to receive the vaccine.

Most types of cancer can be put down to bad luck rather than risk factors such as smoking, a study has suggested.

A US team were trying to explain why some tissues were millions of times more vulnerable to cancer than others.

The results, in the journal Science, showed two thirds of the cancer types analysed were caused just by chance mutations rather than lifestyle.

However some of the most common and deadly cancers are still heavily influenced by lifestyle.

And Cancer Research UK said a healthy lifestyle would still heavily stack the odds in a person’s favour.

Ebola patient Pauline Cafferkey is receiving an experimental anti-viral drug and blood from survivors of the disease, doctors in London have said.

Specialists at the Royal Free Hospital in Hampstead, where the nurse is being treated, did not name the drug.

Dr Michael Jacobs said Ms Cafferkey was in isolation and was sitting up in bed, talking and reading.

As the disease has no known cure and is unpredictable, Dr Jacobs said they would know more in a week’s time.

He said Ms Cafferkey had agreed to all the treatments and her family had been to see her.
