I just hope this is possible

Many years ago my son was diagnosed with leukaemia, it wasn't a pleasant time for him as he had to go through chemotherapy and spent almost 6 months in hospital plus a further 2 years on and off being treated for various illnesses as his immune system was devastated by the drugs he had to take to kill it off. There were other side effects too, the stress of one parent or another always being in hospital along side him destroyed the marriage, still, we made good friends there too yet also had to witness the death of many of their children and the misery it wrought on their lives.
We however were lucky my son is fine now, been in remission over 10 years, though it changed my life forever, still I have no regrets now on that part.

A vaccine for leukaemia is about to be tested on human patients for the first time, in a breakthrough which could offer hope to thousands.
British researchers have developed a treatment that can be used to stop the disease returning after chemotherapy or bone marrow transplant.
Eventually it is hoped the drug, which activates the body's own immune system against the leukaemia, could be used to treat other types of cancers.

The first patients will be treated in the New Year as part of a small clinical trial at King's College London.
The patients in the trial have the form known as Acute myeloid leukaemia (AML), the most common form in adults. Even with aggressive treatment half would usually find the disease returns.
The idea behind cancer 'vaccines" is not necessarily to prevent the disease. Instead, once a patient has been diagnosed, the 'vaccine' programmes the immune system to hunt down cancer cells and destroy them.
The vaccine then prompts the immune system to recognise leukaemia cells if they return which prevents a relapse of the disease.
The vaccine is created by removing cells from the patient's blood and manipulating them in the laboratory.
The cells are given two genes which act as flags to help identify the leukaemia. It effectively focuses and boosts the immune system's ability to seek out and destroy cancer cells.

This is an incredible breakthrough and a truly brilliant achievement, it will give hope to many and may even lead to more treatments and a far higher rate of recovery. With this treatment lives will no longer be disrupted and destroyed, parents will no longer have to grieve missing children. These doctors are offering hope to so many people and I wish them well and good luck with the trials.
