Early tests showed the vaccine is highly effective at breaking up the sticky protein that clogs the brain in Alzheimer’s, destroying vital connections between brain cells.

When the jab was given to mice suffering from a disease similar to Alzheimer’s, 80 per cent of the patches of amyloid protein were broken up.

The vaccine is now being tried out on 60 elderly Swedish patients in the early and middle stages of Alzheimer’s. Half of the men and women are being given the vaccine while half are being given dummy jabs.

Although the year-long trial is designed to show that the treatment is safe, the researchers will also look at its effect on the patients’ symptoms.

While the results are not due until early next year, the initial findings are promising. Dr Renner told a Zurich conference earlier this week: “I am glad to report that the vaccine is very well tolerated.”

Novartis is apparently setting up a trial here. That must be the study behind the recruiting commercials I’ve heard on local radio.

I really hope it works. Alzheimer’s scares me more than cancer. I could face death if I could still be me.
