Flu vaccination may reduce risk, delay Alzheimer's disease: Study

The aim of the researchers was to pinpoint potential factors that could reduce Alzheimer's disease risk

People who received at least one flu vaccination were 17 per cent less likely to get Alzheimer's disease over the course of a lifetime, researchers said.

"Because there is no treatment for Alzheimer's disease, it is crucial that we find ways to prevent it and delay its onset," said study researcher Albert Amran from the University of Texas Health Science Centre in the US.

"About 5.8 million people in the US have this disease, so even a small reduction in risk can make a dramatic difference. We began our study by looking for ways we could reduce this risk," Amran
