Annual vaccination against the flu virus reduces the risk of developing Alzheimer's by nearly 20 percent in adults, according to a new study by the University of Texas at the United States.

The study, recently presented at a conference of the International Association for the Prevention of Alzheimer's Disease in Adults, was conducted among 9,000 experimenters, and found that the younger the vaccine against influenza was given at a younger age, the more significant its effect was. That is, a person who received the vaccine at age 60 was less prone to the disease compared to a person who began receiving the flu vaccines at age 70. The exact effect of the vaccine among vaccinated adults is estimated at 17 percent, a dramatic rate in disease prevention.

The researcher from the University of Texas who conducted the study, Albert Amran, noted that it is not yet known why there is such a link between the flu vaccine and the prevention of Alzheimer's, and to test this further research will be needed. He said, "The data has unequivocally taught about an interesting link of this kind, so a relatively inexpensive vaccine can help many people not get Alzheimer's."

Dr Rosa Sancho, head of Alzheimer's research in the UK, said: “This is an interesting study. "It is difficult to know what the seasonal flu vaccine is and the prevention of Alzheimer's, what is the cause of the disease in general, but it is possible that people who take the vaccine are also people who are more self-sufficient and therefore less exposed to other harms that lead to Alzheimer's."

The conference presented a study by the University of Copenhagen of a million and a half people, which showed that Alzheimer's patients are 6.5 times more likely to die from any infection than other people. Any infection that affects a patient, from sepsis to mild ear infections, has dramatically increased mortality rates, regardless of the severity of the infection.
