American scientists conducted a study on the basis of which they found that flu vaccination for several years significantly reduces the risk of Alzheimer’s disease. For people who get flu vaccinations regularly, the effect is enhanced and lasts longer.
- There is no effective pharmacological cure for Alzheimer’s disease. However, scientists are looking for ways to prevent and inhibit the development of the disease
- American neuroscientists conducted extensive research among people over 65, vaccinated and unvaccinated against influenza
- It turned out that a single vaccination can reduce by 40%. risk of developing Alzheimer’s disease for about four years

Alzheimer’s disease is one of those medical phenomena around which there are still more questions than answers. From time to time, scientists discover new ways to prevent or reduce the effects of this condition. So far, however, no spectacular results. The latest research was conducted by medics from UTHealth in Houston. They concern the link between influenza vaccines and the incidence of Alzheimer’s disease – reports medicalxpress.com.

Alzheimer’s disease mainly affects seniors
Alzheimer’s disease is a degeneration of the nervous system that causes general dementia. Its causes and formation have not been fully understood. Most often, Alzheimer’s disease affects the elderly who have reached 65 years of age, which is why it is so often associated with lower mental performance due to age. The disease process causes damage to the cerebral cortex, which in turn leads to problems with speech, memory and thinking. Alzheimer’s is a condition that develops very slowly and over time causes problems in everyday life. There are no effective pharmacological agents for it, but from time to time there are reports of various ways of delaying the development of the disease and of preventing it, for example through an appropriate lifestyle.
The Americans examined almost 2 million people
Houston neuroscientists compared the risk of developing Alzheimer’s disease between vaccinated and unvaccinated flu patients on a large nationwide sample of American adults 65 years of age and older. In total, almost 2 million people were examined. The research showed that people who received at least one flu vaccine were 40 percent more likely to develop Alzheimer’s disease in four years. smaller than in their unvaccinated peers. Detailed results of the study are published in the Journal of Alzheimer’s Disease.
«We found that flu vaccination in the elderly reduces the risk of developing Alzheimer’s disease for several years. The strength of this protective effect increased with the number of years a person received the annual flu vaccine. In other words, the rate of Alzheimer’s disease development was the lowest among those who received the vaccine regularly every year, »said Avram S. Bukhbinder, one of the authors of the study, quoted by memdicalxpress.com. He added that further research will be carried out to see if flu vaccination also has an impact on the progression of the disease in people who already suffer from it.
Not only the flu vaccine
According to the researchers, the results of the study highlight the strong protective effect of the vaccine against Alzheimer’s disease. However, the mechanisms underlying this process require further testing. “Since there is evidence that several vaccines can protect against Alzheimer’s disease, we think that this is not a specific effect of the flu vaccine,” said Dr. Paul E. Schulz, co-author of the study. In this way, he referred to earlier studies by American doctors that showed reduced risk of dementia related to e.g. with vaccines against tetanus, polio and herpes. Neuroscientists also have a plan to investigate whether there is a similar link between dementia and the COVID-19 vaccine.
