At Houston’s Health University (USA), the potential link between certain common vaccinations and the risk of developing Alzheimer’s disease is the subject of several studies. In 2022, Professor Paul Schulz and his team thus demonstrated in people over the age of 65, a 40% reduction in the risk of developing this disease, in the 4 years following the injection of a dose of flu vaccine. compared to unvaccinated people.
This time, the scientists extended their study to vaccinations against diphtheria, tetanus and poliomyelitis (DTP), shingles and pneumococcal infections. They conducted a retrospective study with patients – aged 65 and over – who were not suffering from dementia when they were included in the program and followed for 8 years. Compared to people without vaccination, their results show a 30% reduction in the risk of developing Alzheimer’s disease among those immunized against diphtheria, tetanus and poliomyelitis. Then respectively 25% and 27% for those vaccinated against shingles and pneumococcal infections.
A key called the immune system?
To explain his results, Professor Schulz suggests “a questioning of the immune system in the dysfunction of brain cells occurring in Alzheimer’s disease. Vaccination would thus have a more general effect likely to reduce the risk of developing this condition. And Prof. Avram Bukhbinder, one of the co-authors, adds: “Vaccines can modify the way the immune system reacts to the accumulation of toxic proteins that contribute to the onset of Alzheimer’s disease”. So many suggestions that remain to be refined and confirmed.
Soon an effective treatment against narcolepsy?
