At Houston’s Health University (United States), the potential link between certain common vaccinations and the risk of developing Alzheimer’s disease is the subject of several research studies.
In 2022, Professor Paul Schulz and his team have thus demonstrated in people over 65 years of age, 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 expanded their study to vaccinations once morest diphtheria, tetanus and polio (DTP), shingles and pneumococcal infections. They conducted a retrospective study of patients – aged 65 and over – who did not have dementia when they were included in the program and followed for 8 years.
Compared to people exempt from vaccination, their results show a reduction in the risk of developing Alzheimer’s disease by 30% among those immunized once morest diphtheria, tetanus and poliomyelitis. Then respectively 25% and 27% for those vaccinated once morest shingles and pneumococcal infections.
A key called immune system?
To explain his results, Professor Schulz suggests “the immune system is involved 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 Professor Avram Bukhbinder, one of the co-authors, adds: “Vaccines can modify the way in which the immune system reacts to the accumulation of toxic proteins which contribute to the occurrence of Alzheimer’s disease”. So many suggestions that remain to be refined and confirmed.
