Remodelling of immune system by TB vaccine may explain its link with lower Alzheimer's risk: Study
A new study suggests that the BCG tuberculosis vaccine may lower Alzheimer's risk by remodeling the immune system to improve brain health during aging. Researchers found a correlation between the vaccine and a reduced prevalence of dementia in long-term observations.
Recent research indicates that the Bacillus Calmette-Guérin (BCG) vaccine, originally developed for tuberculosis, may have neuroprotective benefits. The study highlights how the vaccine appears to remodel the immune system, potentially suppressing the inflammatory processes associated with neurodegenerative decline.
The scientists observed that individuals who received the BCG vaccine exhibited a lower incidence of Alzheimer's disease compared to those who did not. This suggest that localized immune responses in the brain can be influenced by systemic vaccinations, providing a new pathway for exploring preventative treatments.
However, the research team emphasized that while the findings are promising, they do not yet prove a direct causal link. Further large-scale clinical trials are required to determine if these immune changes can effectively prevent or treat cognitive diseases in the general population.
