The brief
The Bacillus Calmette–Guérin (BCG) vaccine is being studied for its potential to reshape the human brain's immune response and reduce the risk of Alzheimer's disease. Results from two open-label clinical trials indicate that this immunotherapy reprograms central nervous system (CNS) immunity.
Coverage from Nature, MedPage Today, and Medical News Today emphasizes that the vaccine alters Alzheimer's biomarkers. IFLScience and News-Medical report that researchers are now uncovering the mechanisms behind how the vaccine remodels the brain's immune environment.
Future attention will likely focus on the specific clues regarding why the BCG vaccine reduces risk and the long-term implications of these altered biomarkers.
