BCG vaccine may be a weapon against Alzheimer’s disease

New research suggests the century-old BCG tuberculosis vaccine may also reduce Alzheimer’s disease risk. Originally developed against TB by Calmette and Guérin and proven highly effective, this vaccine now appears to have broad immunotherapeutic benefits. Clinical trials have demonstrated its potential in lowering Alzheimer’s and dementia risks, with studies indicating a 20-45% decrease in older patients with bladder cancer. Studies call for more research to validate these promising results, given Alzheimer’s growing prevalence and economic impact.
