TB Vaccine Flushes Alzheimer’s Amyloid

The BCG vaccine remodels the human brain’s immune environment via trained immunity. Tracking older adults over one year, researchers demonstrated that BCG enhances central nervous system immune cell responsiveness and lowers amyloid-beta levels in the cerebrospinal fluid of healthy individuals, offering an early preventative pathway against Alzheimer's disease.

Mandated TB vaccination predicts flattened curves for COVID-19 spread

Researchers report that if the US had adopted mandatory BCG vaccines against tuberculosis decades ago, we may not have reached death rates in triple digits for coronavirus. Countries that have a current policy mandating BCG vaccinations have significantly slower growth of both COVID-19 cases and deaths compared to countries with no mandates for the TB vaccination.

Tuberculosis BCG-based vaccine may be effective against COVID-19

VPM1002, a vaccine candidate based on the tuberculosis BCG vaccine, may be effective in protecting against COVID-19. Previous studies in mice have shown the BCG vaccine is effective at protecting against several respiratory viral infections. If effective against coronavirus, researchers hope the vaccine can bridge the time gap until a specific SARS-CoV-2 vaccine is available.
