Vaccine

A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe. The agent stimulates the body's immune system to recognize the agent as foreign, destroy it, and "remember" it, so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters.

Memory B cells reveal how nasal vaccines could stop respiratory infections earlier

A Science Immunology Review explains how memory B cells acquire diverse molecular, epigenetic, and tissue-specific programs that shape long-term immune protection. It highlights lung-resident memory B cells as a key target for mucosal vaccines, potentially improving control of airborne infections and reducing transmission.

BCG vaccine may remodel the human brain's immune environment

New research led by Mass General Brigham investigators suggests that the Bacillus Calmette-Guérin (BCG) vaccine - which is delivered through the skin to prevent tuberculosis - may remodel the human brain's immune environment, offering a potential biological explanation for previously observed associations between BCG vaccination and lower Alzheimer's disease risk.

Lung tumors hijack nervous system to drive cancer-related cachexia

According to the Cleveland Clinic, a quarter of cancer deaths can be attributed to one source: cachexia. Cachexia is a syndrome that accompanies underlying chronic illness and causes unwanted muscle and fat loss, reducing quality of life and sometimes even limiting treatment options.

KFF poll finds vaccine myths reach many Americans but convince few

KFF’s 2026 tracking poll found that many U.S. adults have heard common vaccine myths, including false claims about MMR, COVID-19, mRNA vaccines, and measles vaccines. Fewer adults strongly believe these myths, but a large, uncertain “malleable middle” remains, especially among those without a trusted health care provider, frequent social media users, some AI health-information users, and parents who delayed or skipped childhood vaccines.
