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.

A century of safety: Aluminium vaccine adjuvants do not raise serious long-term health risks

A BMJ systematic review of 59 human studies found no evidence supporting causal links between aluminum-adjuvanted vaccines and serious or long-term outcomes such as autism spectrum disorder, asthma, autoimmune conditions, or other chronic illnesses. The most consistent adverse events were uncommon, local, self-limited persistent nodules or granulomas, likely reflecting delayed-type hypersensitivity.
