Vaccines
substance used to stimulate the production of antibodies and provide immunity against one or several diseases, agent of a disease, its products, or a synthetic substitute
(Redirected from Vaccine)
Vaccines are biological preparations that provides active acquired 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, its toxins, or one of its surface proteins. The agent stimulates the body's immune system to recognize the agent as a threat, destroy it, and to further recognize and destroy any of the microorganisms associated with that agent that it may encounter in the future. In the 2000s, vaccine misinformation developed, with opponents of vaccination spreading false claims through various media.
