Innate Immune System Concept Map
This concept map of the innate immune system depicts pathogen exposure. By adulthood, most people have been exposed to various pathogens and developed stronger immunity. Once an antibody is produced, the body stores a copy of it so that if the same antigen appears again, the body can deal with it more quickly. Some diseases, such as measles, can be fatal if untreated, so experts advise vaccination. A person who has received the measles vaccine is unlikely to contract the disease. It is also uncommon for an unvaccinated person to contract measles again. The body stores a measles antibody in both cases. As shown in this image, the antibody is prepared to destroy the virus the next time it appears.
