The Innate Immune System

What is the innate immune system? It is the part of our immune system that serves as our first line of defense against pathogens, like viruses and bacteria. The skin is part of the innate immune system. It routinely deflects microbes, but sometimes a germ gets inside the body through a cut in the skin or through entry points, like our noses or mouths. Innate immune system cells, like macrophages, neutrophils and natural killer cells are the first responders when germs invade the body. They work together to destroy to microscopic attackers and activate our adaptive immune system. The innate immune response is non-specific, so the germ may be stopped or limited but our body does not generate immunologic memory to protect us against future infections.

The animation, “The Adaptive Immune System,” depicts how the immune system generates a more targeted response to pathogen, compared with the innate immune response. The adaptive immune system is responsible for the development of immunologic memory, which protects against future encounters with the same pathogen. Watch now: • The Adaptive Immune Sy... .

The Vaccine Makers Project (VMP) is the classroom-based program of the Vaccine Education Center at the Children’s Hospital of Philadelphia (VEC at CHOP). The Center’s team is composed of scientists, physicians, mothers and fathers devoted to the study and prevention of infectious diseases. The Center was launched in October 2000 to provide accurate, comprehensive and up-to-date information about vaccines and the diseases they prevent. The VMP program is committed to public education about vaccine science via scientifically supported, historically accurate, and emotionally compelling content.
