ANSC 1001 Study Guide - Final Guide: Medical Sign, Coronavirus, Protein Subunit
Document Summary
Safe version of a disease-causing organism or protein. Intended to create the response necessary to establish immunity without causing disease. Must contain the actual antigen in order to stimulate antibody production without causing clinical signs illness: killed virus vaccine. There is virtually no chance it could once again become virulent. The virus cannot be shed in the environment, unlike some other vaccine technologies. The immune response it creates is relatively weak and short-lived. A component called an adjuvant is often added to killed vaccines: adjuvants. Boost the immune response to expose the body to the foreign protein for as long as possible: modified live vaccine. The virus has been modified or changed from its original state. The process by which the virus is tamed is called attenuation. This can be done by growing the virus in unusual conditions. A living virus that has reduced ability to cause disease.
