Wanted immunogenicity typically relates to vaccines, where the injection of an antigen (the vaccine) provokes an immune response against the pathogen, protecting the organism from future exposure. Immunogenicity is a central aspect of vaccine development. [1] Unwanted immunogenicity is an immune response by an organism against a therapeutic ...

Until the 1880s vaccine/vaccination referred only to smallpox, but Louis Pasteur developed immunization methods for chicken cholera and anthrax in animals and for human rabies, and suggested that the terms vaccine/vaccination should be extended to cover the new procedures. This can cause confusion if care is not taken to specify which vaccine ...
Number needed to vaccinate (NNV) is a metric used in the evaluation of vaccines, [1] [2] [3] and in the determination of vaccination policy. It is defined as the average number of patients that must be vaccinated to prevent one case of disease. It is a specific application of the number needed to treat metric (NNT).
He then derived a vaccine by altering the infectious agent so as to make it harmless and then introducing this inactivated form of the infectious agents into farm animals, which then proved to be immune to the disease. [16] Pasteur also isolated a crude preparation of the infectious agent for rabies. In a brave piece of rapid medicine ...
The process of serial passage yields a live vaccine. There are both advantages and disadvantages to this. Most notably, live vaccines are sometimes more effective and more long-lasting than inactivated or other types of vaccines. [10] [11] However, just as the virus evolved to become attenuated, it may reverse-evolve in the host, leading to ...
The antigens and antibodies combine by a process called agglutination. It is the fundamental reaction in the body by which the body is protected from complex foreign molecules, such as pathogens and their chemical toxins. In the blood, the antigens are specifically and with high affinity bound by antibodies to form an antigen-antibody complex.
An important field of application are mRNA vaccines. Replacing uridine with pseudouridine to evade the innate immune system was pioneered by Karikó and Weissman in 2005. [ 15 ] [ 16 ] They won the 2023 Nobel Prize in Physiology or Medicine as a result of their work.
