Growing at host body temperature (37 °C (99 °F)) is an important requirement for pathogenesis. Some strains of S. schenckii are restricted to growing at 35 °C (95 °F) and consequently usually cause disease only on the skin as it is cooler than the body's interior. Those that are capable of growth at body temperature are more often ...

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 ...
Active immunization is the induction of immunity after exposure to an antigen. Antibodies are created by the recipient and may be stored permanently. [citation needed]Active immunization can occur naturally when microbes or other antigen are received by a person who has not yet come into contact with the microbes and has no pre-made antibodies for defense.
The influenza vaccine comes in two forms, the inactivated form which is what is typically thought of as the "flu shot", and a live but attenuated (weakened) form that is sprayed into the nostrils. it is recommended to get the flu shot each year since it is remade each year to protect against the viruses that are most likely to cause disease ...
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 ...

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.
