Study Notes
Evolution of Immunity Concept
- In ancient Rome, "immunity" referred to legal protection for senators against prosecution, highlighting an early form of immunity as an exemption.
- The modern definition shifted to biological immunity, protecting bodies from diseases and infections.
Historical Practices of Immunity
- Ancient China practiced early immunization by having children inhale powdered lesions from smallpox patients, a precursor to vaccination concepts.
- Greek historian Thucydides noted that survivors of the Athenian plague did not fall ill again, suggesting natural immunity and inspiring future research.
Edward Jenner’s Breakthrough
- Edward Jenner observed that milkmaids infected with cowpox did not contract smallpox, leading to a groundbreaking idea for vaccination.
- Conducted a landmark experiment injecting cowpox material into a young boy, who subsequently remained immune to smallpox, marking a significant advancement in immunology.
Advancements in Scientific Immunology
- Researchers Emil von Behring and Shibasaburo Kitasato discovered that blood serum from immunized animals could confer immunity to non-immunized subjects.
- This revelation in the late 19th century led to von Behring receiving the first Nobel Prize in Physiology or Medicine in 1901, underscoring the importance of serum therapy.
Ongoing Research and Recognition
- Since those early discoveries, approximately 17 Nobel Prizes have been awarded in immunology, recognizing scientists’ contributions to understanding and enhancing immunity.
- Current awareness of immunity continues to evolve, prompting questions about public understanding of this vital biological defense mechanism.
