午夜剧场

The word "immunity" has become rapidly popular over the last few years. On train advertisements, one often sees things like "supplements to boost immunity," and programs like Chico-chan's "National Unified Immunity Countermeasures Test" are being broadcast. Why have Japanese people suddenly become so interested in "immunity"? Naturally, it seems that the COVID-19 pandemic has had a strong influence. Interest in vaccines is also high, and their strong side effects have become a topic of conversation along with their effectiveness.

Immunity, as the characters suggest, means "to be exempt from pestilence"—in other words, it is our body's system for countering infectious diseases. We tend to think that the stronger such a grateful defense system is, the better. It is true that antibodies, discovered by Shibasaburo Kitasato, are currently used as therapeutic agents for various diseases, and Professor Tasuku Honjo won the Nobel Prize in 2018 for cancer immunotherapy. As a trump card to end the COVID-19 pandemic, infectious disease experts and doctors were recommending that people "get vaccinated more and more," as many as five or six times every three months. However, I wonder: did they study immunology? In student practicals at the School of Medicine, we have students experience firsthand that immunizing mice to produce antibodies can, depending on the conditions, cause anaphylactic shock and death. Various immune diseases are always questioned in the National Examination for Medical Practitioners. In other words, immunity has both light and shadow, and it is built upon a precise and exquisite balance of the accelerator and the brake.

The reason I decided to write this book is that while I want to convey the greatness of "immunity" and the potential for its future development to many people, I also felt a sense of crisis regarding the current situation where a lot of information that does not reflect a correct understanding of immunology is being circulated. I want accurate knowledge to be known as widely as possible, especially by young people. I wrote this with the hope that they will use it as material to think and judge for themselves.

Since it is an introductory book, I intended to write it as clearly as possible, but on the other hand, I explained the important principles of immunity head-on so as not to be ambiguous. Therefore, a certain level of basic knowledge in biology will likely be required to read it through. Although it is titled a "Super" Introduction, it is not a "super" easy introductory book. I would be grateful if you could view it as a book that "goes beyond" (super) an introduction.
