Ten yeas have passed since the publication of the first edition, and there have been many advances in our understanding of the BCG vaccine. Hence, we added contents about the safety and use of the BCG vaccine and its application to other diseases in this second edition, in addition to a revision of the contents of the first edition. The authors of this book are experts in the fields of BCG and TB research.



　This book is the only book that covers basic, clinical and epidemiologic studies of the BCG vaccine systematically. No other book covers the TB vaccine so comprehensively, from its birth up to future vaccine development. Finally, TB is not a past disease and has not been eradicated yet, it can still be considered a pandemic. We would be extremely thankful if this book is useful for persons engaged in the eradication of TB by helping them futher their understanding of the TB vaccine and its future prospects.
