IMMUNOTHERAPY is the newest and most advanced method for treating cancer. However, the history of immune therapy and prevention dates back centuries, all the way to the 17th century. The history of the BCG vaccine, in particular, marked its 100th anniversary in 2021.

There is no other such vaccine in the world that has been used for more than 100 years without being modified, maintaining its effectiveness and harmlessness for so many years after its discovery by the French scientists A.Calmet and C. Guerin of the Institut Pasteur - Paris, in 1921 .

A few years after the discovery of the BCG vaccine, its immunostimulating effect was also proven. For many years, this vaccine has been used in medicine as an immune ‘booster’ under the name Freund’s adjuvant.

It is precisely this immune-stimulating effect that is the basis of Prof. Spartak Hadjiev's discovery of an anti-cancer drug, awarded with several copyright certificates of invention (patents) from 1961 to 2012.

For the first time in the world, Prof. Spartak Hadzhiev applied the BCG vaccine to patients with lung cancer. For many years, together with his daughter, Prof. Nasya Hadzhieva, and his grandson, Assoc. Prof. Mihail Petrov, they developed and refined this preparation under various names—F70, HD88, H96, and others—for the treatment of all types of solid tumors in humans.
