Every year on the third Sunday in June, Kazakhstan celebrates Health Worker's Day. Its celebration was established by the Decree of the President of the Republic of Kazakhstan in 1998. Perhaps there is no profession in the world, the importance of which in human life plays a greater role than the profession of a doctor, nurse, and all medical personnel. It is health workers who help to identify a disease by symptoms and during the examination, determine its nature, build a scheme and methods of treatment, as well as carry out this treatment. For the employees of the Karaganda pharmaceutical complex «Health Worker's Day» is considered to be a professional holiday due to the fact that pharmaceutical production workers as well as health workers make a significant contribution to the health care system by providing patients with medicines in a timely manner. Karaganda Pharmaceutical Complex LLP is the first domestic innovative biotechnological pharmaceutical enterprise, and this year the complex celebrates its 10th anniversary. The motto of the company: «Biotechnology for the benefit of people». During all these years, KPhC has been responsibly fulfilling their important mission, providing the population of Kazakhstan with affordable, safe and effective medicines, producing drugs for treatment of such socially significant diseases as: oncology, hemophilia, rheumatoid arthritis, multiple sclerosis, myocardial infarction, diabetes and other orphan diseases, which have not been produced in the Republic of Kazakhstan before. On their anniversary year Karaganda Pharmaceutical Complex wanted to express the great gratitude to all health workers of Kazakhstan for their invaluable noble contribution to the development of the industry, and as a heartfelt gift organized a concert of Karaganda Jazz Band «BIG BAND», as well as leading Kazakh performers on Health Worker's Day.
