[Problems and prospects of gene therapeutics and DNA vaccines development and application].

The review is summarized foreign publications devoted to different aspects of DNA vaccines and gene therapeutics' biological safety. In spite of incomprehension in their action, numerous prototype DNA-based biopharmaceuticals are in advanced stages of human clinical trials. This review is focused on some safety concerns of gene formulations vaccines relate to toxic effects, vertical transmission possibility, genome integration complications, immunologic and immunopathologic effects and environmental spread. It is noted that necessity of national regulatory documents development related to gene therapy medicinal products is significant condition of their application to medical practice.
