Genetic-Associated Reduced Efficiency and Safety of Cohort Immunization
Journal Title: Актуальна інфектологія - Year 2015, Vol 1, Issue 6
Abstract
Low efficiency of cohort immunization and postvaccinal complication are not always connected with vaccine unsatisfactory quality or violation of vaccination requirements by medical workers. The paper demonstrates that epidemic dynamics, disease clinical manifestation typical for it, efficiency and safety of immunization, postvaccinal complications incidence also closely interrelate with relative quantity of persons with anomalies (polymorphism) of immune response genes and physiologic systems protected from disease development. Polymorphism of these genes has a spontaneous development by single nucleotide polymorphism and deletions forming apportioning in next generations according to Mendel’s laws. Polymorphism accumulation involved into infectious diseases pathogenesis is ironically a result of progress in control of contagious cycle infections, particularly natural smallpox. There was taken off a selective pressure from a population that extracted persons unable to react effectively on infectious agents invasion. Velocity of polymorphism accumulation is growing in relatively genetically homogeneous population (inhabitants of island countries) and in populations with typical intermarriages. It is impossible to refuse from control of contagious infectious agents. So we should expect of increase of registered postvaccinal complication associated rather with human genome peculiarity than with other reasons. That causes the necessity to adjust a strategy of immunization of various cohorts and methods for determining the reasons of postvaccinal complications. The paper also describes polymorphism of immune response genes significantly associated with low effectiveness of vaccination against measles, rubella, epidemic parotitis, B hepatitis and complications after live smallpox and tuberculosis vaccine Mycobacterium bovis BCG.
