The article presents the results of a retrospective analysis of viral hepatitis B incidence in the Russian Federation from 2013 to 2017, taking into account the use of vaccines included into the National Immunisation Schedule and the Immunisation Programme in Case of Epidemic Outbreaks. The analysis of the data revealed a trend towards a reduction in the incidence of acute and chronic forms of hepatitis B in the territory of the Russian Federation during the past five years. The reduction of viral hepatitis B incidence was achieved thanks to a higher vaccination coverage of both children and adults. The article presents an overview of monovalent and combination recombinant hepatitis B vaccines licensed in the Russian Federation. It describes the WHO position on preventive vaccination against viral hepatitis B, and pays special attention to vaccination of people at risk. The article considers promising areas for improving immunobiological products for hepatitis B prevention, including new technologies used in vaccine production, development and introduction of new adjuvants or adjuvants systems, and development of therapeutic vaccines.
В статье приведен анализ эффективности и безопасности вакцин для профилактики клещевого энце-фалита (КЭ), разрешенных для применения на территории Российской Федерации. Показано, что ис-пользуемые в настоящее время вакцины КЭ отечественного и зарубежного производства обеспечивают высокую иммуногенность, безопасность и эпидемиологическую эффективность в регионах с массовым охватом вакцинацией. Все зарегистрированные вакцины соответствуют основным принципам взаимо-заменяемости по показаниям к применению с учетом возрастных ограничений, перечню медицинских противопоказаний, схемам вакцинации, составу вакцин, а также показателям безопасности, иммуноло-гической активности и эффективности. Своевременные меры специфической профилактики приводят к снижению заболеваемости КЭ в эндемичных регионах. This article provides a review on efficacy and safety of tick-borne encephalitis vaccines licensed in the Russian Federation. It highlights that both Russian and imported tick-borne encephalitis vaccines demonstrate high immunogenicity, safety and epidemiological effectiveness in regions with high vaccine coverage. All licensed tick-borne encephalitis vaccines meet interchangeability criteria in terms of indications for use (with due regard to age limits), medical contraindications, vaccination schedules, vaccine composition, as well as safety, immunological activity and efficacy parameters. Timely and specific prophylaxis help reduce the incidence of tick-borne encephalitis in endemic regions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
