The conducted research shows that now HIV- infection is associated at Russians with consumption of drugs and insufficient social responsibility of youth and also with risks at delivery of health care and implementation of cosmetic procedures. Authors note that in spite of the fact that development of vaccine against HIV-infection/AIDS is represented to the interviewed Russians one of possible ways of overcoming epidemic, respondents perceive personal participation in vaccination against HIV- infection/AIDS as a high-risk step.

Objective: to assess parents’ attitude toward vaccines and the degree of their awareness about vaccination using a specially designed questionnaire. Materials and methods. We conducted an anonymous survey of 360 parents who stayed in a hospital to take care of their children. The questionnaire included 34 questions on parents' awareness about vaccination and their general attitude toward vaccines. Results. Our survey demonstrated that 282 children were partly or fully vaccinated, whereas 78 children were not vaccinated. A total of 79% of parents believe that vaccination is the most effective method of preventing infectious diseases. The majority of parents (80%) understand that vaccinated children are less likely to develop severe illness than those who have not been vaccinated. Almost two-thirds of parents (60%) responded that they would like to expand their knowledge on immunization and believe that measures taken to inform people about vaccines are insufficient. Results. Our findings suggest that the majority of parents have a generally positive attitude toward vaccination. However, our respondents demonstrated lack of awareness about vaccines. Therefore, educational events should be planned to raise awareness about vaccination among parents.

The goal of study was the epidemiological substantiation of optimization measures of a vaccinal prevention of whooping cough in the Russian Federation. Materials and methods. The retrospective descriptive epidemiological research has been conducted by analysis of the official statistical data on the whooping cough case rate (form No. 2) in 2005-2017 in the Russian Federation, as well as the data about preventive whooping cough inoculations (forms No. 5, No. 6) in 2005-2017 and about epidemic outbreakes in 2017 (form No. 23-17). The assessment of an economic damage from whooping cough in 2005-2017 has been carried out. Results. The following adverse characteristics of a modern epidemiological situation on whooping cough in Russia are shown: long-term recurrence of epidemic process, tendency of rising of a case rate of children of 0-2 years; high percentage of children of preschool and school age among whooping cough cases; prevalence among the patients with whooping cough of the children who have been vaccinated against this infection previously, epidemic outbreakes in children's collectives, the stability of a case rate of teenagers and adults with prevalence of the mild and the erased clinical forms of this infection. The risks due to weaknesses of the whooping cough vaccinal prevention are noted: the insufficient immunization coverage owing to falce contraindications and refusals of parents of vaccinations of children, noncompliance with terms and intervals between inoculations, lack of domestic vaccine for revaccination of children at the age of 5 years and older. Conclusion. It is necessary to introduce in the national vaccination schedule a preschool booster dose for children at the age of 6 and adolescents at 14 years with the combined reduced antigen content tetanus-diphtheria and acellular pertussis vaccines as well as the inoculations of this vaccine according to epidemiological indications to health workers, employees of educational institutions. A revaccination against whooping cough is recommended as “cocoon” for the persons contacting to not vaccinated child under 1 year of age.

© Russian Association of Endocrinologists, 2018. Influence of vaccination on the risk of developing diabetes mellitus type 1 (DM1) has been studied by different researchers for several decades. In rodents, vaccination can prevent development of DM1. This review summarises existing literature and discusses the results of a 2016 meta-analysis, pertaining to vaccination and DM1. No vaccines appear to increase the risk of DM1. Additional investigations are needed to determine if vaccines can be considered protective against DM1. Patients with DM1 are at increased risk of morbidities from controllable infections. Children with DM1 should receive regularly-scheduled vaccinations; choice of vaccines and inoculation with non-regular vaccines should be determined on an individual basis. We present basic principles surrounding vaccination in patients with DM1 and analyse the role of the paediatric endocrinologist in increasing vaccination uptake in children with DM1.

In adult patients with rheumatoid arthritis (RA), mortality caused by respiratory infections is 2-5 times higher than in the population. One of the frequent infectious complications in the course of treatment with tocilizumab, the first-choice drug for treating systemic juvenile idiopathic arthritis (sJIA), is pneumonia characterized by a poor clinical picture, normal values of laboratory indices of the disease activity (ESR, C-reactive protein) with pronounced changes in the lungs revealed by computed tomography. In case of acute respiratory infection in children with systemic JIA, immunosuppressants and genetically engineered biological preparations (GEBP) are discontinued. This often leads to an exacerbation of the underlying disease and the progression of a pathological process. At present, vaccination against pneumococcal infection in Russia is not included in the standard for managing patients with rheumatic diseases. Studies of the safety and efficacy of vaccination with 13-valent pneumococcal conjugate vaccine (PCV) in patients with sJIA receiving genetically engineered biological preparations were not conducted. Clinical Case Description. The article shares the experience of vaccination of a girl aged 9 years with a 13-valent PCV that was conducted in the course of a scientific investigation, which studied the efficacy and safety of vaccination of children with systemic JIA prior to prescription of GEBP tocilizumab. Vaccination did not cause a deterioration in the course of the main disease (1 month), led to a reduction in the incidence of acute respiratory infections (from 4 to 1 time within 6 months before and after vaccination), and discontinuation of antibacterial drugs within 6 months after vaccination. Conclusion. The safety of a 13-valent PCV in a child with sJIA and a decrease of the incidence of respiratory diseases after vaccination, their complications, and the use of antibacterial drugs have been shown.

Assessment of the surveillance and control over rabies in the Russian Federation in order to determine the main directions of improving these systems under modern conditions. Materials and methods. Data of rabies surveillance in the Russian Federation in 2000–2017 were used, as well as official statements and governmental reports of the Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing and the Federal Service for Veterinary and Phytosanitary Surveillance, epidemiological descriptive-evaluative methods and GIS technology. Results. The current situation with rabies in the Russian Federation has been specified, which is characterized by a decrease of human morbidity rates against the background of a growth of rabies cases found in animals. Central Russia and the Volga region are among high-risk territories, where the maximal intensity of epizootics among wild carnivores has been observed since 2014. As has been shown, the existing rabies surveillance system permits to determine risk territories, groups, cohorts and time periods. On the other hand, there are problems related to the epidemiological diagnostics and low awareness of the population. Conclusion. Successful surveillance and control over rabies in the Russian Federatiuon under modern conditions requires improvement of the normative-legislative basis, professional preparation of specialists, further scientific research, and also consolidation of resource provision and inter-organisational interaction.

The review is devoted to the analysis of pertussis incidence of children in the age group of 5-7, as well as strategies of DTP immunization with the help of the drugs in foreign countries. Mass vaccination against pertussis began in the middle of the 20th century, which contributed to a reduction in incidence and mortality rate from this infection. However, in the last decade, there has been an opposite tendency of increasing incidence of patients among children under school age, school age and adults. Atypical forms of the disease and complications due to ARVI, respiratory mycoplasmosis and cytomegalovirus infections are described in the review. Various strategies for the use of whole-cell and acellular pertussis vaccines as part of DTP drugs are described, as well as the epidemiological effect of introducing an additional booster dose of vaccine to children under school age. The expediency of revaccination of children aged 6-7 in Russia is argued, which can help to reduce the overall incidence of pertussis. The research materials related to the study of the properties of acellular anti-pertussis vaccine, such as immunogenicity and safety in comparison with whole-cell vaccine, are analyzed. The main drugs and their composition, which are used to vaccinate children against pertussis, are described in the review. It is assumed, that the increase in the incidence among children and teenagers, with the appearance of atypical forms of pertussis, is associated with a number of factors, such as the spread of new genotypes of Bordetella pertussis bacterium, emerged from mutations, as well as short duration of immunity after vaccination with acellular drugs, in comparison with whole-cell, and the use of more modern methods of detecting the pathogen. The mechanisms of the immune response due to different types of pertussis vaccines are also reviewed. It is concluded, that revaccination of children aged 6-7 with an additional fifth dose of an acellular vaccine against pertussis, as part of the DTaP instead of the Td drug, which is regulated in the National Calendar of preventive vaccinations, will have a favorable effect on the epidemic situation with pertussis infection in Russia.

The aim of this study was to assess long-term effects of pneumococcal vaccination with 23-valent polysaccharide vaccine (PPV23) and 13-valent conjugate vaccine (PCV13) in patients with bronchial asthma. Methods. One hundred and three patients with mild to severe asthma were involved. They were randomly assigned to vaccination with PCV13, or PPV23, or PPV23 followed by PCV13, or vice versa. Clinical efficacy of vaccination was evaluated using number of asthma exacerbation a year before and 1 and 4 years after the vaccination; need in antibiotics a year before and 1 and 4 years after the vaccination; and number of hospitalizations due to asthma exacerbation a year before and 1 and 4 years after the vaccination. Results. In a year after vaccination, number of patients who had not experienced asthma exacerbation increased significantly in PPV23, PPV23/PCV13, and PCV13/PPV23 groups (p < 0.01 to p < 0.001). In 4 years after vaccination, number of patients without exacerbations increased significantly in PCV13/PPV23 group only (48.1%; p < 0.01). Number of patients who did not require hospitalization due to asthma exacerbation increased significantly in PCV13 group only (81.8%; p < 0.05). Conclusion. The authors proposed a hypothesis of impact of pneumococcal vaccines on immunopathogenesis of bronchial asthma. The authors consider vaccination against pneumococcus using PCV13 followed by PPV23 should be a part of the basic therapy of asthma.

Objective - to evaluate the possible epidemiological and economic efficiency of pneumococcal vaccination in men with different chronic diseases. Material and methods. A prognostic (Markov) model was constructed based on the data available in the literature. The estimated efficiency of pneumococcal vaccination in reducing mortality, preventable diseases, and economic damage over a 5-year period was evaluated in able-bodied men. According to official statistics, the group at high risk for pneumonia in the Russian Federation includes 21,575,887 able-bodied men. The sources of data on the cost of the disease were governmental tariffs in the compulsory health insurance system in 2016 and those of vaccination cost were the results of competitive bidding for the procurement of 13-valent pneumococcal conjugate vaccine (PCV13). Results. The results of extrapolation of data from Russian and foreign studies in patients with chronic respiratory diseases, circulatory diseases, or diabetes mellitus showed a significant reduction in the risk of complications due to the underlying disease (RR=0.58; p<0.05), the number of hospitalizations (RR=0.02; p<0.05), and expected postvaccination mortality. The cost of vaccination in the assessed patient group was 25,869.5 million rubles. The use of PCV13 significantly reduces the number of exacerbations and, accordingly, hospitalizations, which saves about 14,359.9 million rubles in each subsequent year after vaccination. Thus, the total budget savings can reach 2,850.3 million rubles just during 2 years. A single dose of PCV13 will save at least 61,702 lives over 5 years. Conclusion. The results of this investigation suggest that pneumococcal vaccination has high epidemiological and clinical efficiency in able-bodied men with chronic diseases. This intervention reduces morbidity rates, the number of exacerbations and hospitalizations, as well as deaths in the vaccinated group, and it is a cost-effective investment in public health service.

The enzyme-linked immunosorbent assay (ELISA) and the neutralization test (NT) are often used to determine the level of seropositive population and to evaluate the immunogenicity of vaccines. ELISA provides information on the total pool of antiviral antibodies, while NT allows the antiviral protection level of a person to be estimated. It is assumed that the 1: 100 titer in ELISA and the 1: 10 titer in NT are protective. Obviously, the ratio of the total pool and virus neutralizing antibodies can vary as a result of natural immunization or vaccination. In this study, two methods were used to study the blood serum samples taken in a group of inhabitants of the Sverdlovsk region aged from 1 to 60 years. The samples were collected before immunization and 30 days after two immunizations with inactivated vaccines against tick-borne encephalitis of different manufacturers. Immunizations were performed either according to a standard scheme (30-day interval between immunizations), or according to an emergency scheme (14-day interval). It was shown that the data on the presence of antiviral antibodies in protective titers obtained by ELISA and NT were consistent in more than 85% of cases. The discrepancies between the data are due, in the first place, to the difference in the sensitivities of the two methods. The proportion of seropositive people according to NT data is always greater than that according to the results of ELISA. Nevertheless, among 174 children, about 5% of recipients after a double immunization were seropositive according to ELISA, but did not have neutralizing antibodies in protective titers.

The current national immunization calendar is intended for the pediatric population; the general concept of adult immunization is absent, which does not protect target groups under the conditions of the changing epidemic situation and the state of population immunity. Objective - to substantiate and design a national vaccine schedule for adults. Material and methods. The investigation was conducted using the data available in the Russian and foreign literature, the assessments of the epidemic situation among the adult population in the Russian Federation, and the authors’ own studies. Results. The draft national adult immunization calendar consisting of two sections was designed and substantiated. The first section includes information on immunization of different age groups; the second contains that on immunization of groups at epidemiological and social risks. Conclusions. The introduction of the national adult immunization calendar and improvements in the institutional framework of vaccination will achieve further reductions in morbidity and mortality rates in the country.

It has been reported that hepatitis B virus (HBV) is 10 times more infectious than hepatitis C virus (HCV) and 100 times more infectious than human immunodeficiency virus (HIV). Although there are two approved and very effective antivirals that quickly reduce the viral load (HBV DNA) and the risk of liver damage, vaccination prevention still represents the ideal intervention to reduce the spread of the disease and to protect public health. A literature review of the studies published in English on hepatitis B vaccination coverage of healthcare professionals in Greece during the 2006-2016 period was conducted. The literature review highlighted 12 studies. Healthcare professionals’ vaccine rate ranged between 55% and 88%. Doctors had the higher vaccination rate among healthcare professionals and registered nurses compared to nurses’ aides (p < 0.05). Higher educational level, knowledge of hepatitis B and a positive attitude toward vaccines (p < 0.05) revealed as the variables that affect positively healthcare professionals to be vaccinated. Mandatory vaccination of professionals within a health policy with regard to vaccination, as well as the implementation of information programs for them, are two important interventions that may increase vaccination coverage rates.
