Lyme disease (LD) remains an important public health problem, especially in Russia, where the incidence is consistently high. To date, there is still no available vaccine against LD, and prevention involves non-specific measures. Aim: to review the literature and summarise data on progress, approaches and strategies for LD vaccine development. Conclusions. The first LD vaccines were developed in the 1990s. An OspA-based vaccine (LYMErix) was commercially available in the early 2000s but not widely distributed. An important milestone in the development of LD vaccines was the shift from the development of monovalent vaccines based on a single type of outer surface protein to the development of multivalent combinations that provide protection against different Borrelia genospecies. A multivalent OspA-based vaccine (VLA15) is in phase III clinical trials and is likely to be the next LD vaccine available on the market. New genetic strategies for vaccine development, identification of new immunogens, and development of vaccines targeting different parts of the LD transmission cycle are of broad interest for further development of LD vaccines.","PeriodicalId":11736,"journal":{"name":"Epidemiology and Vaccinal Prevention","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141017133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The high intensity of the therapeutic and diagnostic process in medical organizations is accompanied by an increase in the manipulation load on patients and, accordingly, an increase in the risk of post-injection infectious complications. In the Russian Federation, in the structure of infections associated with medical care, post-injection complications in the last ten years before the pandemic of a new coronavirus infection occupied 7.0–11.0% [1]. The question of the impact on the prevalence of post-injection complications of medical care conditions that changed during the COVID-19 pandemic remains open for discussion and study. The purpose of this study is to give an epidemiological characterization of post–injection infectious complications in medical organizations, to determine their place in the structure of patient health losses in order to improve the monitoring system for infections associated with medical care. Materials and methods. The forms of statistical observation No. 1, 2 «Information on infectious and parasitic morbidity», No. 30 «Information on medical organizations» for the period 1994–2022, 101 forms of epidemiological investigation of cases of post-injection complications for the period 2015–2022 are analyzed. Epidemiological and statistical research methods were used in the work. Conclusions. During the study period, the prevalence of post-injection complications in outpatient polyclinic organizations of the Khanty–Mansiysk autonomous okrug – Ugra was 0.10 per 100 thousand visits and 3.85 per 100 thousand treated in hospital. The risk groups for post–injection complications were persons of older age groups, and the place of risk was procedural, vaccination rooms, and neurological departments. Abscesses prevailed in the structure of post-injection complications (85.4%), with the most frequent localization of post-injection complications in the gluteal region (47.7%). During laboratory examination of the material, gram-positive microorganisms were isolated from the focus of infection in 72.9% of cases, the largest proportion of which was Staphylococcus aureus (74.3%), including MRSA. In 80.5% of cases of post-injection complications, surgical intervention was required, including 77.8% in a hospital setting. The prerequisites for the occurrence of post-injection complications were excessive manipulation load, prescribing more than 5 drugs to patients and non-compliance with the instructions for injections in 4.8%. The complexity of monitoring post-injection complications is due to the lack of a standard definition of the case in most nosological forms, deliberate concealment of cases of infectious complications and imperfection of laboratory diagnostics.","PeriodicalId":11736,"journal":{"name":"Epidemiology and Vaccinal Prevention","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141016181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Growing distrust of vaccines around the world, a decrease in vaccination rates have led to an increase in the incidence of measles and a rise in the vulnerability of people with immunodeficiency status. The aim. To study the efficacy and safety of measles vaccination in children with oncohematological diseases. Materials & methods. The study involved 107 children: 74 of them with a history of acute lymphoblastic leukemia and 33 with solid tumors. All children had a history of receiving standardized polychemotherapy. In all the subjects, the vaccination history was studied, the titers of specific antibodies to measles were determined. Children with non-protective levels of antibodies (53 children) were subsequently vaccinated against measles. Results and discussions. Of the 107 children examined, before cancer, 99 (92.5%) were vaccinated against measles, of which 68 (68.7%) patients were only vaccinated, and 31 (31.3%) had vaccination and revaccination. Protective titers of antibodies against measles were preserved in 51 people (51.5%), and 48 (48.5%) were seronegative.

Respiratory infections are an urgent problem for organized groups, including military ones, since the transmission of pathogens by airborne droplets and household contact routes, physical and psychological stress on adaptive mechanisms contribute to the development of the epidemic process. There is no doubt that vaccination makes a significant contribution to the prevention of respiratory infections, but the contingent remains vulnerable to other pathogens against which there are no vaccines. Therefore, the search for new methods of non-specific prevention is necessary in maintaining the health of persons permanently residing in collectives. Aim. Evaluation of the possibility of using the topical form of the recombinant interferon α-2b drug for the prevention of acute respiratory viral infections in organized groups. Materials and methods. The work was carried out according to the methodology of a multicenter (3 Centers) double-blind controlled trial involving 3,235 people aged 18 to 22 years, who were divided into three groups: 1 gy. - received a recombinant interferon α-2b (Grippferon) drug 3 drops in each nasal passage 2 times a day in for two weeks; 2 g. - saline solution intranasally according to the same scheme; 3 g. - the volunteers did not receive anything. The frequency of respiratory infections was studied. Results and discussion. Medical monitoring of the study participants, which was carried out for 2 months, showed that in the groups from the Center 1, the incidence of acute respiratory diseases for 2 months in the main group (gr. 1) was 2.3 times lower than in the control (gr. 2) and the comparison group (gr. 3). In the Center 2 The data corresponded to the dynamics of Center 1: the incidence values were 2.4-2.5 times lower in Group 1. In Center 3, the values were 2.0-2.1, respectively. The epidemic effect of intranasal administration of the topical form of the drug recombinant interferon α-2b is due to its effect on the factors of mucosal immunity, which contributes to non-specific protection and increased body resistance against respiratory infections. Conclusions. The presented advantages of the recombinant interferon α-2b drug make it possible to draw attention to the clinical feasibility of its use for preventive purposes in organized groups, including military ones, from the position of high epidemiological effectiveness, both pre-exposure and post-exposure prevention of acute respiratory viral infections.","PeriodicalId":11736,"journal":{"name":"Epidemiology and Vaccinal Prevention","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141018763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After smallpox eradication, in conditions of population immunity to orthopoxviruses absence, Monkeypox virus became most significant orthopoxvirus, pathogenic for humans. Therefore the generalization of data on the areas of infection outbreaks, human diseases and methods of prevention and treatment of monkey pox is important task. Aim. To characterize the problem of monkeypox in the world based on an analysis of foreign scientific publications over the past 20 years. Materials and methods. The work used publications presented in the main international medical information databases PubMed, Web of Science, Embase, etc. To analyze the publications, the analytical epidemiological method was used. Results and discussion. Monkeypox virus, obtained and identified in 1958, by genetic and phenotypic differences divides on two clades: West-African with lethality 3.6% and Central-African (Congo Basin) with lethality 10%. Monkeypox virus transmission to men happens in two ways, either from animal-to-human or human-to-human. Monkey pox is endemic only on African continent, but In 2003 year the first outbreak, numbering 47 confirmed cases, was occurred in non-endemic country – USA and the largest monkeypox outbreak began in Nigeria in September 2017 year and continue to the present. Comparison of the genome sequences of strains, isolated from patients in non-endemic countries, showed, that it genetically close to West-african strains, belong to II clades and were descended from a common ancestor. Many cases of disease in humans in the current outbreak have been traced to sexual transmission especially among men, who identify ourselves as gay or bisexual. The basis method for identification of agent in present time is PCR-RT targeting on the tumor necrosis factor (TNF) receptor gene. Usually monkeypox of human is mild, self-limiting disease. The symptoms of monkeypox are varied and non-specific. One of the most frequently observed clinical symptoms is lymphadenopathy. Most patients recover during some weeks. However, specific antiviral treatment – tecovirimat (S-246) and brincidofovir (CMX-001) – may be used for seriously ill or immunocompromised individuals. For prophylactic disease in present time are use vaccines JYNNEOSTM, ACAM2000R and Aventis Pasteur (APSV). Conclusion. General vaccination against monkeypox don't develop accordingly to modern recommendations WHO. Ring vaccination is recommended to conduct for suppression of spread virus in nidus of infection among population. Timely international coordination is needed to prevent the global spread of a disease with epidemic potential.","PeriodicalId":11736,"journal":{"name":"Epidemiology and Vaccinal Prevention","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141018865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The evolutionary association of Vibrio cholerae with chitin provided resistance to stress and protection from predators. The most important mechanism that provided V. cholerae with the effectiveness of association with chitin is biofilm formation. The ability to form a biofilm in V. cholerae depends on the presence of a factor, toxin-corrected adhesion pili (TCP), which are synthesized by the tcp A-F genes. One of the key methods for studying biofilms is microscopy. It allows one to visualize the structural elements and study various parameters of biofilms and the effects of various factors on them. Aim. To determine the epidemiological significance of the biofilm-forming ability of toxigenic strains by their morphological characteristics on chitin-containing substrates. Study of structural differences in biofilms of Vibrio cholerae tcpA+– and tcpA– strains on chitin-containing substrates. Results. It has been shown that Vibrio cholerae tcpA+– and tcpA– strains are able to form biofilms on the surface of chitin-containing substrates. The intensity of biofilm formation is more pronounced in tcpA+ strains, because V. cholerae ctxA+ tcpA+ cells in the biofilm are predominantly singly located and the surface of the chitinous exoskeleton with which they are in contact is intact, V. cholerae ctxA– tcpA– cells form chains in the biofilm, which indicates division processes, and scattered chitin of the endocuticle indicates activity of metabolic processes. Conclusion. The strains of V. cholerae used in the work, regardless of the presence or absence of the ctx and tcp genes, form bioplecs on a chitin substrate. The indicator of biofilm formation in terms of the thickness of the biofilm matrix is higher in V. cholerae ctxA+ tcpA+ , in terms of the degree of degradation of the chitin substrate it is higher in V. cholerae ctxA– tcpA– .","PeriodicalId":11736,"journal":{"name":"Epidemiology and Vaccinal Prevention","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140091633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
