The World Health Organization (WHO) searches influenza virus circulation in community and in natural biocenosis, studies virus strains and their properties, develops diagnostic methods and preventive measures since 1940th worldwide because of epidemic actuality and high pandemic potential of the influenza virus. The Federal Influenza Center (including Federal Research Institute of Influenza, Saint-Petersburg, and the Center of Virus Ecology, D.I.Ivanovskiy Virology Institute, Honorary Academician N.F.GamaleyaFederal Research Center of Epidemiology and Microbiology, Federal Research Center for Epidemiology and Microbiology, Moscow) performs similar work in Russia in close cooperation with WHO within the framework of the International Programme of Influenza Monitoring. A(H1N1)pdm09 influenza virus dominated in the Northern Hemisphere in the 2015 β 2016 epidemic season. Morbidity growth was noted from the end of January, 2016, to the beginning of March, 2016. The peak morbidity at the 5th week of the year exceeded the epidemic threshold (132 cases per 10,000 of population) and morbidity in the 2014 β 2015 season significantly and approached to the peak morbidity of the 2009 β 2010 epidemic season. The epidemic growth in Russian Federation was provided by three influenza viruses: A(H1N1)pdm09, Π and A (H3N2). A(H1N1)pdm09 virus caused 18% of all acute respiratory diseases and accounted for 84% of circulating influenza viruses.Flu was diagnosed in patients of different age with maximal frequency in 3- to 6-year old children. Peak admission number was registered at 5 and 6 weeks (3,538 and 4,109 cases, respectively); this number exceeded the similar parameter of the 2009 β 2010 season. Patients of 15 to 64 years old were admitted more often including those with acute respiratory infection. Two hundred and thirty nine deaths were registered to the 5th of April, 2016, according to data from the Federal Influenza Center and the Center of Virus Ecology. The diagnosis of A(H1N1)pdm09 flu was confirmed in 97.9% of deaths. Molecular analysis of isolated strains of A(H1N1)pdm09 influenza virus revealed amino acid substitutions in receptor binding site and SA site of hemagglutinin and in genes coding intrinsic proteins PA, NP, M1, and NS1. Influenza virus strains resistive to anti-neuraminidase drugs were encountered in #< 1% in the Northern Hemisphere countries. No strains studied were sensitive to adamantine derivates.ΠΠΊΡΡΠ°Π»ΡΠ½ΠΎΡΡΡ. Π‘ 1947 Π³.

Peculiarities of the influenza viruses circulation and their properties during 2018-2019 epidemic season in Russia and countries of the Northern Hemisphere
Objective. To identify the drift variability of influenza viruses during the period of epidemic rise in the incidence of acute respiratory viral infections in the period 2018-2019. The biological and molecular-genetic properties of epidemic strains isolated in certain territories of the Russian Federation were studied and compared with data from the countries of the Northern Hemisphere. Materials and methods. A range of laboratory diagnostic methods has been applied, including immune fluorescence, RT-PCR, sequencing, methods for determining sensitivity to influenza drugs and receptor specificity. Results and discussion. The proportion of influenza viruses was as follows: A (H1N1) pdm09 - 53 %, A (H3N2) - 46 %, B - about 1 %. Cases of severe acute respiratory infections have most often been associated with influenza A(H1N1) pdm09 virus. According to antigenic properties, isolated strains corresponded to the properties of vaccine viruses (A/Michigan/45/2015 - by 99.6 % and A/Singapore INFIMH-16-0019/2016 - by 86 %). The heterogeneity of influenza A virus strains population was revealed as regards individual mutations in hemaglutinin. The influenza B virus population was equally represented by both evolutionary lines (B/Victoria and B/Yamagata-like). Receptor specificity was favorable for the course and outcome of the disease. Among 70 studied epidemic strains, no strains resistant to anti-neuraminidase drugs, oseltamivir and zanamivir, were detected. The article presents WHO recommendations on the composition of influenza vaccines for the countries of the Northern Hemisphere for 2019-2020, provides data on cases of human infection with avian influenza viruses A(H5N1), A(H5N6), A(H7N9) and A(H9N2)
Trivalent mRNA vaccine-candidate against seasonal flu with cross-specific humoral immune response
Seasonal influenza remains a serious global health problem, leading to high mortality rates among the elderly and individuals with comorbidities. Vaccination is generally accepted as the most effective strategy for influenza prevention. While current influenza vaccines are effective, they still have limitations, including narrow specificity for certain serological variants, which may result in a mismatch between vaccine antigens and circulating strains. Additionally, the rapid variability of the virus poses challenges in providing extended protection beyond a single season. Therefore, mRNA technology is particularly promising for influenza prevention, as it enables the rapid development of multivalent vaccines and allows for quick updates of their antigenic composition. mRNA vaccines have already proven successful in preventing COVID-19 by eliciting rapid cellular and humoral immune responses. In this study, we present the development of a trivalent mRNA vaccine candidate, evaluate its immunogenicity using the hemagglutination inhibition assay, ELISA, and assess its efficacy in animals. We demonstrate the higher immunogenicity of the mRNA vaccine candidate compared to the inactivated split influenza vaccine and its enhanced ability to generate a cross-specific humoral immune response. These findings highlight the potential mRNA technology in overcoming current limitations of influenza vaccines and hold promise for ensuring greater efficacy in preventing seasonal influenza outbreaks

The aim of this study was to monitor in-hospital influenza virus infection during 2015 β 2016 epidemic flu season. Methods. Influenza virus was searched in patients hospitalized to a clinical infectious diseases hospital with acute respiratory viral infection during 2015 β 2016 influenza seasonal growth period using real-time RT-PCR method. Influenza virus was isolated from nasal swabs and autopsy material using canine kidney cell line. Other laboratory methods used included complete blood count, blood chemistry, blood gas analysis, urinalysis, and chest X-ray examination. Results. We examined 1,491 patients (375 adults, 546 children, 570 pregnant women with early gestational age). The proportion of hospitalized patients with confirmed A / H1N1pdm09 influenza in January β February, 2016, was 91.3%. A / H3N2 influenza virus was diagnosed in 5.7%, influenza B virus was isolated in 1.2% of patients. Totally, influenza virus was detected in 35.2% of samples, of which 30.1% of samples were obtained from adults, 33.7% of samples were obtained from children, and 39.8% of samples were obtained from pregnant women. The prevalent patientβs age was 15 to 60 years (76.1%) in adults and 3 to 6 years in children. Moderate course of influenza with a high rate of hospital admission was seen more often and was similar to that of 2009 β 2010 epidemic season. Proportion of patients with flu complicated by pneumonia was higher than that in 2014 β 2015 epidemic season. Bilateral lung injury was diagnosed in 48.4% of patients. High mortality in ICU (46.4%) was due to delayed start of antiviral treatment and late admission to a hospital. Conclusion. In 2015 β 2016 epidemic flu season, higher morbidity, complications and poor outcomes were related to predominant infection of A β H1N1pdm09 influenza virus. Risk factors of complications and death were delayed care seeking, lack of modern antiviral medications and comorbidity.ΠΠΊΡΡΠ°Π»ΡΠ½ΠΎΡΡΡ.

Main Directions of Effective Influenza Prevention in Modern Conditions
This paper presents the risk analysis of influenza virus infection in different age groups based on the prevalence and mortality rates. The epidemiological characteristics of the influenza virus circulation during postpandemic period are given. Main aspects of specific and non-specific influenza prevention are discussed. The efficacy of the interferon-based medication Grippferon in the prevention of influenza and acute respiratory viral infections (ARVI) is justified

INFLUENZA INFLAMMATION BIOMARKERS FEATURES
Aim. Analysis of inflammation biomarkers using reverse transcription with real time PCRΒ (RT-PCR-RT) and multiplex immunofluorescent analysis xMAP with magnetic beads for theΒ influenza infection. Materials and methods. Analysis of nasopharyngeal swabs, lymphocytes andΒ blood sera of 10 patients with influenza and 10 donors was performed during the first 2 days of theΒ disease by means of RT-PCR-RT and xMAP using the kit Β«37-plexΒ» (BioRad). Results.The influenzaΒ virus A was revealed in 4 samples, the influenza virus B β in 6 swabs without mixed infectionsΒ with other respiratory viruses. Analysis of the interferons (IFN) showed IFNΞ± gene expressionΒ activation in patientsβ lymphocytes but both the detection rate and the concentrations ofΒ IFNΞ², IFNΞ³ and IFNΞ» RNA were similar for patients and healthy donors. Among 37 inflammationΒ biomarkers the concentrations of 7 proteins were enhanced including IFNΞ±2, cytokines ofΒ TNF family (APRIL and BAFF), their soluble receptors sTNF-R1 and sTNF-R2, protein osteopontinΒ and IL10. The concentrations of the complex of glycoprotein gp130 with the soluble receptorΒ IL6 gp130/sIL-6RΞ² and the matrix metalloprotease ΠΠΠ -1 were reduced in patientsβΒ sera. The polarization coefficient PI=[IL10]/[IFNΞ³]=0.53 for influenza samples suggested Th1Β immune response. Conclusion. At the early stage of the influenza infection IFNΞ± gene expressionΒ activation along with the induction of TNF family cytokines (APRIL and BAFF), their receptorsΒ (sTNF-R1 and sTNF-R2) and osteopontin as well as the inhibition of the complex gp130/sIL-6RΞ²Β and metalloprotease ΠΠΠ -1 were shown. Th1 immune response regulated by IL10 resulted inΒ the recovery of the patients without complications
