Relevance. In recent years, there has been an increase in the incidence of a number of vaccine-preventable diseases. The health of military personnel directly affects the combat effectiveness of the army. Aim. Preserving the health of the military and ensuring the sanitary and epidemiological well-being of the troops is one of the most important tasks. Result. Approaches to vaccination of persons subject to conscription for military service and a list of infections against which they should be vaccinated (influenza, meningococcal and pneumococcal infections, chickenpox, COVID-19) are presented. Vaccines, schedule and features of vaccine administration are described. A list of the main regulatory documents for vaccination is provided. Conclusion. Vaccine prevention of persons subject to conscription for military service is an important strategic task, the implementation of which depends on coordinated work between military and civilian healthcare. Vaccination coverage of persons subject to conscription for military service must reach 100%.

Seroepidemiology is a potentially powerful tool for predicting and monitoring the effectiveness of specific prevention program using studies of antibody prevalence. The availability of a certified collection of blood serum (serum bank) allows to carry out a reliable assessment of population immunity to vaccine-preventable diseases; to determine the degree of epidemiological risk of the infection spread in various areas of the country; to implement short-term and long-term forecasting of changes in the situation on topical infections; to substantiate preventive measures in the system of biosafety for defined population groups and decreed contingents; to provide information necessary for making the optimal management decisions.

The article presents incidence rates of major vaccine-preventable diseases in the world and the Russian Federation and cites mitigation measures that, in the end, must lead to the elimination of the diseases.

Nigeria, with its low routine immunization coverage and wild poliovirus reservoir, significantly contributes to overall regional burden of vaccine-preventable diseases. Since introduction of the EPI in 1974 (which later became the National Program of Immunization), Nigeria's immunization program suffered from declining coverage. The poor quality of immunization affects service utilization, even where they are provided for free, just as immunization services are. The quality assessment will provide both notion of degree of satisfaction of clients with services and framework for revision of program priorities, strategies and components Purpose of the study is to evaluate quality of immunization services provided to children in primary health centers in Oron, Akwa Ibom State, Nigeria. The study targets to identify strengths and weaknesses of immunization services, to evaluate level of compliance with national and international standards of immunization and to develop corresponding recommendations. The study seeks to contribute to body of knowledge about quality of children immunization services in Nigeria, particularly in context of primary health centers. The study may help to improve delivery of immunization services in the region and to ensure that more children will be vaccinated and protected against vaccine-preventable diseases. The cross-sectional descriptive study of quality of immunization services in primary health centers was carried on in Akwa Ibom State, Nigeria. The variables as indicators such as physical environment, resource availability, client satisfaction etc. were utilized and included into questionnaire. The study covered 402 caregivers and 152 medical workers in 12 primary health centers. The client questionnaire, facility staff questionnaire, facility checklist, personal observation,focus group discussion guide and client flow chart were applied. The results demonstrated that quality of immunization services was poor. The caregivers were dissatisfied both with reception by providers and too long waiting time. The attitude of health care providers was also mentioned as cause of dissatisfaction. This study demonstrated that community health extension workers constituted majority (39.4%) of immunization service providers. Out of 152 health care providers that participated in the study, 92 (60.9%) had attended in-service training on immunization within previous two years. The comparison of staff categories with attendance at in-service training established statistically significant difference (p=0.0072), suggesting that whether one attended in-service training or not depended on category of staff one belongs to. Of all staff, 112 workers (73.3%) knew proper vaccine storage temperature while 40 (26.7%) did not. The health care providers who do not know proper vaccine storage temperature may administer vaccines with compromised potency. Most of health care providers (149 or 98.0%) were aware that clients have particular rights that in overall is referred as client rights. Only by knowing rights of clients providers would be expected to respect these rights. The client right with which most of providers were agreed was right to information (105 or 70.2%). While right with which most providers were disagree (52 or 34.0%)) was right to choice of where and when access immunization services. The study conducted thorough quality assessment of children imunization services in primary health centers in Oron, Akwa Ibom State, Nigeria. The results revealed both strengths and weaknesses in delivery of immunization services to children in the region. While there were areas of average performance due to experienced and trained health care workers, there were also areas of concern with inadequate cold chain storage and insufficient record-keeping practices. The study recommends to improve quality of immunization services in the region, including strengthening cold chain system, ensuring adequate record-keeping practices and implementing regular training and supervision of medical workers. These measures are crucial to ensure that more children are vaccinated and protected against vaccine-preventable diseases. The results of the study contribute to body of knowledge on quality of children immunization services in Nigeria and emphasize importance to continue efforts improving delivery of immunization services to children. There is hope that proposed recommendations will become a basis for policy decisions making and ultimately will result in better health outcomes for children in Oron, Akwa Ibom State and beyond.

The article presents an overview of modern approaches to vaccine prevention in multiple sclerosis (MS). Compared with the general population, patients with MS have been shown to have an increased risk of morbidity, a tendency to have a more severe course, and a greater mortality from vaccine-preventable infections. At the same time, in Russia, until recently, traditionally adhered to a conservative tactic of limiting vaccination in patients with autoimmune diseases, including MS. The use of various disease-modifying therapies (DMT) may also affect the susceptibility to infections and the severity of their course. Screening for latent infections, determination of immune status, collection of history of past infections and development of a vaccination plan based on these data are an important part of the preparation before the appointment of DMT to control the occurrence or reactivation of infections. The use of inactivated, subunit, conjugate, and toxoid-based vaccines are preferable for MS patients. When developing a vaccination plan, avoid live-attenuated vaccines whenever possible. There are no restrictions on vaccination during first line DMT intake. In case of vaccination in MS patients while using immunosuppressants, including drugs for immune reconstitution therapy, an individual risk assessment and timing are required. The available data on the awareness of patients about vaccine prophylaxis are significantly limited and require mass information events.
