Thanks to routine immunization, we managed to forget about the many incredibly contagious and dangerous diseases. Nevertheless, it’s too early to relax: if group immunity decreases due to refusal of vaccination, terrible epidemics can return, and these are not just words. In 2018, the media anxiously reported frequent cases of measles, or the “childhood plague,” as it is called. In this article of the “Vaccination” special project, we will tell you why measles is dangerous, how to deal with it, and why it is still not defeated.
The invention of vaccines has radically changed the life of mankind. Many diseases that claimed thousands, or even millions of lives annually, are now almost never encountered. In this special project, we not only talk about the history of vaccines, the general principles of their development and the role of vaccine prevention in modern healthcare (the first three articles are devoted to this), but we also talk in detail about each vaccine included in the National vaccination calendar, as well as flu vaccines and human papillomavirus. You will learn about what each of the causative agents of the disease is, what vaccine options exist and how they differ, and we will touch upon the topic of vaccine-related complications and the effectiveness of vaccines.

The structure of the human respiratory system The human respiratory system consists of tissues and organs providing pulmonary ventilation and pulmonary respiration. In the structure of the system, it is possible to distinguish the main elements – the airways and lungs, as well as auxiliary – elements of the musculoskeletal system. The airways include: nose, nasal cavity, nasopharynx, trachea, larynx, bronchi and bronchioles. The lungs consist of alveolar sacs, bronchioles, as well as arteries, capillaries, veins of the pulmonary circulation. Elements of the musculoskeletal system associated with breathing include ribs, intercostal muscles, the diaphragm, and auxiliary respiratory muscles. Numerous studies carried out in various countries have shown a significant increase in respiratory diseases over the past 10 years.
