Tuberculosis vaccines were created 100 years ago and they are not up to the demand - the head of WHO

The World Health Organization intends to create a Council for the accelerated development of vaccines against tuberculosis. This was announced at the World Economic Forum in Davos by WHO Director-General Tedros Adhanom Ghebreyesus, the UN press service reports. The Council will help to overcome barriers to the development of new TB vaccines, as well as their licensing and early use.  "One of the most important lessons of the COVID-19 pandemic is that innovative health interventions are only taken quickly if they are given political priority and adequate funding," Ghebreyesus said. While countries have made bold commitments to end TB by 2030 as part of the Sustainable Development Goals, the epidemic shows no signs of slowing down. In 2021, approximately 10.6 million people fell ill with tuberculosis and 1.6 million died. Currently, the only licensed TB vaccine in the world is BCG, developed more than a hundred years ago. It is moderately effective in preventing severe disease in infants and young children, but fails to provide adequate protection for adolescents and adults, who account for about 90 per cent of TB transmission worldwide. A recent WHO study estimates that if a new vaccine is effective in 50 percent of cases, up to 76 million new TB cases, 8.5 million deaths, 42 million antibiotic treatments, and $6.5 billion in costs could be prevented within 25 years. If a vaccine is developed with 75 percent efficacy, 110 million new TB infections and 12.3 million deaths could be prevented in the same time.

What vaccinations in Uzbekistan can be obtained for free – list

The republic has approved a national calendar of preventive vaccinations, which a person should receive from birth to 16 years. In addition, there is a calendar of preventive vaccinations for epidemic indications. The Committee for Sanitary and Epidemiological Welfare and Public Health reported that 164 cases of measles have been detected in Uzbekistan since the beginning of 2023. Experts explained that the disease was diagnosed mainly in citizens who were in contact with measles patients who came from abroad. "Currently, the epidemiological situation of measles in Uzbekistan is under control. Persons who have been in contact with measles patients are covered by preventive vaccination," the Committee said. According to the WHO, in 2023, the epidemiological situation for this disease in the world worsened due to the refusal to vaccinate.

There it is designated as KPK - a trivalent live vaccine against measles, mumps and rubella. The vaccine is given twice - at the age of 12 months and six years. Since 2019, Uzbekistan has been vaccinating girls against the human papillomavirus (VPCH) from the age of 9. In this regard, the national calendar was replenished with another mandatory vaccination at the expense of the state. In addition, the republic has developed a calendar of preventive vaccinations for epidemic indications. In this case, vaccinations are subject to, among other things: - people engaged in catching and keeping stray animals; - service sewerage facilities; -working in the fields of medicine, education, food industry; - children of preschool age and persons over 60 years of age with chronic somatic diseases, often suffering from acute respiratory infections; - children and adults in whose families there is a patient with chronic hepatitis B; -children from orphanages and boarding schools; - children and adults who regularly receive blood and its preparations, as well as those on hemodialysis and oncohematological patients.
