Climate Change and Vaccination Strategies: Analyzing Global Immunization Challenges

The purpose of the study was to analyse the quality of vaccination among the population and to evaluate strategies that contribute to reducing the prevalence of infectious diseases, the number of complications, and the severity of disease. The study also examined pathogens that pose a global threat to the population, which have high risks of outbreaks due to global changes in climatic conditions. The development of vaccines capable of preventing or eliminating an infectious disease, reducing the severity of the disease and the rate of hospitalisation has been studied. In addition, the issue of the causes of low vaccination coverage in Kyrgyzstan, Albania, Bulgaria, and Latvia has been investigated. It was found that diseases that have a geographical distribution in certain climatic zones have a risk of zone expansion due to global climate warming and changes in the habitat of the pathogen or its vectors to other regions. Global health systems are constantly working to create new vaccines and modernise old ones. Despite this, there are many reasons why vaccination coverage is not reaching the target values. These reasons include the availability of vaccines to the public, the level of knowledge of medical personnel and the trust of doctors in vaccination, the level of education of the population and the availability of information about the vaccine, commitment to vaccination in patients, and trust in international medical health systems. This means that low vaccination coverage can lead to a decrease in collective immunity, the occurrence of outbreaks of infectious diseases, and an increase in the burden on the health care system. Therefore, the main strategy for immunisation of the population is to eliminate the causes of low vaccination coverage, take measures to inform the population about vaccines, and increase people’s confidence in health systems.
