The improvement of the people’s quality of life is the main purpose of the world health organisations and institutions. Biomedical scientists along with doctors and authorities work to make the nations healthier. Many products of the biotechnological research contribute to the improvement of the people’s health and increase of the life expectancy. Vaccines as the products of biotechnology are widely used today in medicine to predict a lot of severe diseases along with eliminating the diseases’ spread round the world. The specifics of vaccines’ effects are based on the increase of the people’s immunity. From this point, vaccines can guarantee the prolonged effect and protect from infections and diseases’ development completely. Vaccines are important for the development of the healthy society in developed and developing countries because they help people predict and overcome severe and deadly diseases. Vaccines are specific mixtures which contain weakened or killed bacteria or viruses, or parts of viruses depending on the type of a vaccine. Vaccines are developed to imitate the infection and stimulate the organism to produce specific antibodies which can fight this or that virus. When the organism overcomes the virus from the vaccine, the immune system develops the immunity against this type of viruses (Rappuoli et al. 2011). As a result, the person’s body can successfully fight the further infections associated with the definite disease. In spite of the fact the principle of a vaccine’s work is rather simple, there are a lot of debates on the effectiveness and safety of vaccines. That is why, it is significant to pay attention to the role, importance, and potentials of using vaccines in medicine. Focusing on the impact of vaccines on the individual health, it is necessary to pay attention to the fact that vaccines are more effective than any other types of medical prevention and treatment of diseases. The human organism develops his own immune system to protect the body from infections. That is why, vaccines are important to help people overcome the severe diseases without being infected. Moreover, the stimulation of the immunity contributes to the whole improvement of the people’s health. The developed immunisation schedule provides people with the opportunity to protect people from the majority of infectious diseases, contributing also to decreasing the costs associated with treatment (Schuchat 2011). The role of vaccination in coping with viruses and bacteria from which suffered the previous generations cannot be overestimated. Nevertheless, it is also important to concentrate on the larger scope of vaccines’ effects on the global population’s health. Vaccination is the necessary measure to avoid a lot of infections spread in developing countries. From this perspective, vaccination is effective to reduce the rate of severe and incurable diseases not only in developed countries but also round the globe. The focus on vaccination helped reduce the rates of infectious diseases in Asia, Africa, and Latin America. Some severe diseases which caused thousands of deaths decades ago can be discussed as preventive today because of the possibilities provided by the development of b
