[Novel vaccination concepts on the basis of modern insights into immunology]

Since their introduction more than 200 years ago, vaccines have prevented millions of deaths caused by infectious diseases. This progress was possible because these vaccines protect through antibodies, which are relatively easily stimulated. In the meantime, we understand that diseases such as AIDS, tuberculosis, malaria and hepatitis C cannot be tackled by these conventional approaches. Recent insights into immunology provide the basis for the development of custom-tailored vaccines to successfully combat these threatening infections. These new generation vaccines comprise components that modulate the mediators of immunity (B cells, T cells, antigen-presenting cells and cytokines) in such a way that the best possible immune response develops. Alternative application methods offer the possibility to further improve the immune response. Thus, hope remains that the remarkable increase in knowledge in the areas of immunology and infectious disease research will help to successfully control infectious diseases.
