More Feasible than EverVaccines can prevent many viral and bacterial infections. There has, however, never been a vaccine developed against a complex multi-stage parasite. Since malaria is caused by such an organism, developing a vaccine to prevent it is especially challenging. Despite the difficulties, scientists are proving that it is possible to create an effective malaria vaccine. A new generation of vaccines has been developed over the past 15 years. This new generation of vaccines is the result of a scientific revolution that has changed the scientific base for vaccine development. Advances in biotechnology--such as new cell culture techniques, DNA modification, and the mapping of the malaria genome--make a vaccine against malaria more feasible now than ever. Increasing recognition of the moral imperative to create vaccines against diseases that primarily affect people in developing countries, such as malaria, tuberculosis, and HIV/AIDS, also makes success in developing a malaria vaccine more likely. The development of a safe and effective malaria vaccine has at last become a global priority. |
