Tropical Medicine and Immunization Vaccine

A vaccine is a suspension of the whole or fractionated bacteria or viruses that are rendered non-pathogenic. Vaccination has been extremely effective in preventing various serious infections that were once fatal and now have been eliminated. However, these infections still occur in parts of the under-developed and developing nations. Vaccines are frequently unavailable in developing countries. Each year, millions of people die from drug-treatable vaccine-preventable diseases. Furthermore, successful vaccines have yet to be developed for major global diseases such as tuberculosis. In addition, technologies that are used to develop and manufacture vaccines are often outdated and are not easily adaptable for rapidly responding to disease outbreaks, such as influenza.
