According to Oxford Dictionaries a vaccine is a substance used to stimulate the production of antibodies and provide immunity against one or several diseases, prepared from the causative agent of a disease, its products, or a synthetic substitute, treated to act as an antigen without inducing the disease. This program will look at the science behind the development of vaccines used to eradicate diseases and epidemics. The ability for vaccines to control and eliminate life-threatening infectious diseases will be discussed along with innovations that make vaccinations safer than ever. Since the beginning of time, populations have struggled to eliminate potentially deadly diseases that claimed the lives of millions. From typhoid and yellow fever to polio and smallpox, the eradication of highly contagious disease has been a focus of scientists and medical professionals. A vaccination works to develop immunity by imitating an infection. The immune system then develops the same response as it would to a real infection, introducing the antigens needed to fight off the virus and bacteria that cause deadly diseases. New vaccines are being developed thanks to advances in biotechnology and genetic engineering. Vaccines for the flu are in ongoing. We already have vaccines that prevent influenza, but there is a catch. Specialists have to keep creating vaccines that target specific flu strains each flu season. However researchers are in constant development to create a “universal vaccine” that could target all influenza viruses effectively. Vaccines treating high cholesterol are actively being tested, as well as those to fight cancer, cholera, and RSV (respiratory syncytial virus). The scientific and medical professionals in these positions hold the potential to control the spread of disease that is essential to our long term survival.
