Why Scientists Didn't Make Ebola Vaccine?
Although the ebola virus has been found since 40 years ago, until now there is no vaccine to protect humans from this malignant disease. Moreover, the infection was spread in Africa today has killed more than 1000 people. WHO noted, this is the biggest in the history of Ebola infection.
Ebola infection is actually a rare disease. That's why pharmaceutical companies have not been too interested in investing to conduct vaccine research.
According Dr.Willian Schaffner of Vanderbilt University in Nashville, USA, as it includes rare, scientists are also difficult to study in this field. "Unlike the smallpox virus because they can find people who are exposed to this disease everywhere," he said.
Prior to the outbreak, since the virus was first discovered in 1976 there were only 2,000 cases. But when the disease is endemic, existing since the beginning of the year 1,323 people were infected in 3 countries and 729 of them died.
Emergency situation is occurring now in Africa has prompted more than 4,500 people signed a petition on Change.org that the food and drug regulatory agency USA (FDA) more quickly create ebola vaccine and a cure.
According Dr.Anthony Fauci, director of the National Institute of Allergy and Infectious Disease, actually since last March already done the research for ebola vaccine development.
"The vaccine has been tested in monkeys and in September will be entered in phase 1 clinical trials in humans. Estimated in mid-2015, although the vaccine has been available in limited quantities, for the health workers," he said.
Fauci explained, in the clinical trials of the respondents will not be given exposure to ebola virus, but they will be given a dose of the vaccine to see whether the antibody levels in accordance with the level of research monkeys. Scientists will also be able to determine the safety of this vaccine.
According to Professor of Viral and Molecular Biology University of Udayana, Bali, Gusti Ngurah Mahardika, ebola is not only ignored the scientists, but also bird flu, rabies, and HIV / AIDS.
"This disease occurs in developing countries that tend not to get the attention of researchers to Europe or the United States. It ignored. His research is not enough incentive to be done, "said Ngurah as quoted COMPASS (02.08.14).
Besides, he added, looking animal model for the human condition is difficult. "The disease in humans occurs with great, while the animal is not so severe," he said.
In addition, economic factors also affect. "The economy in developing countries is limited," he said again.
