Retroviruses sometimes destroy the cells whose DNA they alter, as with HIV, and sometimes cause them to become cancerous, as with the viruses that cause certain leukemias. Retroviruses were discovered and/or engineered not so long ago. Biotechnologists want to harness the viruses’ capabilities to use as a tool.
The medical profession, especially in the US is still experimenting with retroviruses. This is a tricky experiment because viruses can end up infecting people. As one Neuroscientist pointed out, viruses are pretty crafty and can easily get around safeguards biotechnologists try to put up. Many in the medical profession think there is potential in using retroviruses to cure genetic diseases and are looking into retroviruses as therapeutics.
They also believe that the more they learn about retroviruses, the better they can treat people who have them. So by their own admission, the medical profession does not know much about retroviruses. As such the antiretroviral drug therapy is still an experiment which the US wants to test in South Africa.
Under the stewardship of former President Thabo Mbeki, Dr Tshabalala-Msimang refused to allow South Africans to be used as guinea-pigs. So why was Dr Tshabalala-Msimang crucified and lynched for using her professional discretion and prerogative? Those who continue to berate the late doctor are obviously doing the pharmaceutical companies’ dirty job. Unfortunately under the current buffoon’s administration the pharmaceutical companies will have their way.
