They have been at it a while.

Current events reminded me of and interview article I wrote in 1998. Serbian AIDs doctor warning about the AIDS Vaccines and how it jump.
“Q: You also suggest that the Vaccine development may lead to a “super bug” of HIV which spreads though populations, undetectable and via Bacterial and virus infectious in a manner that is not necessarily though sexual contact or other traditional means of HIV infections. i.e. something like the common cold. Have you demonstrated this in your studies?
A: One of the widely applied approaches in the AIDS vaccine development is incorporation of the HIV gene coding for gp120/160 into some very ineffective viruses and bacteria (viral and bacterial vectors) or use an attenuated HIV. We have demonstrated that this HIV gene is inherently very recombinogenic (able to make combination with other human and non-human genes). As the consequences of this property, as well as property described in the item 1 it is possible that: (1) genetically engineered pathogen (virus or bacteria) carrying HIV-1 gene coding for gp120/160 or the attenuated HIV which is used as the AIDS vaccine could affect human immune system in similar manner as HIV and could accidentally spread like the common cold, and (2) such vectors carrying this gene could transfer it to other coinfecting pathogens (bacteria and viruses) in this way transferring to them some pathogenic properties of HIV. Such transfer possibly occurred in mycoplasma fermentas coinfected with HIV, and we have today new chimeric pathogen which is extremely ineffective and which attack immune system in similar way as HIV producing Gulf War syndrome (see work of Prof. Garth Nicolson). Because of possible release of such pathogens through vaccination, as well as accidentally from labs, we are calling for serious control of such experiments.”

The Good doctor documented his efforts in various letters/emails to the WHO and NIH, including Dr. Fauci.
