While presenting at an International Consultative Workshop on “Gain-of-Function Research on Highly Pathogenic Avian Influenza H5N1 Viruses”, Dr Anthony Fauci defines Gain of Function (GOF) research by specifically stating:

[w]hat historically investigators have done is to actually create gain-of-function by making mutations, passage adoption, or other genetic techniques, such as reverse genetics.

These “reverse genetics” techniques were used in the Wuhan lab for coronavirus research, using grant funds from the NIH.

This 2012 definition of GOF is contrary to Dr Fauci’s congressional testimony in May 11, 2021 [1].
