The production of recombinant coronaviruses to assess pandemic potential was carried out in several laboratories, all funded by the NIH. Recently Dr. Anthony Fauci told Congress that the NIH did not fund GoF coronavirus research. The press has suggested that he lied, but the truth is that his definition of GoF research is that it only involves passaged of organisms in animals. This interpretation is not correct but being wrong does not mean you are lying.
I want readers to understand that the goals of GoF research are
laudable, and only a small subset has the potential to harm humans.
Consequently these experiments are highly regulated and carried out
under high levels of biological containment. GoF is not a dirty word.
