This is exactly what USAMRIID is supposed to be doing... their work is classified and should be. Likely they are trying to develop effective vaccines in case our enemies create a weapon like this to use against us. The only issue is Fauci is as usual looking at the perception of public awareness that vaccines can’t protect you and may lead to worse outcomes.
Read “The Hot Zone”, I might peruse it again. Read it while studying veterinary biology quite a few years back (1990’s).
Or you develop a bioweapon because you are a one of the sociopathic elitists who wants to knock off 99% of the population. Then you develop a vaccine so that you, your fellow elites, and the 50 million or so people you deem to allow to live so that they can be your slaves survive.
