When it will be it can also be used to easily create a cure if you can assemble viruses like legos it would be also incredibly easy to create inhibitors and anti bodies with the same technology.
This is also what we are doing atm basically playing a huge game of “Perfection” by trying to find anything that would fit one of the “holes” on the virus, our cells or those which open up during its assembly process like its viral protease.
I've heard a firsthand account from a guy who worked at Vector [0], that they had difficulty controlling viruses [1]. Accidental releases of weaponized bacteria also happened [2], but in that case they could prophylactically treat with antibiotics. That said, this was done using 1970's-1980's technology. I'm sure there's some more sophisticate bioweapons that are possible now. Maybe viruses are a more reasonable chassis.

virus is good for control in the case of accidents such as a biowar implement crashes somehow and spills virus, the environment will destroy it quickly, the cleanup is simple compared to a bacterial agent, eg anthrax in spore form lasts many years-->
This virus has shown the widespread economic impact and unpredictability that the uncontrolled spread of a virus can unleash on the world.
After this, I'm sure no superpower will want to take a chance releasing a weaponized pathogen: it might just come bite them back in the ass.
