I have worked as an operator in a chemical plant for 30 yrs and I have been thinking the same thing. Tanks and piping (hoses if you're in a hurry) are not that hard. Any specialty equipment (centrifuges, specialized lab equipment, etc) is generally off the shelf. Quality control would probably be the most ticklish aspect, but that could be expedited and dealt with. No doubt I'm glossing over a number of sticking points. But this is an emergency, not just for covid, but for the millions of other people this drug might save from early deaths. If the right people will get off their butts and start throwing a some money at this problem, I do not doubt for one instant that development of large productive capacity couldn't be sped up by at least an order of magnitude. The world needs leronlimab. What the hell are our so-called leaders waiting for? This is the moment when we need dynamic, insightful leadership in the Oval Office. Unfortunately...(cue crickets)
