One thing I didn't see mentioned was a recent article that caught my attention - apparently, tobacco may be used as means of production for a potential vaccine [0].
Given that the linked article was published on April 1, I initially thought it to be satire. Upon further consideration, though, it not only seems to be genuine but it makes sense: tobacco is likely one of the best understood plants from a genetic standpoint, with a long history of successful genetic modification using both traditional and modern approaches. It's certainly one of the best understood that also has large-scale production capabilities, and I would imagine that the tobacco industry has more incentive than most to seek the positive PR that this could bring.
Finally, setting aside the greater political context, it seems to me that the FDA under the Trump administration is more flexible and risk-tolerant than any point in my lifetime (and perhaps in living memory). There are certainly many challenges that will have to be overcome before we get to the point that we're able to widely roll out an effective vaccine, but I strongly suspect that this flexibility will result in a speed of development and approval that will surprise many of us. Of course, that speed will come with associated risks, but that's just the nature of things.
I would not be surprised to see widespread voluntary human testing of promising vaccine candidates in the next six months - perhaps even sooner if a promising candidate ends up being derived from the past few years' work in creating a vaccine for SARS-CoV-1.
