While it's a potentially good sign, folks really need to understand some key points:
1.) This is likely not going to be a vaccine. In the history of Coronavirus vaccine research, there is no working vaccine for any derivative of Coronavirus.
2.) This is likely going to be a step forward in the treatment protocol but won't be commercially available for at least 6 months, even with all the red tape cut. The physical act of production takes a long time.
3.) Whatever happens with an eventual treatment first, it will initially go to hospitals for treating the most dire cases.
