I don't have much faith in the development of an effective vaccine any time soon for this particular virus. That hasn't went well for SARS 1 or the virus that causes MERS.
Another complicating factor for the response to this virus that I haven't seen mentioned here (I may have missed it though) is the poor sensitivity of the current testing. That combined with the great number of asymptomatic or minimally symptomatic cases, the incubation period, the significant severity in some patients, and the high infectivity make the response to this virus a challenge even under the best circumstances.
Having a skilled leader and business man at the controls who does not accept the bureaucratic staus quo or some of the excuses from other federal and state officials, instead having the typical politician leading the country, may in the end be responsible for saving more lives than any other single factor.
