According to the latest news, we should probably plan for a time frame a lot longer than what the President suggested in his speech recently. It is projected that it will be 14 months (starting in April) for this first study of 45 people to be completed. This is a very small, initial study. Following the results of that study, there will need to be larger, multiple, additional studies of more people's reactions and the effectiveness of the proposed vaccine. The possibility of it taking close to two years to develop, test and to modify dosages before a safe and effective vaccine is available for COVID-19, may even be a bit optimistic. To look at the bright side, throughout history, many vaccines for much deadlier diseases took decades of trial and error, before a safe and effective vaccine was even available. With scientists' efforts to develop the vaccine for COVID-19 now going world-wide, and also in this age of super-computers, all of those time frames have been greatly shortened.
