How quickly will a vaccine be here?  Already, medical ethics have been pushed to the limit to deliver one.  COVID-19 was first discovered a few months ago.  Last week, three separate research teams announced they had developed vaccines.  Yesterday, one of them (with FDA approval) injected its vaccine into a live person, without waiting for animal testing.  Now, though, they have to monitor the test subject for fourteen months to make sure the vaccine is safe.  This is the part of the testing that can't be rushed: the plan is to inoculate the entire human population, so if the vaccine itself turned out to be lethal for some reason, it could potentially kill all humans, which is a lot worse than 90 million deaths.  Assuming the vaccine is safe and effective, it will still take several months to produce enough to inoculate the global population.  For this reason, the Imperial College team estimated it will be about 18 months until the vaccine is available.
