I heard on the news tonight ... yes, a vaccine will come. But it would likely take a couple of years to be widely available. Even with the great progress and human trials that are being undertaken for about 27 potential vaccines around the world. Its efficacy would likely be in the 70-80% range. And there will be a rush on glass vials, and other manufacture and distribution issues - due to the immense amount of people who would need the vaccine. The expert (sorry, I forgot to write down his name) said that there would likely be a selection of covid vaccines that would become available. He also said that it is likely that all healthcare workers would be vaccinated first, as is usual. Then it would filter out to the general population.
