Incorrect. It's highly likely that a vaccine of some variety will be introduces prior to year end. State health departments are already planning and prioritizing regions and populations that will be targeted for the initial doses that are produced.
Testing needs focus as well, but the focus need to be on rapid response testing. The testing that requires a day, or multiple days, for results is relatively ineffectual in practice.
Yeah as far as being functional for being able to head out, see people etc. if you're able to quarantine while waiting for the results.
