Why would you need to shut the country down with a vaccine available? Your biggest problem is the antivax refuseniks and there are ways to deal with that. It shouldn't just be a case of sticking needles into people and saying job done, it's adding the vaccine to the already-deployed methods that will lick it.
You are assuming here that an effective vaccine will be available next year. This is by no means guaranteed. The vaccines under development now may not work or they all may have serious side effects. In fact, there is currently no evidence that any of them will actually prevent a person from getting the virus.
