Why a coronavirus vaccine won't be the panacea many hope for

Keep your mask on: Why a coronavirus vaccine won't be the panacea many hope for: The theory goes something like this: We will have a vaccine against the coronavirus; nearly everyone will want to be vaccinated; and, afterward, we can return to the way things were before COVID-19 became part of our lives. We can stop holding our breath, exhale, throw away our masks, and go back to living our lives.

But that’s not likely to happen anytime soon.
