This is excellent news.
My only concern in the meantime is that of the common sense of Joe Public. With the news of the vaccine and as it gets rolled out, I've a bad feeling that a lot of people will begin to disregard all the rules while they're still in place, because "it's alright, there's a vaccine now!" Do correct me if I'm wrong, but I'm sure I heard that it's a process of two injections a month apart, which only begins to take effect after the second month? Meanwhile if enough people start to flout the guidance and laws before the vaccine has time to have its effect, it could lead to more and more deaths.
I hope I'm wrong though!
