@Ahuka Just been listening to TWiV where they were talking about the potential vaccine(s). They pointed out (as have others) that a vaccine may give 'sterilising immunity' meaning you can't catch COVID-19 again, or it'll give disease prevention meaning you can catch it but it will be very mild. Trouble is there's a likelihood that people with a mild case will be just as dangerous to others as people with the full disease since they'll be shedding virus. Masks will then continue to be needed!
