I think the reason to continue the mask wearing and social distancing even after vaccination is because they aren't sure you can't still be infected and asymptomatic shedding the virus. I don't believe the vaccine guarantees you will not get the virus but helps guarantee it will not be as deadly if you do get it. This is a totally new virus. It's going to take a long time to establish herd immunity, even with the vaccine.

I guess there's one big plus to the social distancing mask wearing. There's been very few flu cases, and other viruses spreading. If we want to slow the variants down we have to get a grip on this virus. The more it spreads the more variants we're going to have. https://www.cbsnews.com/news/covid-19-vaccine-infectious.
