To be honest, there is probably a power law graph in play here when it comes to how many people are infective and infect others. If we can vaccinate / prevent spread in the demographics that are prone to mixing a lot / threaten spread, we can quickly curb it and then focus on people who are less likely to contract it / spread it around.
It feels like some of the demographics most likely to spread have overlap with groups unlikely to accept vaccinations.

This is certainly the case. I don't have a link, but one study suggested 80% of cases were from "super-spreading" events, with one person infecting many others.
