Since there are so many variables here (density, level of interaction, mask compliance, "superspreaders", transit type, etc.), and many of them could correlate with whether or not people are interested in getting vaccinated, I would dig much deeper before concluding anything.
Point taken. I think an appropriate thing to say is that this is suggestive evidence that vaccines work, though this graph in and of itself does not establish the causal link.
I mean, I suppose, but if you wanted to demonstrate that with a graph, would the graph be number of cases in vaccinated people vs. number of cases in unvaccinated people? If the goal is to demonstrate that vaccines work, there are much better graphs than this one.
