It is not obvious to me this is the case. All available data suggest that between the vaccine and natural immunity, we would have reached herd immunity if such a thing were possible. But we have not, indicating the primary benefit of the vaccine is, and will likely always be, some personal protection. Put differently, we will all get COVID eventually, and would have even if everyone was vaccinated, and the question is just one of the severity of individual cases.
