Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that vaccination contributes to herd immunity by reducing disease transmission within a population?

Yes. Reference and review sources state that vaccination, when a sufficiently large share of a population is immunized, produces herd immunity by preventing circulation of infectious agents and indirectly protecting the unvaccinated; disease-specific reviews (influenza, pneumococcal, pertussis, SARS-CoV-2) report reduced transmission or herd protection.
