This didn't even occur to me. The title in the submission is cut short; most outlets including this article includes a "close to zero", "near zero" at the end, which has this overly cheery feeling (at least to me) that we can pat ourselves on the back, it's not just done but done-done, on to the next disease, huzzah. Whereas this whole thing is the result of a systematic nation-wide vaccination program that has been going on for quite a while (2008) and a study looked into its effectiveness and found that yes, this concerted campaign may have moved the needle on that population-level gauge.

It can happen elsewhere but it hasn't happened yet! Or who knows!
