The previous time they measured this, as stated in the article, the county with the lowest vaccination rate had the highest incident rate. All you can say is that the _rank_ of a county by incident rate seems uncorrelated with its vaccination rate _given_ just these two points of evidence. There are 26 counties and vaccination stats and incident rate stats going back nearly a year which suggests this sample size (2) is too small to draw any kind of useful conclusions about the overall relationship. In any case it makes little sense to look correlations with the _rank_ (within the counties of Ireland) of the infection rate. The rank will have much higher variance than the underlying rate if the numbers are low for example which could be responsible for more outliers and it's outliers that attract media reports which can create a misleading impression.
