HARRISBURG (AP) – Four of PA’s seven most heavily populated counties are airing their unhappiness over the size of their allotment of COVID-19 vaccines. Leaders of Bucks, Chester, Delaware, and Montgomery Counties said their smaller-than-expected allotments have led to long waiting lists and cancellation of second-dose appointments. The PA Department of Health says the problem with distributing the vaccine is that there is not enough to meet demand and that there has been no intentional shortchanging of any particular county. It said vaccination rates in the four counties are at or above the 15% rate across the rest of the state.
