Wide disparities among counties continue as Pennsylvania's troubled rollout of coronavirus vaccines unfolds unevenly across the state.
In counties that have seen the most progress so far, residents have been vaccinated at two to four times the rate in counties at the bottom of the list, an LNP | LancasterOnline analysis of state data shows.
In the seven counties with the most success, 15% or more of the population was partly or fully vaccinated as of Tuesday. Rural Montour and Cameron counties led the list at 32% and 22%, respectively.
Meanwhile, in seven counties at the bottom of the list, the rate remained below 7%. Potter and Fulton counties came in last, with only about 5% of their populations at least partially protected.
Lancaster County ranked 43rd among 66 counties, with about 49,000 people — or 9% of its population — either partially or fully vaccinated as of Tuesday, Feb. 16. That was better than any of its five bordering counties, the analysis shows.
Chester County ranked 46th, at 8.8%; Lebanon was 49th, at 8.4%; Berks was 51st, at 8.2%; York was 54th, at 8.0%; and Dauphin was 61st, at 6.7%.
The analysis covers the cumulative progress of the program since vaccinations first became available in December.
Below are the rankings for every Pennsylvania county except Philadelphia, which is running its own vaccination and data collection program. Data is from the state Department of Health as of Feb. 16, with population figures from the U.S. Census Bureau.
The data is based on residency of the person vaccinated, not where they received the vaccine. The numbers do not include people who were vaccinated in Philadelphia, out of state or at a federal facility.
