The Pennsylvania Department of Health says a data collection error wrongly added about 500,000 total COVID vaccine shots to the state’s reporting system.
It came after DOH staff were trying to link first and second doses to individuals in each county.
At a local level, the number of people with at least one shot of the vaccine in Butler County nearly dropped by 50 percent.
Last week the data showed that over 10,000 county residents were at least partially vaccinated, but now that number sits at just shy of 6,000. The number of fully vaccinated individuals in the county is still over 91,000.
