A data correction made by the U.S. Centers for Disease Control and Prevention last week made a dent in the state’s perceived progress on vaccinating the adult population. Under a data adjustment disclosed by the Pennsylvania Department of Health (DOH), the number of people considered fully vaccinated dropped from 73.7% of those 180and-older to 68.9% because of a reduction of about 1.2 million doses after removal of duplicate information and correction of data on first, second and booster doses.
