HARRISBURG (AP) – Some of Pennsylvania’s largest health systems are delivering a reality check after the state greatly expanded eligibility for the COVID-19 vaccine this week. Hospital officials say there’s not nearly enough vaccine to meet surging demand. Pennsylvania has expanded initial eligibility for the vaccine to include people age 65 and over as well as people 16-64 with serious health conditions. Some 3.5 million people are now eligible to receive one of the two vaccines.
