DEPTFORD TWP., New Jersey (WPVI) -- Vaccination sites in Pennsylvania and New Jersey are not only rescheduling appointments missed because of recent winter weather, but also anticipating a shortage of doses due to delayed shipments. John Testa of Brick Township, New Jersey received his second shot Friday at the Gloucester County mega-site at Rowan College of South Jersey. His appointment was delayed by one day because of weather. "I'm so happy. I had an appointment yesterday at 8:15 a.m. and I couldn't get here," said Testa. While county officials say anyone who missed a Thursday appointment will be accommodated through the weekend, they're also looking ahead to next week and the impact of delayed shipments.
