Thousands of Covid-19 vaccine doses in danger of going to waste PHILADELPHIA (KYW) — The clock is ticking. About 4,000 doses of the COVID-19 vaccine are in danger of going to waste at FEMA’s mass vaccination site at the Pennsylvania Convention Center. The line outside the Pennsylvania Convention Center on Wednesday was nothing compared to just a couple of weeks ago when people struggled to find a vaccine in the city of Philadelphia. Still, Luis Ramirez wasn’t taking any chances and made sure he was the first to get his shot at the convention center Wednesday morning. “I want to make sure that I’m safe for myself and safe for others,” Ramirez said.
