COVID-19 Vaccine Distribution

According to the Pennsylvania Department of Health, hospitals began receiving shipments of the Pfizer-BioNTech COVID-19 vaccine the week of Dec. 14 and Moderna COVID-19 vaccine the week of Dec. 21. The Janssen (Johnson & Johnson) COVID-19 vaccine was first allocated to Pennsylvania the week of March 1, and the commonwealth is using it for a special initiative involving educators.

Officials state that while vaccine supply from the federal government remains limited, the Department of Health is working to ensure the vaccine is provided in a way that is ethical, equitable and efficient.

The Commonwealth’s “Your Turn” tool provides a way to register to be alerted when it’s your turn to be vaccinated.

Editor’s Note: Initially, MyChesCo pulled county-specific COVID-19 data from the Chester County Health Department’s COVID-19 Dashboard. However, over time, that data became inconsistent and unreliable. Therefore, except where noted, MyChesCo is using data from the Pennsylvania National Electronic Disease Surveillance System (PA-NEDSS) as the primary data source for daily updates.
