Pennsylvania school superintendents, school boards and teachers unions are coming together to ask Gov. Tom Wolf to prioritize school staff for the COVID-19 vaccine. The education groups call it an “absolutely essential” step toward reopening schools and keeping them open. More than 4 million people in Pennsylvania are currently eligible for the vaccine, with teachers and other essential workers next in line. In a letter to Wolf on Thursday, the education groups contended that “school staff members and students are in a uniquely dangerous position” and need to be vaccinated right away. The Wolf administration says it’s following federal government guidance on vaccinations.
