With growing emphasis on getting students back in schools, teachers and school staff will receive the first doses delivered to Pennsylvania of the newly approved one-shot Johnson & Johnson vaccine, under Gov. Tom Wolf’s plan being released today. State officials expect a first shipment of 94,000 doses of the Johnson & Johnson vaccine to arrive this week as school districts face pressure to bring students back to classrooms for in-person instruction. Vaccination at more than two dozen sites around Pennsylvania could begin as early as next Wednesday. Teachers currently are grouped in Phase 1B, along with child care workers, police, firefighters, grocery store workers and others considered to be essential workers.
