Needham superintendent: 'Thrilled' for teachers; 'sometimes ticked' at state's COVID directives Wicked Local Starting March 11, teachers, early educators, and school staff members will be able to try to sign up for COVID-19 vaccine appointments through any of the state's 170 vaccination sites and mass vaccination sites plan to block off certain days to vaccinate educators, Gov. Charlie Baker said Wednesday morning. The announcement comes as Baker and Education Commissioner Jeff Riley push for full-time, in-person education at all Massachusetts elementary schools by next month and after teachers unions ramped up a campaign backed by legislative leaders to get more of their members vaccinated sooner.
