BOURNE — The Cape's legislative delegation sent a letter to local school superintendents telling them not to expect an educator-only vaccination site this side of the bridge any time soon, even as state officials Wednesday called for such local clinics to be held. “We have asked the Baker-Polito Administration about setting up educator-specific sites and, so far, we have received a hard NO,” the letter dated Tuesday read. The eight legislators urged teachers and other school employees not to wait for a vaccine but to avail themselves of appointments through CVS, the state’s seven mass vaccination sites and other currently available locations.
