Joe Amon / Connecticut Public Radio With the mass vaccination of school employees set to begin this week, officials are concerned that teachers eager for shots will bypass the special clinics being planned by local health districts and instead schedule their own appointments on hospital websites or the federal portal. This could result in teachers and other school employees being on two lists — both the list for the local health district clinic and a hospital clinic — and, ultimately, vaccines going to waste, officials said. “The last thing we want is for superintendents to upload their rosters and the vaccine gets ordered and you assume everyone will be there the day of the clinic and then a lot of them don’t show up because they figured out how to get vaccinated quicker elsewhere,” said Fran Rabinowitz, executive director of the Connecticut Association of Public School Superintendents.
