Evers said the idea was that a separate site would prevent service issues because transit employees wouldn’t have to wait in line at one of the state’s mass vaccination sites. “If the state is to put us in a big facility, like Gillette [Stadium], they can’t manage the disruption in service that it could cause,” he said. Starting next week, teachers will be eligible for the coronavirus vaccine -- but how will they be able to sign up with no available appointments in sight? More than 300 transit workers have already caught COVID-19, and one died, Evers said.
