WORCESTER—With less than a week before residents 75 or older become eligible to receive their first dose of the COVID-19 vaccine, city councilors said they have been getting anxious phone calls from residents about the process, and they don't know what to tell them. At-large Councilor Donna Colorio said that since Monday, when Gov. Charlie Baker announced the change to the state's phased vaccine rollout that will allow the seniors to get vaccinated, she has heard from many elderly residents. She said they are scared and confused, and wanted to know who they can call, or where they can go. She said many residents who have trouble getting out are concerned they will be passed over.
