Teachers' association, district call for targeted approach By Madeline Hughes mhughes@andovertownsman.com  Mar 11, 2021 Mar 11, 2021 Teachers unions across the Merrimack Valley are celebrating access to the coronavirus vaccine after federal and state officials said educators and other school employees can receive their first COVID-19 shot within the month. Last week after an announcement from President Joe Biden, CVS pharmacies began opening up appointments to educators and other school staff in the Commonwealth. More appointments were made available starting Thursday, when Gov. Charlie Baker announced eligible to get in line at state-run sites starting March 11. Thus the hunt for appointments began.
