Dr. Theresa Gabana alleges she was unjustly fired in December 2021 after Tufts Medicine rejected her request for a religious exemption to the hospital’s COVID vaccine requirement. The suit calls for $5 million in compensation to Gabana, as well as an additional $1 million in punitive damages, according to the filing. Gabana worked at Tufts for nearly three decades before her firing. Tufts Medicine declined to comment on the pending litigation but said the COVID-19 vaccine has been 'a vital tool in reducing the risk of severe illness, hospitalization and death,' citing the effectiveness of federal and state vaccine mandates.
