OTTAWA — A union representing federal prison guards says vaccinating them against COVID-19 should be a priority, given their front-line role in correctional institutions. Members should be inoculated at their workplaces as quickly as possible, said Jeff Wilkins, national president of the Union of Canadian Correctional Officers. The call came Wednesday amid word from the union that the Correctional Service would begin vaccinating inmates this week. In a statement late Wednesday, the Correctional Service said it expected to begin vaccinating "older, medically vulnerable federal inmates" Friday against COVID-19 as part of the first phase of the vaccine rollout, as recommended by the National Advisory Committee on Immunization.
