Rep. Ayanna Pressley said on Sunday that she would fight for prison inmates, along with other groups, to get priority for receiving the coronavirus vaccine.

“I’m going to continue to fight for our most vulnerable — communities who have been disproportionately impacted by the virus, for our health care workers, for our essential workers, for incarcerated men and women to be prioritized in the distribution of the vaccine,” she said, during an interview with CNN.

The coronavirus has been an especially thorny issue for prisons given the close quarters. Due to virus-related restrictions, prisons have released thousands of inmates since the pandemic started.
