Prisoners at the Guantanamo Bay detention center may be offered the COVID-19 vaccine months before it will be offered to most Americans, according to the Pentagon.

Clayton G. Trivett Jr., a prosecutor who pursued charges against five men accused of plotting the deadly Sept. 11, 2001, terror attacks, wrote to defense lawyers on Thursday that “an official in the Pentagon has just signed a memo approving the delivery of the Covid-19 vaccine to the detainee population in Guantánamo,” according to the New York Times. It’s unclear if the prisoners, including accused 9/11 mastermind Khalid Sheikh Mohammed, would consent to getting the vaccination.
