The U.S. Department of Justice has reached a settlement agreement with Rite Aid that requires the drugstore chain to alter its online COVID-19 vaccine registration portal so that more disabled people can access the site, including people who must use screen-reader software and those who have difficulty operating a mouse.

The agreement comes after the DOJ instituted a compliance review of the retailer’s vaccination registration portal to determine whether disabled people could access and use it, according to the settlement agreement. A DOJ official in a news release about the settlement emphasized the vital nature of the site, calling it a means for scheduling “potentially lifesaving vaccine appointments.”
