WASHINGTON (Reuters) - More than two dozen members of the U.S. Congress on Wednesday called on federal prison and health officials for details about how inmates will be vaccinated for COVID-19, questioning whether the most vulnerable prisoners will have priority access. In a letter to Federal Bureau of Prisons director Michael Carvajal and Centers for Disease Control and Prevention chief Dr. Robert Redfield, 26 lawmakers, led by Democratic Representative Bobby Scott, expressed concerns about the prison system’s existing plan for vaccine distribution.
