The Rev. Jesse Jackson, 79, and his wife, Jacqueline, 77, have been hospitalized after testing positive for COVID-19. 

The two were “responding positively to treatments,” their son told The Associated Press. 

Jesse Jackson, a famed civil rights leader and two-time presidential candidate, is vaccinated against the virus and received his first dose in January during a publicized event. He and his wife are being treated at Northwestern Memorial Hospital in Chicago.

A protégé of the Rev. Martin Luther King, Jackson was key in guiding the modern civil rights movement. Despite having been diagnosed with Parkinson’s disease, Jackson has remained active, and has advocated for COVID-19 vaccines for Black people, who lag behind white people in the United States’ vaccination drive.
