One person was taken in stable-but-serious condition to University of Chicago Hospitals, along with three others who were in good condition, according to the fire department.
Another two people were taken in good condition to Saint Bernard Hospital, the fire department said.
The accident shut East 67th Street between South Champlain and South St. Lawrence avenues, police said.
