Parents can get their children free immunizations without appointments this week for National Infant Immunization Week.
The Chicago Department of Public Health is encouraging families to check their children's immunization records and get them vaccinated by the recommended schedule.
Doctors say vaccine-preventable diseases are still a threat. Immunizations help protect children from 14 potentially deadly diseases like polio, measles, mumps and chickenpox.
Children whose parents cannot afford vaccines can get them free through a federally funded program.
National Immunization Survey Data shows vaccination rates are increasing. Now 73 percent of children are receiving six vaccines.
In Chicago, rates are higher than the national average with 75 percent of children receiving the full series of vaccines by age two.
