Search and sort this table for immunization levels for more than 3,000 Chicago-area schools, for six immunizations that protect people from eight major infectious diseases, posted by the Illinois State Board of Education, for the 2020-2021 school year. State law says all rates need to be at least 90%. To date, ISBE has not posted any rates for the 2021-2022 or 2022-2023 school years, and has not posted any rates at all for hundreds of schools, for the past 3-1/2 years. NBC5 Investigates has filed public records requests for the most recent immunization rates and will update these charts as soon as we get those more-recent numbers.
