The changes are detailed in the zoo’s $500 million Next Century Plan, which is in anticipation of the zoo’s 100th anniversary in 2034. Dr. Mike Adkesson, president and CEO of Brookfield Zoo, joined “Chicago Tonight” to discuss the plan.

The 11-year-old tiger had received her first dose of a COVID-19 vaccine developed for animals. The zoo is now awaiting test results for other big cats that are exhibiting symptoms similar to the infected tiger’s.

Animals at Brookfield Zoo have begun receiving COVID-19 vaccinations, with Lincoln Park Zoo soon to follow, as federal and state officials approved the use of the inoculations.
