“The animals routinely get other vaccinations. Many of the mammals are trained to present themselves to our animal care staff for minor medical procedures, including vaccinations. We’re both thankful and relieved a special vaccine is now available to protect against COVID-19,” said Scott Carter, chief life sciences officer for the DZS.

According to zoo officials, no animals at the Detroit Zoo have contracted COVID-19.
