Two suspicious packages at the University of Saskatchewan on Tuesday have been found to be not dangerous.
One of the packages was sent to the Vaccine and Infectious Disease Organization International Vaccine Centre (VIDO-InterVac) through the campus mail service.
VIDO-InterVac is one of many research facilities in the world currently working to find a vaccine for COVID-19.
The wing of the building where the package was located was cleared of all staff and closed.
Hazmat teams performed air quality tests and tested the package. It was found to be safe.
Access to VIDO-InterVac by Perimeter Road and Veterinary Road was shut down and the public was advised to stay away.

Later, a second suspicious package was found in a university administration building.
Hazmat teams tested the second site and it was also found to be safe.
Crews wrapped up their work by 8:40 p.m. CST.
