Why Australia just canceled an order for 51 million doses of a COVID-19 vaccine

Australia cancelled an order for 51 million doses of a COVID-19 vaccine being developed by CSL Ltd. and the University of Queensland after trials ran into difficulties. The government said Friday it’s replacing most of the CSL doses with more purchases of other planned vaccines.

The CSL failure shows that despite the groundbreaking progress by Pfizer Inc. and Moderna Inc. in producing an inoculation, the path to a successful vaccine remains difficult.
