CSL bets on emergency vaccine by mid-2021, but warns failure is a big risk

One of the local rivals in the race to kill the virus predicts a vaccine could be ready for emergency use by mid next year. 

The blood products company CSL is working with the University of Queensland and other potential partners, but warns there's a risk that no vaccine will end the pandemic. 

CSL chief executive Paul Perreault tells ABC's Peter Ryan there are complex technical and regulatory hurdles ahead.
