The federal government has put a stop to its deal to buy 50 million doses of the University of Queensland’s coronavirus vaccine after several trial participants returned false positive HIV test results.

The National Security Committee of Cabinet agreed to terminate the agreement following fears the revelation would severely damage Australia’s public confidence in the vaccination program.

“I think behind the scenes they’ll go on trying to develop a similar vaccine because it does hold so much promise.”
