‘Harmonised system’ needed for vaccine passports

Cyber Security Cooperative Research Centre’s Rachael Falk says vaccination passports would have to be implemented in a “harmonised system”.

It comes as tech experts have raised concerns on vaccine passports, with fears they can be easily faked.

"It’s got to be developed in a way that’s verifiable," Ms Falk told Sky News host Peta Credlin.

"It’s absolutely got to have security baked in."
