This isn't just about science; this is about trust. Australians didn't trust the minister for health enough to sign up to the COVIDSafe app. He spent $14 million on that app, and half of that was on advertising. A year later, it's only found a handful of COVID contacts. If Australians didn't trust the health minister enough to put an app on their phones, why would they trust him enough to put a vaccine in their arms?
