It's been a tough couple of days for health authorities in South Australia, especially surrounding the case of the COVID positive man who went out to lots of places.

Health authorities initially said he had broken quarantine by going shopping, before admitting that as a casual contact he hadn't actually been told to stay home.

It turns out that the man did everything that was asked of him, and it was the authorities who got the message wrong.

So on today's Coronacast, why getting the information right is so important - and particularly in a pandemic.

On today's show:

* We haven't had a case of coronavirus in town for over 6 months now. My school age kids often catch colds and I've been getting them swabbed each time. Do I need to continue having them tested?

* We've heard a lot from the companies about the effectiveness of their vaccines, however could you comment on the safety component of the trials?
