It's been a while, but an Australian state is again dealing with an outbreak of COVID-19.

Queensland detected a positive case of the so-called UK variant - B117 - on Thursday. A second case was detected over the weekend that may be the link to the existing cluster.

In a positive sign, the number of tests in Queensland jumped over the weekend - but considering how long the person was infectious out in the community, it'll be a few more days before we can see how far it might have spread.

So on today's Coronacast, last time this happened the city was plunged into a three day lockdown. What's different this time?

Also on today's show:

* Clinical advice from Victorial about AstraZeneca and thrombosis

* I had my jab of AstraZeneca and I had a fever and headaches. I gather this is normal. Why do we get these symptoms?

* Does taking paracetamol after vaccination reduce the efficacy of the vaccine?
