Every day we get a news alert informing us exactly how many new cases of coronavirus have been detected in Victoria.

From there the rolling average is calculated and analysed as to how close Melbourne is to finally taking the next step out of lockdown.

On today's show:

* Norman re-thinks his earlier criticism about Victoria's contact tracing system

* Johnson & Johnson pauses its COVID-19 vaccine trial

* China announces first locally acquired cases in two months and announces it'll test a whole city
