Melbourne has now been in lockdown for a week, and yet we're still seeing hundreds and hundreds of new coronavirus cases every day.

And the city's hotspot suburbs have had restrictions for even longer.

Health authorities are saying that the numbers are showing signs of some stabilisation but it's still too early to tell for sure.

So are the restrictions working and when should we start to see a decline in cases?

On today's show:

* Melbourne has been in lockdown for a week. Why haven't we started to see a decline in cases?

* Health authorities are talking about signs of stabilisation of numbers. Is that true?

* If the outbreak in NSW can be linked to Victoria, was NSW about to eradicate the virus?

And we received a bunch of comments on yesterday's show. Norman and Tegan respond to your concerns about elbow bumping, the efficacy of loose fitting masks and suggestions on how to get more people to wear them.

And we have some research from the New England Journal of Medicine about some results from Moderna's mRNA coronavirus vaccine trial. It seems to look pretty good, but there are some caveats.
