Melbourne recorded its second worst day yesterday with 374 new cases of coronavirus.

It's also been nearly two weeks since the city-wide lockdown was reimposed, but as yet there has been no reduction in new cases and it's unclear whether the curve is flattening.

Restrictions seemed to work a lot faster the first time, so what’s going on?

And you asked for it: we have Norman's explanation and breakdown of the promising results of the Oxford University coronavirus vaccine.

On today's show:

* Shouldn't we be seeing a reduction in new Melbourne cases by now?

* Is it time to impose tighter restrictions?

* Why are we not being advised to soak reusable face masks in ethanol?

* I'm a mask newbie. I experienced a suffocating feeling, like I was in a stuffy room with humid stale air. Do you have any advice?

And you have some comments about not inhaling scotchgard, questions about if we're anti-Queensland because we forgot to mention them yesterday and was Norman grumpy on Monday.

Also today is our 100th episode! We wouldn't be here if it wasn't for you or your amazing questions, so thank you for listening!
