As Australia's march towards higher and higher rates of vaccination rolls on, more and more ideas are being thrown around to try and convince eligible people to get the jab.

Yesterday, fruit and vegetable processor SPC became the first Australian company to mandate vaccines for all onsite staff and visitors.

It raises the question: if SPC can do it, why aren't we seeing similar mandates for healthcare, aged care and child care workers?

At the moment, the answer is ... complicated, as you'll hear on today's Coronacast.

Also on today's show:

* Kids and long COVID. Good news!

* How effective are masks? I've read 80 per cent, then heard someone say 40 per cent. What's the latest research?

* Norman has often said that 80 to 90 per cent of people don't pass on the virus. I don't have any special data on this but that *feels* way too high. Is it?
