It's been nearly a year since coronavirus burst into the world's consciousness, and finally mass vaccination campaigns have started.

Over the weekend, Russia started vaccinating people. The UK will begin in the next few days and the US will hopefully follow later this month.

And already, hundreds of thousands of people in China have received vaccinations.

But on today's Coronacast, not every vaccination program is the same, and one of the big differences is that some of the drugs have gone through the full three phases of human trials, and others have not.

Also on today's show:

* The difference between emergency use approval and approval in an emergency

* Two people manage to escape hotel quarantine

* No new cases from the NSW hotel quarantine outbreak so far

* And some more reflections on things you'll be doing differently once COVID is less of a concern
