All year we've been hearing a vaccine was 12 to 18 months away, and annoyingly it never seemed to change.

But when you talk to the experts, it seems we're much closer to the next vaccine milestone than you might expect.

And that milestone is finding out if any of the good quality frontrunner candidates work or not. The timeline? Possibly only 4-6 weeks away.

On today's Coronacast, we're joined by vaccine expert Terry Nolan who describes what the vaccine front might look like by Christmas.
