The British Government says it has detected a new strain of coronavirus that is rapidly increasing in prominence in southern England.

Viruses can and do change all the time in ways that can both help or hinder the strain depending on what the mutation is.

We've heard about new coronavirus variants several times: think back to claims of a new, fast moving, wildly infectious strain in South Australia's Parafield cluster.

So on today's Coronacast, what could be happening in the UK? And is it something to worry about this time around?

Also on today's show:

* What's the latest with the Oxford vaccine? Is it currently up for approval?

* What happens if they vaccinate someone who's already had COVID-19?
