The Federal Government has jettisoned vaccine rollout targets and the Prime Minister says there's no point creating them anyway because COVID-19 "writes its own rules".

Instead, the government is "just getting on with it" in rolling out the coronavirus vaccine to the Australian population.

But with few details and limited vaccine supply, it's hard to tell at the moment how the Federal Government plans to do it.

However we do have AstraZeneca vaccines available and Pfizer is due to deliver many millions more eventually, so on today's Coronacast, a guess on how Australia's rocky rollout might be achieved by year's end.
