When the various states and territories report their daily vaccination rates as a mix of single and double doses, should they perhaps also be adding in third doses?

The COVID-19 vaccines in Australia are currently limited to two doses, but so far only immunocompromised people have been approved to get a third shot.

So should that be extended to older people and perhaps healthcare workers who got their vaccine in March or April?

On today's Coronacast, all your questions about the third dose including waning protection from Astra and Pfizer, timing and when to count it all from.

Also: thank you to all our listeners - especially those who've listened to all 400 episodes of Coronacast. You are champions!
