Boy do you have booster questions! Let's answer some

Australians over 18 years of age who've waited six months from their second COVID vaccine will be given the chance to grab a booster shot if they want one.

While the focus will be on aged care and healthcare workers to start, yesterday, the expert panel on vaccinations approved the use of Pfizer booster doses.

And - at the moment - it's being sold as a boost, not a requirement to be considered "fully vaccinated"

Also on today's show:

* Only Pfizer is approved at the moment, but I want Moderna. Should I wait?

* What about mixing vaccines?

* Is Norman back at the gym?
