The next phase of Australia's vaccination program began yesterday, and millions of people aged over 50 are now eligible to receive a vaccine.

But many are still finding the booking process difficult and confusing, and while vaccines are available it can take a bit of work to find one.

Before now, only the vulnerable and front line workers have been eligible, so health officials and experts will be hoping that finally we'll see a dramatic increase in the COVID-19 vaccination rate.

So will we finally see a jump in vaccinations?

Also on today's show:

* I've heard that the vaccine immunity lasts only for 6 months. So does that mean that I'll need another 2 shots of the vaccine when Australia finally opens up, and I want to travel?

* I am a First Nations person who is 36 with no other comorbidities. Is it clear yet when Pfizer will be available to me?
