It seems that every time we talk about the timeframe of Australia's borders reopening to the world, the estimated date slips further into the future.

In this week's budget, the government indicated that borders will probably remain shut until 2022 at least.

And Qantas has also pushed back its plans to restart international flights by at least two months.

So on today's Coronacast, what could be behind the reason for the slippages of border reopenings?

Also on today's show:

* Will we really need to get a vaccine every year for covid 19 for the foreseeable future?

* Children don't usually get severe COVID-19, why am I seeing reports of kids dying in India?

* If a combined coronavirus and flu vaccine is being developed, why can't existing coronavirus and flu vaccines be given at the same time?

* I'm due for the second shot of Pfizer next week and am feeling a bit under the weather. What do I do?
