There have been growing tensions between state governments and the Commonwealth about the national road map to reopening the economy and the country.

With most of the eastern seaboard still in lockdown, Prime Minister Scott Morrison stressed on Monday we “can’t stay in the cave forever” once vaccination targets of 70 per cent and 80 per cent are reached.

But those targets only include the eligible population, currently those aged over 16, which would leave millions of children unvaccinated.

Today on Please Explain, federal health reporter Rachel Clun joins Bianca Hall to discuss the federal vaccination rollout, and when we can expect younger children to be eligible for vaccines.
