The government has never defined clinical risk by the groups mentioned.
I suppose it couid just be appalling DM reporting.
But if the government mean the groups it has defined as highest risk (shielded, them 'flu jab' vulnerable) then it is easy to say so.
Becase it's wrong to be reporting priority to a lower risk group, whilst ignoring those known to be at substantial higher risk.
There are however, with new vaccines, sometimes good reasons to not begin with those living with certain other conditions and the pregnant, but those reasons also extend to the elderly. If an initial group were being chosen be they were the lower risk guinea pig first wave, that could also easily be reported.
Following on from an earlier poster, the airbrushing out of the most vulnerable 'shielded' population from policy discussions - look at how the update originally due w/c 15/06 is still expected 'shortly', and the absence of consideration for shielded pupils in schooling matters - is reaching a concerning level.
