The deaths are likely to be low at first because a) the numbers prevalent are still low (currently about 2-6% of the likely maximum in the Spring, and these were even lower 4-6 weeks ago).
b) the shielded people were told to continue shielding till 1st August and have only fairly recently emerged blinking into the sunlight, as it were.
Now that schools are back, with lots of shielded families having a member/s pressurised to return to work to study in them, with no social distancing, poor safety measures etc.
So covid will spread in the schools, the shielded will start getting infected and then they will start dying.
And really, no one seems to give a fucking shit.
