Yes, there is a whole department of Medical Ethics now, for example, at the University of Oxford, part of the Medical Sciences division.
It is also the case that a decision was previously made against widespread vaccination of children against chickenpox; one idea behind this is given on the actual NHS website
"Being exposed to chickenpox as an adult (for example, through contact with infected children) boosts your immunity to shingles. If you vaccinate children against chickenpox, you lose this natural boosting, so immunity in adults will drop and more shingles cases will occur."
The linked article from Science Based Medicine quotes the JCVI as discussing that "There is an argument for allowing the virus to circulate amongst children which could provide broader immunity to the children and boost immunity in adults." which is a similar sort of idea.
I note that in most Western countries children are vaccinated routinely against chickenpox; there are very many arguments for this, and considerable benefit to children.
So with this thinking, in the UK children are denied protection from illness to benefit adults.
I think myself that this is highly spurious when applied to chickenpox, and even more so when applied to covid.
