I don't think it's helpful how irate people get about the UK government's failings. Yes there are plenty but this is a whole new situation and there are plenty of other countries making mistakes.
Before you ask - I'm not from the UK, but that means I have insight what happens elsewhere,
So to start -
The Eu has been slow in vaccine acquisition
In Austria, vaccinations could not start yet in some areas as not enogh needles (!) had been ordered
Countries with the most severe lockdown did not necessarily solve the Problem (Spain)
Countries who had supposedly excellent track and trace also had a second wave (Germany)
Anyone got other examples?
