Somebody appears to have forgotten that it is likely that a large proportion of us are going to get the virus one way or another, it is the way of things and cannot be avoided.
If somebody dies from the virus then they are by definition vulnerable; the only way for such people to be sure they are not killed by the virus is to live like a hermit until we have all been vaccinated (maybe years from now, maybe never)
Ultimately it is their choice, take a chance and get on with life or lock away and hide.
There will be more deaths whatever we do, there will only be unncessary deaths if we go berserk, infect huge numbers in a short time and overwhelm the NHS leading to the death of people who would otherwise have survived - I would suggest that this is pretty unlikely.
So yes, their will be deaths - but there is nothing practical that can be done to prevent them without totally destroying our economy, and the effect of destroying the economy would lead to many more deaths by different causes - starvation, civil disorder, collapse of the state and the NHS.
