This is a finely balanced argument and everyone will have a different take so there is no one position on this. For me, there are truths I want to know and some I don't: Do I want to be told, if I am ill, that I will die in n days time? No. Let me die in ignorance. But some will want to know so they can do the most with their remaining time (e.g. visit every bar in the city at least once more). Do I want to know that a person within my area has an illness that might be dangerous to me? Sure (it may temporarily avoid my first dilemma above!) - at least it gives me a chance to find preventative measures. Should I be told the death rate from a vaccine? Definitely - I am the one should be able to decide if I wish to take the risk. But, an issue touched on here by others, should people be allowed to refuse vaccination, if they feel it has a risk? Well, they should be told the truth about the risk but the common good prevails - if there is a need for a well-vaccinated population to stop the spread of a deadly disease then perhaps it is no different to conscripting people to defend a country against an enemy attack. But, as usual, everyone has their own take on everything - and so they should.
