How does government agencies know whether a death is vaccine related or not?

I have read a few articles about deaths shortly after the Covid vaccine, and in all of them there were the reassurance that the death was not related to the vaccination, but there hasn't been any explanation why.

What is the technique used to determine whether a death was related to a vaccine or not and why is it not provided so the public can be put at ease with scientific data?

Here's the dealio: we don't know for sure but we have a lot of science saying it doesnt.

Each day you have various opportunities to die randomly. Heart attack, stroke, aneurysm for instance. When someone does die under strange circumstances we do an autopsy and find out why.

All of the history we have on how many people die of what cause gives us a rate. For instance x number of people die each day from y disease.

This rate gives us a baseline and we monitor it to see if there is an increase.

So far the number of people who have died after taking a covid vaccine has not show any baseline increases. Since the numbers remain at their expected levels, we can safely say the covid vaccine isn't causing death in people.
