Excerpted from the above link is something
particularly interesting to us codgers....
It is also important to consider the ages of those who are dying. People 65 and older make up the group that is both the most likely to be vaccinated (and boosted) and the most likely to die of COVID. (Being older is one of the biggest risk factors for severe COVID because the immune system weakens with age.) So when you separate the age groups, it becomes even clearer that vaccination reduces the risk of death. And because immune protection from vaccination wanes with time, and because some older people do not mount a good immune response to the primary series, being boosted reduces that risk even further.
