Let me approach it from another angle. Pre-vaccine, it appears that Covid roughly doubled everyone's all-cause mortality.[1] Like it killed 30 year olds at a much lower rate than 90 year olds, but 30 year olds have a much lower baseline mortality to begin with. This isn't an exact relationship, but approximately about double mortality across the board. (Even interestingly enough men's excess Covid death rate is about in line with their general mortality vis-a-vis women.)
The vaccine appears to reduce the mortality risk of circulating Covid by about a factor of 100X. There's very little reason to believe that it substantially shifts the relative mortality burden between groups. So, post-vaccine Covid increases all-cause mortality broadly by about 1%. That translates into less than 1 month of lost life expectancy.[2]
