Article says vaccinated twice as likely to die. You say vaccinated are older group.
2021 applicable mortality table (used for pensions) has 20 year old males dying with probability .000256. To double that, a male has to be age 35 for .000515.
For a 30 year old, the q is .000397. Double that is age 44 at .000768.
For a 40 year old, the double q is at age 49.
For a 50 year old, the double q is at 57.

Are you suggesting the vaccinated cohort is between 6 and 15 years older than the unvaccinated?
Alternatively, consider a week where the rates are relatively close in June. The rates are 2.92 and 1.60, a relative rate of 1.825.
2.92 deaths out of 100,000 for a week is an annual rate of .00152. This is about the rate of a female aged 56. 1.60 x 52 = .00832, which is close to a female aged 51. An age difference of 5.
I don't know, and Berenson, who's lying about this, damn sure doesn't know, but considering that the vaccines haven't been approved for young people until lately those numbers seem reasonable.
We are only talking about the lowest of the four groups in the data: age 10-59. Now at first there was no vaccine even available to people under 18, then 16, then 12. And it's been well known that the younger you are the less likely you are to get Covid, and the less likely it is to hurt you.
So, given these two factors, yes, it's easy to believe the average age of the vaccinated (among those 10-59) is at least 6 years older than the unvaccinated in the same cohort.
