Как я поняла, автор считает, что разницы и сейчас практически нет. То есть вакцинация не дает особо никакой отдельной "защиты от смерти" или "от госпитализации", только защиту от инфицирования, а все остальное - ее следствие.

When you actually take a look at who was infected and who died by age group, the idea of additional protection disappears for most.

36 of 84611 in the unvaccinated versus 0 in 1066 in the vaccinated group. 36 in 84611 is roughly 1 in 2350, but we only had 1066 infected in the vaccinated group. There is not enough information to claim the death rate per infection is higher or lower, and that uncertainty is indicated in the graph above.

For ages 45-64, there again isn’t enough evidence to conclude that the infection/case fatality rate is any different, but as the bluish dots indicate, the numbers we have actually lean towards a higher death rate among the vaccinated.

The silver lining though is that among those 65 and over, the observed death rate in the trial gives us decent reason to believe that maybe the vaccine can reduce the death rate for this group. Since they were the most vulnerable all along, this is a promising result.
