The covid vaccine is mostly about you. A couple months of partial protection against infection is not saving the world.
> COVID-19 vaccine efficacy or effectiveness against severe disease remained high, although it did decrease somewhat by 6 months after full vaccination. By contrast, vaccine efficacy or effectiveness against infection and symptomatic disease decreased approximately 20–30 percentage points by 6 months.
This is the only place I could find in your source that mentions the efficacy numbers (not the drop in efficacy, which is what this is focused on), and it is only against severe disease.
The first one that came up for my search was this:

The findings section shows that by the time omicron was around, you were at around 43% against infection by 112 days.
That was then. What is it today? How many people do you need to jab to prevent one transmission? And how many people are doing that? Uptake is very low today.
There was a time when "the VAX is not about you!" was plausible. That time has passed.
Would have been even better if the effect on transmission had remained with the later variants, but unfortunately it didn't as the virus changed. Preventing transmission would be ideal, but that was just not possible with this particular virus and regular vaccines. But it still saved a lot of lives because of the very strong effect on mortality.
