You'll note that insert doesn't say "to prevent infection".
As with HIV (SARS-CoV-2) versus AIDS (COVID-19), the disease you can get from the virus is not the same thing as the infection itself.

It was supposed to prevent the disease - basically postive test + symptoms. It didn't.
You called that very statement a "bizarre claim" upthread.
Try this: "Seatbelts prevent injury and death in car accidents."
They don't prevent every single one of them, but no one calls the above statement a lie. Your standard - requiring a vaccine be perfect at its purpose - is an invented one in bad faith to win an argument.
The discussion was about Covid. Covid is the disease (infection+symptoms). The vaccine was supposed to prevent you from "getting it".
That alone demonstrates the vaccine can help you not get it.
We have loads of evidence of it lessening symptoms; for a non-zero amount of people, that'll mean going from symptomatic to asymptomatic, i.e. SARS-CoV-2 infection but not COVID-19.
Vaccines have never been expected to be perfect in this regard; some polio vaccines can give people polio, for example.
(The idea that "turns out it only prevents hospitalization and/or death, not mild symptoms" is a bad result is also lunacy from the start.)
>>>> Vaccination was never about "not getting it".
Of course it was about whether the vaccine prevents you from "getting it" (it being Covid). The original claim was that it was 95% effective in preventing you getting it.
> We have loads of evidence of it lessening symptoms; for a non-zero amount of people, that'll mean going from symptomatic to asymptomatic, i.e. SARS-CoV-2 infection but not COVID-19.
We have loads of crappy evidence showing that (see below). Crappy means highly confounded observational data.
> Vaccines have never been expected to be perfect in this regard; some polio vaccines can give people polio, for example.
No one expects them to be perfect, but the original claims were they were supposed to be 95% effective in preventing Covid. Real world efficacy is no where near that. If there's any efficacy at all it is in the low teens.
[BTW, there's a huge debate about the oral Polio vaccine. The US stopped vaccinating with it two decades ago because of that risk]

It would be luncay if anyone actually claimed that.
The problem is that claiming that it prevents hospitalizations or deaths requires evidence. Reliable evidence.
A recent NEJM correspondence demonstrates quite vividly how terrible much of the evidence for that claim was:

(the original author's response is especially hillarious)
