For someone who's been quick to repeatedly accuse others of failing to properly read and comprehend posts, you've consistently ignored the point repeatedly made by multiple people that vaccination has a protective effect against infection in the first place, reducing people's chances of being infectious
at all and hence having a protective effect for others.

That's the latest COVID-19 vaccine surveillance report from the UK Health Security Agency.
See the section on 'Effectiveness against transmission', that begins:
As described above, several studies have provided evidence that vaccines are effective at preventing infection. Uninfected individuals cannot transmit; therefore, the vaccines are also effective at preventing transmission. There may be additional benefit, beyond that due to prevention of infection, if some of those individuals who become infected despite vaccination are also at a reduced risk of transmitting (for example, because of reduced duration or level of viral shedding).
The benefit is categorically
not just a personal one; being vaccinated has been shown in multiple studies to reduce the chances of onward transmission. Why are you refusing to acknowledge that?
