Why in 2023 people still believe that C19 mRNA prevents infecting others? This myth has long been classified as wrong (unlike advertised in the beginning of its rollout)
Point has always been that people who are less ill, less severely ill, for a shorter duration, with fewer or no symptoms, have lower chances of infecting others.
The urge to simplify is great but it causes these weird discussions like "does the vaccine prevent (all) infection" or like what we have here.
The most recent research on the types of antibodies the vaccines create vs natural infection are showing the opposite: it causes our bodies to treat the virus more like an allergy, reducing the symptoms while clearing the infection much slower. This gives more chance to infect others, not less.

The fact that we now know they were lying is why we're in this situation to begin with.
Some of us knew they were lying from the start and had a very frustrating few years: Pfizer made no claims about infection/transmission, just symptoms, because they never tested for infection/transmission. That claim popped up out of nowhere a few months after the vaccines were available.
Because it does. Your chances of getting and spreading COVID for the 3 months after you get a vaccine drop dramatically.
"Although vaccination still lowers the risk of infection, similar viral loads in vaccinated and unvaccinated persons who are infected with the delta variant call into question the degree to which vaccination prevents transmission."
Not to dispute your claim, but to put it into context. But apart from that, I am out of this debate.
"Becoming sick with Covid" and "becoming infected with Covid" are very different things.
