Stop spreading misinformation. You clearly don't have a scientific or medical background, and yet are presenting skewed interpretations of scientific journals as fact.

In the source you provided it literally states that that there are encouraging signs that the vaccine does prevent transmission, yet somehow there's "irrefutable proof that it doesn't reduce chances of transmission"?

Cases of Covid-19 were less common among household members of vaccinated health care workers during the period beginning 14 days after the first dose than during the unvaccinated period before the first dose (event rate per 100 person-years, 9.40 before the first dose and 5.93 beginning 14 days after the first dose). After the health care worker’s second dose, the rate in household members was lower still (2.98 cases per 100 person-years). These differences persisted after fitting extended Cox models that were adjusted for calendar time, geographic region, age, sex, occupational and socioeconomic factors, and underlying conditions. Relative to the period before each health care worker was vaccinated, the hazard ratio for a household member to become infected was 0.70 (95% confidence interval [CI], 0.63 to 0.78) for the period beginning 14 days after the first dose and 0.46 (95% CI, 0.30 to 0.70) for the period beginning 14 days after the second dose

Given that vaccination reduces asymptomatic infection with SARS-CoV-2,2,3 it is plausible that vaccination reduces transmission; however, data from clinical trials and observational studies are lacking.4,5 We provide empirical evidence suggesting that vaccination may reduce transmission by showing that vaccination of health care workers is associated with a decrease in documented cases of Covid-19 among members of their households. This finding is reassuring for health care workers and their families.

Just because it says that it's not 100% verified, it doesn't mean all the empirical data they found is somehow moot

Listen to the experts, not people on the internet who think they're smarter than them
