I'm not sure why people keep saying this. The original studies did not study if the vaccine prevents spread, that is true. I'm not certain myself, but I believe that studies done based on COVID spread in countries where vaccination rates are high (at least Israel) point to the direction that it prevents spread as well. Are these not valid data points?

There was also the Seychelles data point which had the highest vaccinated rate and then had a large outbreak after.

  Which vaccine did they use? The CDC says the strongest evidence for preventing spread is for the mRNA vaccines.

    The vaccine produced by China's Sinopharm company: https://duckduckgo.com/?q=sinopharm+seychelles&t=fpas&ia=web https://duckduckgo.com/?q=sinopharm+seychelles&t=fpas&ia=web

      Not entirely accurate. From the top article in your search: "Among the vaccinated population that has had two doses, 57 percent was given Sinopharm, while 43 percent was given AstraZeneca."

  The outbreak was mostly in unvaccinated people, and there was no background of prior infections (they never had a first wave). Besides, studies on healthcare workers, who are tested regularly, showed a clear reduction in transmission.
