“Now we know that the vaccines work well enough that the virus stops with every vaccinated person. A vaccinated person gets exposed to the virus, the virus does not infect them, the virus cannot then use that person to go anywhere else.”

Except that we now know the shots have/had a negative efficacy – those with the shots are 2x more likely to get Covid than the unvaccinated:

I read the study. The researchers did not use random sampling procedures as is normal for such studies. There were 913 people studied, a small sample for such studies. The data concerning getting covid and getting vaccine shots was self reported by the 913 individuals. There was no attempt to verify the accuracy of the participants claims.
There have been dozens, or perhaps hundreds of formal clinical studies performed in compliance with study standards which show adequate effectiveness for the vaccines concluding that they are not perfect but do reduce the chance for infection and severity of the disease if infected. All in all, this Japanese study is not very convincing.
