No we haven't.
"Overall, the likelihood of household transmission was approximately 40 to 50% lower in households of index patients who had been vaccinated 21 days or more before testing positive than in households of unvaccinated index patients"
Then you add in the fact that vaccinated people are much less likely to become infected then unvaccinated, and thus incapable of transmission (anywhere from 30-95% reduction depending on vaccine used, prevalence of delta, timing of vaccine, and presence of booster). Also I fail to understand why eating in a restaurant is different then attending school. In fact, I'd argue the opposite, that the latter is much more important then the former.
