I haven't seen anything definitive on the extent the vaccinated can spread because the approval studies didn't look for asymptomatic cases or community spread.
Maybe there's data from Israel or something? What's your data source, DQ?
I haven’t seen anything “definitive” either because the science people are (understandably) slow to make anything “definitive.” But everything I’ve seen suggests that vaccinated people are very unlikely to be infected/spread.
E.g.

I think both of these stances are reasonable in our current state
The emerging data confirms what many of us thought would be the case—that not only do the vaccines stop symptomatic COVID, but they also make it highly unlikely that someone can even be infected at all.
I think the preponderance of the evidence supports the fact that vaccinated individuals are not able to spread the virus
Current guidance states that even fully vaccinated individuals should continue to wear masks and social distance. What’s the logic behind that?
Operationally, it is very challenging to know who is vaccinated and who is not, so the guidance in public places likely will be slow to change until more people are vaccinated. You can’t expect a cashier to ask for proof of vaccination.
Yeah and I get the referenced "operational" logic, but if that's the main reason, that's why it feels a little silly. Apart from some tenuous, macro level benefit at the societal level (i.e. "me wearing the mask indirectly encourages others (who are not vaccinated) wear the mask"), it feels like me wearing this mask isn't actually directly preventing anyone else from getting sick (or at least not at any statistically significant level).
I'm not saying I'm some ardent anti-masker. I've been religious about private/public mask rules for over a year now. It's a minor annoyance at most. But it does feel like a hollow exercise.
I think there's three main reasons that all work together:
1) the data still isn't conclusive (granted, it's very encouraging, but that doctor definitely said she "thinks" evidence points to no transmission and the study linked actually didn't track community spread (it also didn't account for J&J)
2) no way to know who's vaccinated + children and adolescents haven't been vaccinated (adolescents could be visiting or working at these establishments)
3) It's a minor annoyance at worst (that is also pretty cheap). Wearing a mask at Best Buy or Subway costs the economy like, nothing at all
the three are tied together, and really if you remove one of them from the equation (say conclusive data, 80% vax rates, or expensive inconvenient masks) then I'd agree are probably silly for the most part. Especially when adolescents and kids are able to get fully vaxxed.
