We don't "know" either of those things with any degree of certainty whatsoever. The Bangladesh mask study that proponents like to point to showed a mere 10% reduction in spread, and the 95% CI included "no effect" and "makes it worse." As far as vaccination goes the picture is also unclear (its effect on transmission was never studied in the trials, which are the only true RCT we ever had), but the CDC itself has said in one study that "the vaccinated may transmit the Delta variant as easily as the unvaccinated." How long are you planning to maintain your vax+mask expectation? What is the offramp back to normal life for you?
