From your cited Reason article:
> During a follow-up period beginning seven days after the second dose, vaccinated subjects were 92 percent less likely to test positive for the coronavirus, 94 percent less likely to develop COVID-19 symptoms, and 92 percent less likely to suffer serious disease. In other words, the risk of infection at this stage was much smaller than it was in the unvaccinated group. Although that risk was not completely eliminated, the CDC notes that "preliminary data from Israel suggest that persons vaccinated with Pfizer-BioNTech COVID-19 vaccine who develop COVID-19 have a four-fold lower viral load than unvaccinated persons," which implies that they are less likely to transmit the virus even when they are infected.
This seems consistent with what I wrote earlier.
Further, from the NPR article:
> Vaccinated people can also visit, unmasked, with people from another household who are not yet vaccinated, as long as those people are at low risk of serious illness from the virus. However, the agency said, vaccinated people should continue to wear masks when they're in public, avoid crowds and take other precautions when gathering with unvaccinated people who are at high risk of serious illness from COVID-19.
