As a result, the findings suggest that prevention and mitigation measures should be implemented regardless of vaccination status for those living in high-risk environments or who have large exposure to the virus.
No info on actual shedding.
Stigmatizing the normal is not warranted, says guy doing his damn job:
There is increasing evidence that vaccinated individuals continue to have a relevant role in transmission. In Massachusetts, USA, a total of 469 new COVID-19 cases were detected during various events in July, 2021, and 346 (74%) of these cases were in people who were fully or partly vaccinated, 274 (79%) of whom were symptomatic.
