That happens in breakthrough infections, and the goal of the vaccine is to reduce the number of breakthroughs, which it does successfully.
From the Lancet study linked in the article:
> The SAR in household contacts exposed to the delta variant was 25% (95% CI 18–33) for fully vaccinated individuals compared with 38% (24–53) in unvaccinated individuals.
That's a misleading line, referring to peak viral load. If you read the rest of the article (or probably the study abstract), you will see vaccinated people are infectious for less time.
