There is a slight chance, but it is not different than an unvaccinated person having an asymptomatic case (which is also common). That being said, the possibility of infecting others is much less when you don't have symptoms.
> The risk of spreading the Delta infection soon after vaccination with that jab was 42%, but increased to 58% with time.
42% (and even 58%) is still a huge improvement since the article says that the likelihood that an unvaccinated person will spread is around 67%.
The R0 value for Delta is between 6 and 7. So while an unvaccinated person might pass it on to ~6.7 people you will pass it on to only 4.2 people in the beginning (37% reduction), then to 5.8 people (13% reduction).
This calculation also assumes that your chance of getting Covid is the same as an unvaccinated person, which is not correct.
What interpretation are you expecting people to make? Because there's a huge impact from vaccination.
The chances of having a breakthrough infection and passing it to someone else are quite a lot smaller than the chances of getting infected while being unvaccinated and passing it to someone else, just because breakthrough infections aren't that high (Even if they are higher than we'd like).
