It would not make a difference whether the infant was contaminated by a vaccinated or unvaccinated person. The bacteria in the infant would act the same.

No it was from a vaccine virus.

The whoop is mostly in a very young child because the trachea is narrow and the air while exhaling makes that sound. Older kids generally don't have a whoop and neither do grow-ups of course.

I don't think it is spread that easily. You have to come in close contact like kissing or cuddling a baby. And anyone can spread the bacteria. You don't have to be coughing.
Even a person who has no cough can spread it if they carry the bacteria.
