Yet, this infectiousness protection starts diminishing for patients
two months post vaccination and ultimately vanishes for patients
6 months or longer post vaccination.

As the Delta variant happened to appear when a large fraction of
the vaccinated population was already past the initial 2 months
post-vaccination, the population-wide average effect of the vaccine
on Delta is negligible, consistent with and explaining reports of
no difference in Ct between vaccinated and unvaccinated infected with Delta.
