CDC has tainted epidemiological data by issuing guidance to exempt vaccinated people from testing unless symptomatic. Vaccinated asymptomatic cases were simply not counted for a period of time ending in late June 2021. I can't find the date when they issued the faulty guidance for a precise time interval, but any study comparing vaccinated / unvaccinated cases relying on US epidemiological data including May/June 2021 must sadly be considered tainted.

However, it's worth emphasizing that none of that invalidates the parent commenter's claim that vaccination provides significant additional protection against reinfection for people who've already had COVID, as the study linked in the press release finds.
