An outbreak in Provincetown, Massachusetts—in which 74 percent of the 469 cases were in the fully vaccinated—forced the CDC to update its mask guidance and issue a sad and sobering warning: Vaccinated people infected with the SARS-CoV-2 Delta variant can be just as contagious as unvaccinated people.

In the aftermath of the Provincetown announcement, many who had gotten their shots were confused about what the news meant for them, especially when headlines seemed to imply that vaccinated individuals are as likely to contract and transmit COVID-19 as the unvaccinated. But this framing missed the single most important factor in spreading the coronavirus: To spread the coronavirus, you have to have the coronavirus. And vaccinated people are far less likely to have the coronavirus—period. If this was mentioned at all, it was treated as an afterthought.

Despite concern about waning immunity, vaccines provide the best protection against infection. And if someone isn’t infected, they can’t spread the coronavirus. It’s truly that simple. Additionally, for those instances of a vaccinated person getting a breakthrough case, yes, they can be as infectious as an unvaccinated person. But they are likely contagious for a shorter period of time when compared with the unvaccinated, and they may harbor less infectious virus overall.

Additionally, it mentions that +96% of recent cases from NYC were unvaccinated, .33% fully vaxxed.
