Medical experts looking into the Provincetown outbreak of COVID-19 have found the now-dominant delta variant may be able to spread among fully vaccinated people. The good news among the Ptown crowd is there were very few hospitalizations and zero deaths thanks to the majority of those infected having been vaccinated.
From ABC News:
Following multiple large gatherings in Provincetown, Mass., from July 3-17, investigators identified 469 COVID-19 cases, two-thirds of which were in fully vaccinated people. The delta variant was responsible for 90% of those cases.
The breakthrough infections were among people vaccinated with Pfizer, Moderna and Johnson & Johnson. None of the vaccinated people died, but most had some symptoms.
During the outbreak investigation, researchers learned that the amount of virus in the noses of vaccinated people experiencing a breakthrough infection was the same as in an unvaccinated person — a worrying sign vaccinated people can spread the virus.
Experts are finding that the delta variant much more contagious than the initial COVID-19 variants.
Dr. Dan Barouch, director of the Center for Virology and Vaccine Research at Beth Israel Deaconess Medical Center, told ABC News, “The rules have changed. We have a different epidemic now that we did in May.”
Apparently, it was this new data that led the CDC to change its mask policy.
