Most COVID-19 cases in Massachusetts outbreak among
vaccinated, says CDC




Three quarters of people infected with SLOTXO COVID-19 at public events in
a Massachusetts town were fully vaccinated, a study by the US Centers for Disease
Control and Prevention (CDC) showed.

The study, published on Friday without naming the town, suggested the Delta variant
of the virus was highly contagious.

The study found vaccinated individuals had a similar amount of virus presence as
the unvaccinated, suggesting that, unlike with other variants, vaccinated people
infected with the Delta variant could transmit the virus, the CDC said.

CDC Director Rochelle Walensky said this was a "pivotal discovery" leading to CDC's
recommendation this week that masks be worn in areas where cases were surging
as a precaution against possible transmission by fully vaccinated people.

"The masking recommendation was updated to ensure the vaccinated public would
not unknowingly transmit virus to others, including their unvaccinated or
immunocompromised loved ones," Walensky said.

Overall, 79% of the vaccinated individuals who were infected with COVID-19 also
reported symptoms such as cough, headache, sore throat and fever. Four had to be
hospitalized.

Vaccinated individuals had received one of the three available shots made by Pfizer
and BioNTech, Moderna or Johnson & Johnson, the data showed.

A separate CDC internal document, first reported by the Washington Post, described
the Delta variant as being as transmissible as chickenpox and cautioned it could
cause severe disease.
