CDC Says Delta Variant May Cause Mild but Contagious COVID-19 in Vaccinated People

Headline Roundup July 30th, 2021

Data released Friday by the Centers for Disease Control and Prevention (CDC) suggests that vaccinated people, if infected with a "breakthrough" case of the COVID-19 Delta variant, may transmit it just as easily unvaccinated people. The report says 74% of 469 COVID-19 cases connected to large gatherings held in Barnstable County, Mass., around the July 4 holiday were among fully vaccinated people. Breakthrough COVID-19 cases are rare and typically mild or asymptomatic. According to the CDC, the data served as evidence for its return to recommending that vaccinated people wear masks when indoors in high-transmission regions.

The news made headlines across the spectrum Friday. Some right-rated sources framed the announcement as overdue; many right-rated voices have said the CDC's new masking guidance lacks evidence.

In yet another unexpected and unwelcome twist in the pandemic, fully immunized people with so-called breakthrough infections of the Delta variant may spread the virus to others just as easily as unvaccinated people, the Centers for Disease Control and Prevention said in a report published on Friday.

The vaccines remain powerfully effective against severe illness and death, and infections in vaccinated people are thought to be comparatively rare. But the revelation follows a series of other findings this week about the Delta variant, all of which have upended scientists’ understanding of the...

About 74% of 469 COVID-19 cases associated with large gatherings held in Barnstable County, Mass., from July 3 to 17 were among fully vaccinated people, according to data released Friday from the Centers for Disease Control and Prevention.

Why it matters: The data bolsters emerging evidence that vaccinated people have high viral loads and may transmit the Delta variant as easily as those who are unvaccinated.

Be smart: Despite mild breakthrough cases appearing more common than previously thought, "vaccination is the most important strategy to prevent severe illness and death," the report emphasizes....

The Centers for Disease Control and Prevention (CDC) released a report Friday detailing a recent COVID-19 outbreak in Provincetown, Massachusetts, which was cited by the agency as a contributing factor to its recent change in mask guidance.

Over the July 4 weekend, gatherings in Provincetown contributed to at least 900 cases, and roughly 75% of those who tested positive in the cluster were vaccinated. The Provincetown report concludes that spread among highly-vaccinated populations does occur and suggests that authorities reimplement mask mandates and other mitigation measures, even for the vaccinated.
