Vaccinated People Spread The Delta Variant, CDC Says

[TomK]

The studies actually say the viral loading is about the same for either. 

The one study you cite says:

"Adults who have been fully vaccinated against SARS-CoV-2 can carry the same viral load of the delta variant as those who are unvaccinated, a preliminary analysis of UK data suggests."

I suspect that's the only bit you read or is the only bit you saw on a conspiracy website. What you fail to mention is it's much more unlikely vaccinated people become infected in the first place. We've already discussed this on PW but clearly the message hasn't got through to you. The study you cite goes on to say (bolding is mine):

"The latest results from the UK’s national covid-19 infection survey show that having two vaccine doses remains the most effective way to ensure protection against delta. But, although people who are fully vaccinated have a lower risk of becoming infected, those infected with the delta variant can carry similar virus levels as unvaccinated people, the data show. The authors said the implications for transmission were not yet clear but suggested that the potential for fully vaccinated individuals to transmit the virus to others would make achieving herd immunity more of a challenge.

Sarah Walker, professor of medical statistics and epidemiology at the University of Oxford and chief investigator of the survey, said, “We don’t yet know how much transmission can happen from people who get covid-19 after being vaccinated—for example, they may have high levels of virus for shorter periods of time.

“But the fact that they can have high levels of virus suggests that people who aren’t yet vaccinated may not be as protected from the delta variant as we hoped. This means it is essential for as many people as possible to get vaccinated—both in the UK and worldwide.”"

I wish an infographic could be produced that shows how many people were infected with COVID from unvaccinated people.  I suspect it would be rather telling.
