Wash Post: "‘The war has changed’: Internal CDC document urges new messaging, warns delta infections likely more severe"

Many posts here have been saying how easily transmitted the Delta variant is and how vaccinated people can get breakthrough infections and probably infect others as well. This article seems to validate those claims, though a lot of the article is about the CDC struggling with how to communicate what they are finding:

It cites a combination of recently obtained, still-unpublished data from outbreak investigations and outside studies showing that vaccinated individuals infected with delta may be able to transmit the virus as easily as those who are unvaccinated. Vaccinated people infected with delta have measurable viral loads similar to those who are unvaccinated and infected with the variant.

One of the slides states that there is a higher risk among older age groups for hospitalization and death relative to younger people, regardless of vaccination status. Another estimates that there are 35,000 symptomatic infections per week among 162 million vaccinated Americans.

“Although it’s rare, we believe that at an individual level, vaccinated people may spread the virus, which is why we updated our recommendation,” according to the federal health official, who spoke on the condition of anonymity because they were not authorized to speak publicly. “Waiting even days to publish the data could result in needless suffering and as public health professionals we cannot accept that.”

The CDC’s revised mask guidance stops short of what the internal document calls for. “Given higher transmissibility and current vaccine coverage, universal masking is essential to reduce transmission of the Delta variant,” it states.

The document makes clear that vaccination provides substantial protection against the virus. But it also states that the CDC must “improve communications around individual risk among [the] vaccinated” because that risk depends on a host of factors, including age and whether someone has a compromised immune system.

The document includes CDC data from studies showing that the vaccines are not as effective in immunocompromised patients and nursing home residents, raising the possibility that some at-risk individuals will need an additional vaccine dose.

“I think the central issue is that vaccinated people are probably involved to a substantial extent in the transmission of delta,” Jeffrey Shaman, a Columbia University epidemiologist, wrote in an email after reviewing the CDC slides. “In some sense, vaccination is now about personal protection — protecting oneself against severe disease. Herd immunity is not relevant as we are seeing plenty of evidence of repeat and breakthrough infections.”

Kathleen Neuzil, a vaccine expert at the University of Maryland School of Medicine, said getting more people vaccinated remains the priority, but the public may also have to change its relationship to a virus almost certain to be with humanity for the foreseeable future.

“We really need to shift toward a goal of preventing serious disease and disability and medical consequences, and not worry about every virus detected in somebody’s nose,” Neuzil said. “It’s hard to do, but I think we have to become comfortable with coronavirus not going away.”

Unfortunately, many people are probably losing trust in the CDC because their recommendations are changing so often - not appreciating that the scientists there can only make their best recommendations on the solid data they have and the data is constantly changing, especially as the virus changes.

As a side note I'd like to mention that I saw Fauci a couple of days ago on a news show say that the reason vaccinated people have such large viral loads but not get as sick is because the vaccines help the lungs fight off the virus much more effectively than they do in the nose and mouth areas - the nose and mouth areas being the regions where the virus is mostly spread from person to person.

There seems to be a more basic misunderstanding of the public when it comes to science. They think that because the CDC or doctors or scientists or whoever changes their recommendations, that this means they don't know what they're talking about and/or can't be trusted. The reality is that science should be self-correcting and it's an essential feature of science that the understanding of things will and should change, based on learning new information.

This is a VERY new virus, and there's no way that we have come at all close to understanding all the features or aspects of the virus. It should be viewed as normal, good even, that we change what we do as we continue to learn more about the virus and how it works. (For example, I heard one very well-known TV doc claim not too long ago that there's no genetic basis for why some people are harder hit with the virus than others... I don't think that's correct, but the data will eventually demonstrate it one way or the other.)
