During the Trump administration, the left demanded the most rigorous of clinical trials and controls before any possible treatment that the right – and Trump in particular – might have suggested was possibly helpful in fighting COVID. And yet this is the situation today:
The nation’s top infectious disease expert [Fauci] says the Indian ‘Delta’ Covid variant has the same viral levels in vaccinated people who have breakthrough infections as in those who are unvaccinated…
But the CDC has yet to publicly share new research on Delta transmission among the vaccinated that would back up its new mask guidance and outside experts are calling for the agency to show them the data.
Data? You don’t need no steenking data from us. We’re the CDC! We’ll show it to you someday:
A citation in the updated masking guidance simply reads, ‘CDC COVID-19 Response Team, unpublished data, 2021.’
These data come from investigations of recent Delta-caused outbreaks, in which researchers compared infections among vaccinated and unvaccinated people, according to the Washington Post.
The findings will be ‘published imminently’ per reporting from The Post.
Some scientists – actual, bona fide scientists – would like to check it out rather than take it on faith:
They’re making a claim that people with delta who are vaccinated and unvaccinated have similar levels of viral load, but nobody knows what that means,’ Dr Gregg Gonsalves, an associate professor at the Yale School of Public Health, told The Post.
‘It’s meaningless unless we see the data.’
Other experts aren’t convinced that a higher viral load actually leads to Delta’s transmission among vaccinated people.
There’s a whole chain of assumptions here by the CDC. The first is that the CDC’s data, whatever it is, holds up and that with the Delta strain the vaccinated and unvaccinated who get COVID have the same viral load. The second is that with Delta the nasal viral load really does reliably determine transmissibility, and that this means that both groups are equally likely to spread the disease to others. The third is that masking would significantly protect from such spreading with Delta. The fourth is that the Delta variant will cause a rise in serious cases and deaths and not just in cases and/or positive test results. The fifth is that there are a very significant number of breakthrough COVID cases in the vaccinated in this country, enough to justify requiring their masking.
I’m probably leaving out a few assumptions, but you get the idea.

‘I feel like nasal viral load is one part of a lot of other parts’ that determine how infectious a person is, biostatistician Natalie Dean told The Post.
Dean added that she thinks other important factors may be how much virus is present in a patient’s throat or lungs…
…[T]he CDC is not tracking less-severe breakthrough infections. In May, the agency switched its strategy to only investigate and report those infections that cause hospitalization or death
Scientists have critiqued this move for leaving the U.S. without crucial data to monitor the cases caused by Delta and other variants.
Apparently this recent “masks even for the vaccinated” proclamation was also based on a study from India that was initially rejected by a Nature Portfolio Journal and is currently out for “revision”:
The study in question from researchers in India analyzed vaccine breakthrough in over 100 healthcare workers and claims to show that a COVID-19 Delta variant infection generates a higher viral load in comparison to other variants.
Despite no mention in the study of viral loads from the variant against unvaccinated individuals, the CDC cited it in yesterday’s updated brief as evidence that the Delta variant is transmissible from a vaccinated individual with a breakthrough infection.
This study does not compare vaccinated viral loads to unvaccinated viral loads; it compares Delta viral loads to viral loads in other variants and finds them to be higher. And the vaccination involved in India is AstraZeneca, not used in the US and known to be less effective against COVID than Pfizer and Moderna, which are used here. In addition, the abstract to the article says that “severe disease in fully vaccinated HCW [health care workers] was rare.” So, even if ultimately approved for publication, the relevance of this article to the situation here is highly suspect.
I can’t say exactly where I think the threshold should lie for a recommendation for restrictions like this, but I can say that I don’t think it has been met in this case at all. And on these slender reeds they base a recommendation for the vaccinated to mask up in places experiencing an upswing. Not only that, but a lot of people are taking this to mean that vaccines “don’t work,” which discourages vaccination rather than encouraging it.
What’s going on? Is it just that the authorities are in love with the sound of their own authoritative voices, addicted to restricting liberty and to telling people what to do? And to feeling oh-so-virtuous as they make their proclamations and get people accustomed to the habit of obedience? I think it’s at least partly that. But I think another reason is that they are terrified that the numbers will go up under their watch, and that it will have negative political repercussions for their side. Of course, all this back and forth, masking and unmasking and masking again, will almost certainly have negative political repercussions for them, too.
