It's official: Vaccinated people don't transmit COVID-19 https://fortune.com/2021/04/01/its-official-vaccinated-peopl...
> "Our data from the CDC today suggests that vaccinated people do not carry the virus, don't get sick, and that it's not just in the clinical trials but it's also in real-world data," CDC Director Dr. Rochelle Walensky told Rachel Maddow on Monday, March 29.
Evidence changes with experience and time.
Evidence is subject to errors in method and interpretation. With luck, those are also corrected with time.
What science does not do is choose some ideologically convenient belief, then selectively cherry-pick and selectively ignore evidence or arguments to buttress that.
At the very top of the article you link is this note:
Since CDC Director Rochelle Walensky made the comments discussed below, scientists have pushed back against the idea that vaccinated people “don’t carry the virus.” We've published a deeper analysis of the debate here.
That is: there is disagreement over the evidence.
The upshot of the announcement, in April of 2021, was this:
[T]he most important part of the recent CDC findings is that vaccinated people are very unlikely to suffer asymptomatic SARS-CoV-2 infections. Participants in the study who were fully vaccinated with the Pfizer-BioNTech or Moderna vaccines were 90% less likely to be infected with SARS-CoV-2. Of infections that did occur, only 10.7 percent were asymptomatic. Taken together, this means vaccinated people are highly unlikely to transmit the virus when they are not suffering symptoms. This also means that as vaccination rates continue to rise, the virus will have fewer and fewer possible hosts.
Again, highlighted at the very top of the article you've selected to link here.
You've chosen to highlight the headline, which was not selected by the CDC and may well not have been selected by the authors either. (Traditional practice is that headlines are written by a headlines editor, more recently, headlines are often selected by A/B testing for impact, clicks, and engagement.)
Moreover, the point made gets to another complaint that's been raised repeatedly by the antiempirical crowd: why should vaccinated people need to wear masks if vaccines protect against transmitting or receiving the virus?
What we've learned since this announcement and piece is that even if vaccinated there remain both transmission and infection risks. Vaccines are not some majickal warding spell, but are simply a technological tool that leverages the body's own immune defences. Sometimes more effectively than others.
And I very strongly suspect that you either know all of this, or have chosen deliberately not to based on your submission and comment history.
Intramuscular vaccines do not do much to prevent replication of proteins in your nasal cavities, where as nasally adminsitered vaccines do much more so. So by population vaccinating people with intramuscular vaccines, we have reduced harm significantly, but we have not meaningfully affected the virus ability to spread.
