Earlier this week we posted
1. The CDC web site says that it is very rare for a vaccinated person to get infected and transmit the virus.
2. Fauci opined a similar view in a CNBC interview but backed down when confronted with some compelling anecdotal evidence and a dearth of CDC data to the contrary.
3. CDC Director Walensky told CNN that we should expect “tens of thousands of breakthrough infections and hundreds of thousands of daily cases.”
How to square this circle of opinions?
Let’s go back to the beginning…
=============
The Vax Companies
When the vax companies applied for Emergency Use Authorizations, they presented clinical trial results that evidenced 90% or better protection against symptomatic infections.
But, the companies were silent on protection against asymptomatic infections (now estimated as about 3 in 4 covid infections).
The simple reason: Their clinical trials didn’t measure asymptomatic infections.
So, little could be inferred from the data regarding transmission.
Perhaps the vax companies should have been even more loudly explicit about the limitations on their claims.
Why?
Because their silence provided misinformers a window of opportunity to, well, misinform.
==============
The Misinformers
Case in point: MSNBC’s Rachel Maddow — the font of truth for roughly half of the country.
Earlier this year, Maddow ironically — in a characteristic rant about misinformation — preached to her devotees that “you are like 90% less likely to get infected and transmit to anybody else” … so get vaxxed or you might kill somebody.
Again, keep in mind that the clinical studies didn’t track asymptomatic infections … the 90% applied only to symptomatic (and test confirmed) cases.

Maddow’s view was totally unsupported by any data … but, it was emotionally supportive of the pro-vaccine narrative and caught on with other left-leaning amateur-scientific-influencers … who probably didn’t read the vax companies’ EUA applications or fret over the lack of supporting data.
Bottom line: Maddow’s admonition, albeit factless at the time, was compelling and contagious.

Fauci
Apparently, Fauci bought into Maddow’s riff until CNBC’s Sarah Eisen asked for the data and he had to admit that the data was limited since the CDC hadn’t been doing surveillance studies to track asymptomatic infections..

CDC Director Walensky
Walensky — while likely unaware of what the CDC was pitching on its web site — is probably trying to walk back to the more realistic view that the vaccines are highly effective … but their promised efficacy is limited to symptomatic and severe infections. … and that the total effectiveness against infections (including asymptomatic infections) wanes over time.
