@jmc I am not quite sure what you are suggesting here.
Do you think the CDC are seeking to establish this PRR nonsense for all 'vaccines' in future, and that historical standards will be abandoned?
Or are you suggesting that CDC are deliberately carrying the can for the pharma industries in this particular case by adopting this nonsens? If so, CDC is not practising CYA but pulling their own trousers down to save the pharma's backside.
In any case, it should be absolutely clear to even the slow-witted that the PRR assessment is utter nonsense and simply misses the huge death toll and adverse reactions entirely.
Just for SARs Cov2. Its a straight coverup.
Whatever the CDC might have been in decades past the CDC post 2009 bears not the slightest relationship to what they were before. As a reputable scientific organization. By 2012/14 the old CDC was dead in buried.
In 2009 the guy who had totally destroyed the NYC Health Dept reputation for medical excellence was made head of the CDC.
https://en.wikipedia.org/wiki/Tom_Frieden
Staff was increased by 400%. All the experienced middle managers who had serious medical and scientific backgrounds were sidelined or retired. The CDC under Frieden decided that infectious disease in the general population were now unimportant and that "health equity" was all that mattered. In order words "systemic racism" was a bigger health threat than TB or West Nile Virus.
Soon upper management at the CDC was all "health equity" hucksters with little or no actual scientific or clinical experience. So the huge institutional memory of high quality medical and scientific knowledge that they had build up soon walked out the door as all the good researchers went elsewhere. The CDC was just left with the time serving dregs, civil services types, or juniors fresh out of college no nothing grads.
By 2017 there was just a shell left and nothing to be saved. Which is all the CDC is today. A worthless shell.
That why it took the CDC almost 6 weeks to correct sending out the wrong primer / probes for SARs CoV 2 in Feburary 2020. Even though commercial labs offered substitutes within 48 hours of the problem being notified.
So I would put the CDC in the same category as the WHO. A purely political organization who scientific pronouncement should be treated with extreme skepticism.
