Never had that happen. Say what you will about most Federal agencies (and I am likely to agree with you) but the CDC is one of the cleanest, least-sullied agencies out there.
Well, except for tobacco. They have a hard-on for tobacco. :)
OK in most of the government, it’s pretty routine for employees to get politically-driven orders that are at complete odds with reality.
When that happens, the CYA instinct kicks in (those who don’t have it, don’t last long in government employment). So they produce the report in such a way that the requester gets something that appears to be what they want, while not leaving the employee on the hook for how it is used.
This is a textbook example of that phenomenon. Enough verbiage to make a middle manager’s eyes glaze over so that they don’t realize that they didn’t really get what they wanted.
CDC is sooo clean, I suppose you have never heard of Dr. William Thompson? or the movie Vaxxed??
Here’s a little info for you, “The scientist, Dr. William Thompson, confessed that the CDC had omitted crucial data in their final report that revealed a causal relationship between the MMR vaccine and autism. Over several months, Dr. Hooker records the phone calls made to him by Dr. Thompson who provides the confidential data destroyed by his colleagues at the CDC.”
Here’s a link to the movie info, http://vaxxedthemovie.com/
