Did the CDC Dismantle the VSD to Keep Data Away from RFK Jr?
It should not be a surprise that anti-vaccine influencers see conspiracies everywhere.
Why do some people think that the CDC has dismantled the VSD to keep data away from RFK Jr?
The usual suspects…
Did the CDC Dismantle the VSD to Keep Data Away from RFK Jr?
In this case, Aaron Siri is telling folks that the CDC has given back all the data from the Vaccine Safety Datalink (VSD) to the organizations that collected it.

Data that the CDC doesn’t actually own.
“The DDM allows each MCO to assemble and maintain its computerized data files on a secure server at the site rather than transferring data to the CDC, and ownership of the data is retained by the MCOs. Data required for specific VSD studies are transferred between the CDC and the VSD sites by using 2 secure methods known as the “indirect” and “direct” methods.”

Data that the CDC doesn’t even keep!
Data that Aaron Siri wanted to use to investigate the causes of autism and to do a study on vaccinated vs. unvaccinated kids.
“The VSD uses electronic health record data from member sites to assess vaccine safety and detect adverse events in near-real time.”

And while they often allow researchers to use the data, there is a very good reason that they might not let RFK Jr’s researchers near the data!
“ASAN is gravely concerned by Health and Human Services (HHS) Secretary Robert F. Kennedy Jr.’s (RFK Jr.) reported plans to establish a “registry” of autistic people and to hand over sensitive medical data about autistic people to unnamed researchers, likely without their consent.”

David Geier had already been warned about misusing the Vaccine Safety Datalink database, with actions that could have created the possibility for a breach in patient confidentiality!
Today in a cabinet meeting, HHS Secretary Robert F. Kennedy Jr. promised that “by September, we will know what has caused the autism epidemic and we will be able to eliminate those exposures.” This alarming claim is untrue, impossible, and ableist.

Plus, many people think that with his promise of quick results, in just five months, they already know what the results will be of their studies.
They will “cook the books” and find a way to prove that vaccines are bad.
Hopefully, not being allowed to abuse the VSD will slow them down…

The sight of RFK jr causes me to fly into a rage. He’s a sociopath.
