Of course, antivaxxers also love to point to VAERS to make all sorts of ludicrous claims about vaccines having caused deaths, autism, etc. Here’s the thing. Anyone can report anything to VAERS. A VAERS report does NOT indicate causation. 7/

Also, antivaxxers and their attorneys have tainted VAERS with a lot of claims that vaccines caused autism, making it basically useless as anything other than a hypothesis-generating database. 8/https://respectfulinsolence.com/2008/01/18/how-vaccine-litigation-distorts-the-vaer/ …

Let’s just put it this way. If you’re not by a car after receiving a vaccine, that doesn’t mean the vaccine was responsible. 9/

The CDC runs two other databases, both active reporting systems, meaning that the system actively looks for adverse events after vaccination. One is the Vaccine Safety Datalink (VSD). 10/ https://www.cdc.gov/vaccinesafety/ensuringsafety/monitoring/vsd/index.html …

VSD is a collaborative project between CDC’s Immunization Safety Office and 8 health care organizations started in 1990. It’s used to research hypotheses coming from VAERS. 11/ https://www.cdc.gov/vaccinesafety/ensuringsafety/monitoring/vsd/index.html …

Then there’s the Clinical Immunization Safety Assessment (CISA), also run by the CDC. It was established in 2001 to address the unmet vaccine safety clinical research needs, partnered with several academic medical centers and

PRISM is a "a powerful, computer-based system that separates critical bits of information from vast streams of health care data in order to investigate adverse events and determine if there is a connection to a specific vaccine." 14/ https://www.pharmacist.com/article/prism-identifies-vaccine-safety-issues …

Oops. Prematurely hit the “Tweet button.”
In any event, the FDA used PRISM to identify a link between a rotavirus vaccine and an increased risk of intussusception in infants. 15/1 reply 1 retweet 14 likesShow this thread
So, to conclude, @marwilliamson, like all antivaxxers, is utterly clueless about the multiple systems already in existence, one passive, and three active surveillance systems, to monitor vaccine safety in the US, and she just demonstrated it again. 16/16
