So @marwilliamson wants to “coordinate and provide direction to the @NIH, the @CDCgov, the @FDACBER of the @US_FDA, the @NCHStats, @NLM_NICHSR, and the @CMSGov in monitoring the need for and the effectiveness and adverse effects of vaccines and immunization activities.” 1/https://twitter.com/annamerlan/status/1203127158433927168 …

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 …

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/Show 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. 16/16Show this thread
