@JamesBa73671170 No need. Such systems—yes, *systems*—already exist and have existed for a long time. Contrary to antivax messaging, #VAERS is not the be-all and end-all of vaccine safety monitoring. It has a role as an early warning and hypothesis generating system.
@JamesBa73671170 #VAERS cannot demonstrate causation, nor can it even reliably demonstrate correlation, given how it can be gamed. It can, however, generate hypotheses that other more rigorous existing pharmacovigilance systems (e.g., VSD, PRISM) can be used to test.
@JamesBa73671170 Antivaxxers love to point to #VAERS as if it were the *only* vaccine safety monitoring system because it so easily produces false positive correlations between vaccines and adverse events. They ignore the other active surveillance systems that don’t have the flaws of VAERS.
