*If* we ever get corroboration in the US, it will come from analyzing Medicare data. Unlike the fractured and incomplete records available for vaccinations that were covered by private health insurance -- such as EPIC -- the services and Dx codes for Medicare beneficiaries are all in one place and all uniformly coded.

The problem is -- independent researchers have to have approved data use agreements in place to access Medicare data. And it's HHS that grants those approvals. I'm guessing that the parent organization of CMS, NIH, FDA, and CDC is *not* going to be in a hurry to let those rocks be turned over.
