Generously we may call this an oversight that so many in front line medical believe there is no collection method or refuse to use it. Negatively, it provides plausible deniability to high minded academics while the process is intentionally shortcutted at the ground level in a massive fraud and cover up.
For myself, I've personally seen this lack of reporting for years, even before COVID, by nurses and doctors at various hospitals. There is a very pervasive attitude of, the vaccines are safe therefore your problem immediately following is total coincidence and we will report nothing.
Given it's existence for years and the lack of general training in this regard I can't help but lose trust in the entirety of the system as, at best, extremely dysfunctional.
