But Dr Phelps pointed to data from Germany’s pharmacovigilance body, the Paul Ehrlich Institute (PEI), which has “undertaken ongoing surveys of vaccine recipients … as opposed to the TGA which only accepts passive reports, or AusVaxSafety whose survey stopped at six weeks”. “They have found that the incidence of serious reactions occurs in 0.3 per 1000 shots (not people),” she said. “Considering that the majority of Australian adults have now had at least one booster, this suggests that the incidence of serious adverse reactions per vaccinated person could be more than 1-in-1000. PEI admits that under-reporting is a problem, and observers suggest that an order of magnitude of under-reporting is not unreasonable to consider (most estimates put underreporting at much worse than this).”
