In a stunning development, the Centers for Disease Control and Prevention (CDC) last week admitted — despite assurances to the contrary — the agency never analyzed the Vaccine Adverse Event Reporting System (VAERS) for safety signals for COVID-19 vaccines.
The admission was revealed in response to a Freedom of Information Act (FOIA) request submitted by Children’s Health Defense (CHD).
The signals were loud and clear, leading me to wonder “why is nobody listening?”
Instead, I should have asked, “Is anybody even looking for them?”
Since CDC officials stated publicly that “COVID-19 vaccine safety monitoring is the most robust in U.S. history,” I had assumed that at the very least, CDC officials were monitoring VAERS using the methods they described in a briefing document posted on the CDC website in January 2021 (and updated in February 2022, with minor changes).
I was wrong.
The lynchpin of their safety monitoring was to mine VAERS data for safety signals by calculating what are known as proportional reporting ratios (PRR’s).
This is a method of comparing the proportion of different types of adverse events reported for a new vaccine to the proportion of those events reported for an older, established vaccine.
If the new vaccine shows a significantly higher reporting rate of a particular adverse event relative to the old one, it counts as a safety signal that should then trigger a more thorough investigation.
The briefing document states, “CDC will perform PRR data mining on a weekly basis or as needed.”
