BMJ Investigation: US Officials Sidelined Warnings on Flawed Vaccine Safety Algorithm
A BMJ probe finds the FDA and CDC knowingly relied on a compromised signal-detection method for COVID-19 vaccine harms and dismissed a doctor who flagged the flaws.
What to know
- A BMJ investigation alleges the FDA and CDC knowingly relied on a compromised algorithm to detect safety signals from mRNA COVID-19 vaccines.
- An FDA doctor who raised concerns about the algorithm's flaws was reportedly sidelined rather than heeded.
- The flawed system may have delayed detection of some vaccine adverse events, according to the investigation.
- The findings have drawn expert reaction and wide social media amplification but no detailed public response yet from FDA or CDC in the provided material.
