I’ve written an article for The Conversation about the so-called “Inconvenient Study,” described as a landmark study demonstrating vaccines cause chronic health conditions in children, highlighting its major design flaws and statistical problems that prevent it from showing what its promoters claim

ACIP voted to drop the MMRV combo shot for kids <4 due to seizure risk.
But strangely, they blocked coverage under CMS/private plans while still allowing it under VFC.
No explanation given — even panelists seemed puzzled.
End result: parents lose an option, but only for a random subset of kids.

A US senate subcommittee was told this unpublished vaccine study was 'the most important ever.' Henry Ford Health now confirms why it was never published: it failed scientific standards.
Here's what's actually wrong with the study:
