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.

A US senate subcommittee was told this unpublished vaccine study was 'the most important ever.'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:
