About the combined MMR and varicella vaccine (MMRV), ACIP has just voted to *not* recommend MMRV before the age of 4 years.
This will not change access to MMR and varicella separately.

A new Nature Medicine study analyzing health records from >100 million people in the US offers compelling evidence that reactivation of varicella-zoster virus (VZV) ,the same virus that causes chickenpox and shingles may contribute to dementia risk.

THIS IS HUGE! Researchers at Stanford University have found that getting vaccinated against shingles- a painful and debilitating condition that can flare up years after infection from varicella zoster virus- not only LOWERS the risk of infection, but can also PROTECT against dementia. 🧪🧵⬇️

This means they are going to restrict access to the MMRV, based on MMR + varicella being available as alternatives.
But they’ll come after MMR and varicella next

Evidence suggests reactivations of the varicella-zoster virus may accelerate aging and raise dementia risk. Now scientists want to know if vaccines and antivirals could help protect the brain.

To be very clear:
ACIP is still recommending BOTH the MMR (measles, mumps, rubella) and Varicella (chickenpox) vaccines, just not the combined MMRV shot.
This is due to a reported increased risk of febrile seizures from the MMRV compared to when the MMR and Varicella are administered as two shots.
