Day1 they voted it wood maintain coverage of mmrv and day 2 they revised that decision. The decision re hepb which had been almost decided d1 was pushed to a later meeting. This meeting was an utter shambles

They also reversed an action from the prior meeting regarding whether Vaccines for Children, a US government program that provides free vaccines to low-income children would cover the MMRV vaccine

With advice suggested to be different for different age groups and risks of vaccines even if v rare raised. Some states will require prescriptions if not a vulnerable group and some not. Basically it’s v confusing!

Covid vaccines now available as part of ‘individual-based decision making and ‘shared clinical decision making’ that were used interchangeably despite not being quite the same thing

Kennedy’s inexperienced and under-qualified ACIP continues to make a mockery of science based evidence with confusion regarding what they were voting for, actions such as changing votes, pushing other votes down the line, use of anecdotes versus science and ambiguous decisions…🧵

The change in MMRV recommendation was made based upon their opinion regarding risk of vaccines not upon the published science or risk of the viruses

Important study (that rather flies in the face of recent vaccine decisions) that considers the risk of Covid (and long Covid) on the cardiovascular system and the need to note and rehabilitation to better manage CV symptoms. Also suggest vaccines are an important tool to prevent such complications

He hasn’t finished- the hepb votes are today and so are discussion on covid and flu vaccines and this is just the start. In just a few months he has eroded trust in science, vaccines and damaged vaccine access
Prof Sheena Cruickshank (@sheencr.bsky.social) reply parent
This was ALL too predictable based upon the fact that ACIP are handpicked by Kennedy and he has been signaling his likely initial targets. This will impact vaccine uptake as puts barriers up for easy access to vaccines requiring more appointments and we know this puts people off

The 2nd change looks at hepatitis B vaccines which given at birth- this looks to be removed until at least 6 months from lower risk babies - this may sound reasonable but not all mums get screened & a lot depends upon quality of pre-natal care which very variable & newborns vv vulnerable to HepB
Prof Sheena Cruickshank (@sheencr.bsky.social) reply parent
The reason for change to the all in one given as they used an anti-vax tactic of inflating risk of vaccine whilst not discussing relative risk of viruses - there is a small risk of a transient fever seizure from vax but that risk is over 1000 times greater from viral infection.
Prof Sheena Cruickshank (@sheencr.bsky.social)
As expected, ACIP have voted through big changes to childhood vaccines schedule with more actions slated today. Firstly, no more combined MMRV - (mumps measles rubella chickenpox) for first dose- instead MMR and chickenpox to be given separately but option for 2nd dose & the combined shot remains 🧪🧵

A couple thoughts as a reporter who's been covering RFK Jr and watched today's hearing with fired CDC director Susan Monarez 1) the biggest things I heard today were about the CDC's childhood vaccine schedule. Monarez testified that RFK Jr told her he talks to Trump "every day" about changing it.
Prof Sheena Cruickshank (@sheencr.bsky.social) reply parent
However anti-vaxers have used vaers as a tool to make spurious allegations about vaccines and now RFKJr is looking to weaponise it which could have massive repercussions for vaccine access.

So it gets a LOT of noise of random or made up events (sorry don’t believe the Incredible Hulk claim) but it’s important because independent researchers look for common themes and signals so they can identify REAL adverse events

However this places many in a lottery where access depends on where you live or what you can afford. Meanwhile the next ACIP meeting is looming with its focus on childhood vaccines and eg hepb vaccines all of which RFKJr has often spoken against

Vaccine access for covid reduced despite RFKJr claiming that anyone can get them as without recommendation for eg pregnant people, not all doctors and pharmacists or all insurers incl Medicaid will cover them. Fortunately some democrat states washing access by state actions

Notably the Project 2025 conservative roadmap for the new Trump administration did state it would strip the CDC of its ability to issue guidance on vaccines and to end required testing for new pathogens. This is clearly happening including scaled back food borne pathogen testing
