Right now, there's a lot of talk about the future of certain vaccines, including COVID-19.
An influential federal advisory group has been meeting and making changes including to the childhood vaccination schedule.
Some doctors worry the moves could put some kids' health at risk.
On Friday, the CDC's revamped Vaccine Advisory Panel debated various recommendations for COVID vaccines.
They just narrowly denied a proposal that states and communities should require a prescription to get a COVID vaccine.
Some worry it would limit access and increase costs, while others say it could lead to important conversations between patients and providers.
On Thursday, the committee voted on a combination shot to prevent measles, mumps, rubella and chickenpox.
That is now not recommended for kids under age four.
Instead, they would get two shots - one for MMR and one for chickenpox to help avoid what is reported to be a slightly increased risk of temporary seizures caused by fever.
A local doctor tells us the combination vaccine is safe.
"The problem with splitting it up is that some parents may not want to get one, and obviously we have to respect choice, but they may not, they may decide not to get one or the other at that point. And so what you're doing is you're losing protection just by splitting it up," Dr. Ulysses Wu, Hartford HealthCare's chief epidemiologist, said.
The recommendations from the panel are not final and still need sign off from the acting CDC director.
Now the panel's vote about a new recommendation for the Hepatitis B shot for infants was delayed.
Amid all of this, Connecticut just announced it had joined six other states in the Northeast to form a coalition on health policy.
We're told the goal is to promote evidence-based public health.
"Our public health team has been working with all of the neighboring states in the Northeast going back to COVID because there was so much misinformation coming out of Washington. We wanted to be clear during COVID. We're back together speaking with one voice when it comes to vaccines," Gov. Ned Lamont (D - Connecticut) said.
And it comes after major shakeups at the CDC, including the decision to remove and replace all the members of the vaccine committee.
Critics are concerned that many of the new members have expressed skepticism about the safety and efficacy of vaccines.
"They criticize us very severely saying we are dangerous and unscientific which is completely false. There's a lot of expertise on this committee," Martin Kulldorff, the vaccine panel chair, said.
