Montana pediatrician group pushes back against CDC vaccine changes

On Monday, Jan. 5, the Centers for Disease Control and Prevention announced it would downgrade six vaccines on the routine schedule for childhood immunizations. The changes scale back recommendations for hepatitis A and B, influenza, rotavirus, RSV and meningococcal disease. 

That decision — shared by top officials at the federal Department of Health and Human Services — took many public health experts by surprise, in part because of how the administration of President Donald Trump departed from the CDC’s typical process for changing childhood vaccine recommendations. 

Montana Free Press spoke to Atty Moriarty, a Missoula-based pediatrician and president of the Montana Chapter of the American Academy of Pediatrics, about her perspective on the CDC’s changes. The interview has been edited for length and clarity.

MTFP: What happened in this most recent change and how does that differ from the CDC’s normal process for adjusting childhood vaccination schedules?

Moriarty: The way that vaccines have traditionally been recommended in the past is that vaccines were developed, and then they traditionally went through a formal vetting process before going to the [CDC]’s Advisory Committee on Immunization Practices, or ACIP, which did a full review of the safety data, the efficacy data, and then made recommendations based on that. Since November 2025, that committee has completely been changed and is not a panel of experts, but it is a panel of political appointees that don’t have expertise in public health, let alone infectious disease or immunology. So now, this decision was made purely based unilaterally on opinion and not on any new data or evidence-based medicine. 

MTFP: Can you walk through some of the administration’s stated reasons for these changes?

Moriarty: To be honest, these changes are so nonsensical that it’s really hard. There’s a lot of concern in the new administration and in the Department of Health and Human Services and the CDC that we are giving too many immunizations. That, again, is not based on any kind of data or science. And there’s a lot of publicity surrounding the number of vaccines as compared to 30 years ago, and questioning why we give so many. The answer to that is fairly simple. It’s because science has evolved enough that we actually can prevent more diseases. Now, some comparisons have been made to other countries, specifically Denmark, that do not give as many vaccines, but also are a completely different public health landscape and population than the United States and have a completely different public health system in general than we do.

MTFP: Where is the American Academy of Pediatrics [AAP] getting its guidance from now, if not ACIP?

Moriarty: We really started to separate with the [CDC’s] vaccine recommendations earlier in 2025. So as soon as they stopped recommending the COVID vaccine, that’s when [AAP] published our vaccine schedule that we have published for the last 45 years, but it’s the first time that it differed from the CDC’s. We continue to advocate for immunizations as a public health measure for families and kids, and are using the previous immunization schedule. And that schedule can be found on the [AAP’s] healthychildren.org website.

MTFP: Do any of the recent vaccine scheduling changes concern you more than others?

Moriarty: I think that any pediatrician will tell you that 20-30 years ago, hospitals were completely full of babies with rotavirus infection. That is an infection that is a gastrointestinal disease and causes severe dehydration in babies. I’m nervous about that coming roaring back because babies die of dehydration. It’s one of the top reasons they’re admitted to the hospital. I’m nervous about their recommendation against the flu vaccine. [The U.S. is] in one of the worst flu outbreaks we’ve ever seen currently right now and have had many children die already this season. 

MTFP: Do you think, though, that hearing this changed guidance from the Trump administration will change some families’ minds about what vaccines they’ll elect to get for their children?

Moriarty: Oh, absolutely. We saw that before this recommendation. I mean, social media is such a scary place to get medical information, and [listening to] talking heads on the news is just really not an effective way to find medical information, but we see people getting it all the time. I meet families in the hospital that make decisions for their kids based on TikTok. So I think that one of the effects of this is going to be to sow more distrust in the public health infrastructure that we have in the United States that has kept our country healthy.
