Questions Are Welcome Here: Making Sense of the Latest Vaccine News

Science. Compassion. Conversation.

Monday brought another round of major and understandably confusing headlines about childhood vaccines. On August 10, President Trump signed an executive order directing significant changes to federal childhood vaccine recommendations: narrowing the list of vaccines recommended for all children, calling for immunizations to be given at separate visits rather than together, and calling for the combined measles, mumps and rubella (MMR) vaccine to be split into three separate single-disease shots.

Medical organizations and public-health experts across the country have objected, for a specific reason: no new evidence prompted these changes. Nothing was published, no new safety signal emerged, no study changed what we know. As the president of the American Academy of Pediatrics put it, "There is no new evidence to justify significant changes to childhood immunization guidance."

For parents trying to make good decisions for their children, headlines like these can be unsettling. We want to offer some context and, more importantly, some reassurance.

What actually changes right now?

For families in Oregon, very little changes immediately.

An executive order can direct federal agencies and shape federal policy. It does not instantly rewrite state vaccination requirements, and it does not change what vaccine products exist in a pharmacy's refrigerator.

Oregon's school and child care immunization requirements are set in Oregon administrative rule, at the state level. They do not automatically follow federal recommendations. Oregon Health Authority and the West Coast Health Alliance (which consists of Oregon, Washington, California and Hawaii) continue to endorse the American Academy of Pediatrics' child and adolescent immunization schedule, as they have since the alliance formed.

There is also a practical problem with the proposal to divide MMR into three separate shots: no one can simply separate an MMR vaccine. Individual measles, mumps and rubella vaccines are not available in the United States. Merck stopped producing them in 2009, and the FDA has not approved any single-disease replacements. The vaccine available to practices is the combined MMR, which has been studied and used for decades.

The order itself acknowledges this. It calls for separate shots "once such products are domestically available" which is to say, not now, and not on any announced timeline.

So if you are wondering whether your doctor's office will begin giving three different vaccines instead of MMR tomorrow: the answer is no.

Much of the rest is also unsettled. The order directs a federal task force to deliver implementation plans within 90 days. Some proposals would require manufacturers to develop products that don't currently exist. State recommendations may continue to differ from federal ones. It is genuinely too early to say how much of this will be implemented, and we would rather tell you that honestly than pretend to more certainty than exists.

What the order changes on paper

The order sorts childhood vaccines into three tiers. Measles, mumps, rubella, diphtheria, tetanus, pertussis, polio, Hib, pneumococcal disease, HPV and varicella remain recommended for all children. Others, including hepatitis B, hepatitis A, RSV, meningococcal disease, rotavirus, influenza and COVID-19 move to "high-risk" or "shared clinical decision making" categories.

Some of these are worth a real conversation, and shared decision making is a legitimate model in medicine. Others are harder to explain on the evidence. Universal hepatitis B vaccination beginning at birth, for example, exists precisely because risk-based screening missed infants who went on to develop chronic infection. Narrowing that recommendation is not a neutral administrative change.

If your child's schedule includes any of these, this is a good thing to bring to your next visit rather than something to sort out alone from a news article.

What does the evidence say about separating MMR?

The most important thing to remember is that the scientific evidence about MMR did not change when the policy changed.

The American Academy of Pediatrics notes there is no evidence that giving separate measles, mumps and rubella vaccines is safer than giving the combined MMR. The CDC has said the same: no published scientific evidence supports splitting it.

It's worth knowing where the idea came from. The proposal to split MMR into single shots originated with the 1998 paper that claimed a link between MMR and autism a paper that was retracted, whose findings could not be replicated, and whose author lost his medical license. The proposal never had evidence behind it. It has simply outlived the study that produced it.

The evidence on vaccines and autism has only gotten stronger since. A study following more than 650,000 children, another of 2.5 million, and a 2021 Cochrane review of 138 studies have all found no association. Oregon Health Authority now addresses this misinformation directly in its vaccine guidance.

Delaying vaccines isn't a neutral choice either. The schedule is timed to protect children during the ages when they are most vulnerable to particular infections and that timing is the point, not an administrative convenience. Spreading doses across additional appointments leaves children susceptible for longer and increases the chance that later doses are delayed or missed altogether. CDC data show that giving eligible vaccines at the same visit makes it more likely a child is fully protected on time. Every additional appointment is another appointment that can be missed; because of work, weather, illness, a car that wouldn't start, and or just life.

That is not a criticism of parents. It's a criticism of a policy that quietly makes protection harder to complete while presenting itself as caution without evidence to support it.

Misinformation is hardest when it comes from people we expect to trust

There has always been health misinformation on the internet. What feels different right now is that some inaccurate claims are coming from federal officials.

At the announcement of this executive order, claims were made about the number of vaccines children receive, the safety of combined MMR vaccination, and a link between vaccination and autism. Independent fact checkers and medical experts found several of those statements false or misleading.

The pushback has not fallen along party lines, which we think matters. Senator Bill Cassidy, a Republican and a physician, responded: "I'm a doctor. This executive order is wrong. The President does not have the expertise to make these changes. Vaccines are overwhelmingly safe. Vaccines are effective. Vaccines DO NOT cause autism." The American College of Physicians described a "troubling pattern" of changing vaccine guidance unilaterally rather than through transparent scientific review.

Our concern here is not partisan. It is about process. Public health depends on trust, and trust is hard to sustain when recommendations change without a scientific explanation, or when political messaging gets mixed into medical advice.

But we also don't think the answer is to replace one kind of unquestioning trust with another.

Ask questions.

Ask why a vaccine is recommended. Ask what disease it prevents. Ask about side effects. Ask what the evidence actually shows. Ask what happens if you delay it. Ask whether your child's medical history changes the recommendation.

Those are good questions. They're the same questions we ask.

There is still a broad medical community to turn to

One hopeful part of this moment: physicians and scientists have not stopped doing their work. The American Academy of Pediatrics continues to publish an independent, evidence-based immunization schedule. Oregon and the West Coast Health Alliance have endorsed it. Organizations representing more than a million health professionals have expressed broad agreement about its safety and benefits.

If you're trying to sort credible information from frightening headlines or social-media posts, these are good places to start:

• American Academy of Pediatrics / HealthyChildren.org — particularly helpful for parents, with plain-language explanations of vaccine safety, schedules and common questions.

• Oregon Health Authority — especially useful for Oregon-specific vaccine recommendations, availability and school requirements. Its vaccine-safety pages also link to additional independent scientific resources.

• West Coast Health Alliance — Oregon, Washington, California and Hawaii's collaborative source for evidence-based regional public-health guidance.

• American Academy of Family Physicians — publishes evidence-based immunization guidance for family physicians caring for children and adults.

• World Health Organization — useful for understanding the larger body of international vaccine research and how vaccines are tested and monitored for safety.

• Want to know what each vaccine actually protects against? or What is actually in this vaccine? The Children's Hospital of Philadelphia Vaccine Education Center lets you explore vaccines disease by disease , including what the infection can do, potential complications, how the vaccine works, and vaccine safety information.

And perhaps the most important resource is the person who actually knows you: your family physician, pediatrician or other trusted health professional.

Where we go from here

It would be easy for this moment to make us cynical. We don't think that's where we should go.

Science is not a political party. It's a process: asking questions, studying outcomes, challenging assumptions, reviewing evidence, and changing recommendations when better evidence tells us we should. What troubles us about this order is not that it changed something it's that nothing new was learned first.

And medicine is more than science alone. It is also about relationships.

At Clear Health, we'll keep watching these changes carefully. We'll keep looking to high quality evidence and to trusted professional organizations, including the American Academy of Pediatrics and our public health partners here in Oregon. And when recommendations genuinely need to change because the evidence changes, we'll tell you that too.

Most importantly:

Questions are welcome here.

You do not need to arrive at your doctor's office already knowing everything about vaccines. You don't need to feel embarrassed because you saw something online that worried you. You don't need to have decided anything yet.

Our job is to listen. Our job is to explain the evidence and talk about benefits, risks and uncertainties honestly. We're here to help you make thoughtful decisions for yourself and your family.
