Opinion | I’m an Immunologist. I Grew Up Unvaccinated.

Parents’ vaccine decisions are rarely just about evidence. They’re shaped by fear, identity, experience, and love.

A beautiful @nytimes.com piece by my colleague captures that complexity with real empathy. This is a must-read!

New essay out in Community Immunity.

It begins with a simple thought experiment: what if future leaders attempt to restore vaccine policy structures overnight? Would that rebuild trust β€” or deepen polarization?

The way things were isn’t the way things can be anymore.

The AAP releases its 2026 immunization schedule. Now comes the harder part. The AAP’s 2026 immunization schedule is out. What comes next is harder: helping families navigate confusion and conflicting guidance with trust and clarity.

In an information environment that feels chaotic, that steady guidance matters more than ever.

When it comes to vaccines, what parents want has not changed.

They want clear recommendations and honest explanations. They want reassurance that the advice they receive is grounded in their child’s best interest. And they want a trusted expert to help them navigate the noise.

Poll: Trust and Confidence in the CDC Remain at Low Point After Changes to Recommended Childhood Vaccines; More Say the Changes Will Hurt than Help Children’s Health | KFF In the weeks after the Trump administration reduced the number of recommended childhood vaccines for routine use, the public’s trust in the CDC remains at its lowest point. Among those who have heard ...

Who do parents trust? Their child’s pediatrician. More than any federal agency, political figure, or influencer.

Policy should strengthen that trusted relationship, not undermine it.

You don’t rebuild trust with sudden, unjustified changes to evidence-based guidance. You rebuild it through consistency, transparency, and credible scientific processes.

The predictable result of this approach is fewer children vaccinated and more preventable harm. It really is that simple.

This year, trust in CDC vaccine guidance has fallen sharply to its lowest point in years.

People who have heard of recent changes to the childhood vaccination schedule are twice as likely to say the changes will have a negative impact on kids than a positive one.

New KFF data show trust in the CDC as a source of reliable vaccine information is now at a historic low following a recent overhaul to childhood vaccine recommendations.

That matters because federal health leaders have explicitly justified their policy changes as necessary to restore public trust.🧡

Do pediatricians make large profits from vaccines? Vaccine critics like to say that pediatricians profit from vaccines. This report found something very different.

Our article is out today in @statnews.com. Do pediatricians get rich from vaccines? We followed the money. Short answer: ABSOLUTELY NOT. This dangerously misleading claim just won’t die.

The Problem With Calling the U.S. an Outlier on Vaccines And why a little-known commission, a severe flu season, and a hepatitis B vaccine study in Africa deserve attention

New πŸ“° The U.S. is being called a vaccine β€œoutlier.” But why is that assumed to be bad?

Also: changes to a key federal advisory commission, flu policy during a severe season, and ethics concerns in a halted hepatitis B study in Africa.

Opinion | Parents Are Confused. I'm Worried for My Pediatric Patients. The consequences of rewriting the pediatric vaccine schedule

Read my @medpagetoday.com op-ed on recent U.S. vaccine policy changes framed as β€œrestoring trust.” The gap between that idea and reality is striking. Trust comes from clarity, evidence, and consistency.

The American Academy of Pediatrics continues to publish an evidence-based immunization schedule designed to protect children’s health and reflect what is best for children. Ironically, that evidence-based AAP schedule is now the β€œalternative” to the CDC’s.

@Parents: trust your pediatrician.

We will continue to provide clear, honest, evidence-based guidance focused on your child’s best interests, as we have for over a century. We’re committed to helping families make truly informed vaccination decisions, despite efforts to undermine that trust.

In my view, this reckless move risks harming children and fits a decades-long effort to undermine confidence in vaccines and dismantle the U.S. vaccination system.

There was also no meaningful opportunity for public or independent expert input before rewriting a schedule that protects nearly every child in the U.S.

This shift is based on an internal review, not the usual open, rigorous process with public and independent expert input.

There was no analysis of real-world impact on children and families:
β€’ hospitalizations
β€’ cancers
β€’ disabilities
β€’ preventable deaths

Under RFK Jr., U.S. plans to stop recommending most vaccines, defer to doctors The plan, which is not finalized, suggests children get fewer shots and shifts to a model telling parents to consult doctors to make their own vaccine choices.

@drhigginsmd.bsky.social: "many clinics and pediatricians will simply say they don’t recommend the Denmark schedule, which will worsen parental confusion. School vaccination requirements are set by state laws, and most require some of the vaccines that aren’t on the Denmark schedule" 🎁
