An Open Letter to ZDoggMD

Note: This article is for general information and commentary only and is not a substitute for personal medical advice. Talk with your own health care professional about decisions for you or your child.

Dear ZDoggMD,

You’ve spent years doing something a lot of doctors only talk about: stepping out of the clinic and into the wild arena of online health communication. You rap about vaccines, roast pseudoscience, and use humor to try to keep people alive. That’s no small thing. As a result, millions of people who will never read a New England Journal of Medicine article have at least heard a doctor say, “Hey, maybe don’t get your health information from your cousin’s Facebook group.”

That’s why your voice matters so much in conversations about COVID-19, vaccines, and kids. You’ve described yourself as “arguably the biggest advocate for vaccination on social media,” and you’ve platformed trusted experts like Dr. Paul Offit to explain why vaccines for children save lives. You’ve shown your own daughter getting vaccinated, which is powerful modeling for hesitant parents.

But precisely because your platform is big, your words carry extra weight. When the science is still evolvingand when bad actors are working overtime to twist that scienceany drift from accurate, balanced messaging doesn’t just spark “debate”; it can shape real-world behavior. That’s the concern at the heart of this letter, and it echoes critiques raised by pediatricians and science communicators at Science-Based Medicine, a site devoted to cutting through hype and pseudoscience in health care.

Why Science-Based Medicine Cares What You Say

Science-Based Medicine (SBM) exists for a very specific reason: to evaluate health claims through the lens of evidence, not vibes. Its editors and contributorspeople like Steven Novella and David Gorskihave spent years analyzing how pseudoscience spreads, how “alternative” treatments are marketed, and how even well-meaning physicians can wander off the evidence-based path.

Skeptical medicine isn’t about being cynical; it’s about insisting that information offered to the public should actually line up with the data. That means:

• Presenting risks and benefits in context, not cherry-picking the scariest numbers.
• Owning uncertainty where it existsand not pretending nuance is whatever we personally find comfortable.
• Recognizing that “I’m just asking questions” can quickly become “I’m just amplifying misinformation.”

In that light, SBM’s open-letter critique isn’t about whether you’re “pro-vaccine” in general. It’s about how your messaging around COVID-19, children, and vaccine risks sometimes departs from the full scope of evidence we haveespecially when it comes to what parents actually hear versus what we think we said.

Kids and COVID-19: The Risk Isn’t Zero

You’ve often emphasized that most kids with COVID-19 do well, and that’s true. The vast majority have mild illness and recover without serious complications. That’s one of the few gifts this virus has given us.

But “most kids are fine” can accidentally sound like “almost no kids are harmed,” and that’s where the data push back. In the United States, hundreds of children have died of COVID-19, and hundreds of thousands have been hospitalized since the pandemic began. Many of those children had underlying conditions like obesity or asthma, but not all did. For their families, “rare” doesn’t feel reassuring; it feels like a lifetime of birthdays that will never happen.

Pediatric data from the CDC and American Academy of Pediatrics show that COVID-19 has consistently ranked among the leading infectious causes of death in children and teens in the U.S., even after vaccines and better treatments became available. That doesn’t make it Ebola, but it does make it a threat we can’t wave away with “hardly any.” When respected physicians repeat lines that minimize those deaths, anti-vaccine activists don’t challenge themthey quote them.

Beyond Death: Hospitalization, MIS-C, and Long COVID

Focusing only on mortality also hides the broader burden of disease:

• Hospitalizations: From fall 2020 to spring 2024, roughly 234,000 children under 18 in the U.S. were hospitalized with confirmed COVID-19, and a substantial fraction required intensive care.
• MIS-C and myocarditis from infection: Multisystem inflammatory syndrome in children (MIS-C) is rare but can be devastating, often involving inflamed hearts, shock, and the need for life support.
• Long COVID: Clinics at places like Yale Medicine have seen children with months-long fatigue, headaches, cognitive issues, and exercise intolerance after infection, and more recent multicenter studies continue to track persistent symptoms and functional impairment.

None of this means parents should panic. It does mean honest communication has to capture the whole picture: for most kids, the risk is lowbut not trivialand vaccines exist specifically to push that already-low risk even lower.

Vaccines for Kids: What the Evidence Actually Shows

One of SBM’s key concerns is that your content has often zeroed in on vaccine myocarditis while giving relatively little airtime to the overwhelming evidence that vaccines dramatically reduce severe outcomes in adolescents.

Real-world data and clinical studies have shown that mRNA vaccines:

• Cut the risk of hospitalization for adolescents by around 90–95% in earlier waves of the pandemic.
• Nearly eliminate ICU admissions and deaths among vaccinated teens in several cohorts, with almost all severe cases occurring in unvaccinated patients.
• Reduce the risk and severity of MIS-C, with vaccinated children rarely needing respiratory or cardiovascular life support.

On the safety side, myocarditis after mRNA vaccinationespecially after the second dose in teen boysis real, and pretending otherwise would be dishonest. But here’s what large follow-up studies and CDC reviews have found:

• Most cases are mild or moderate, respond to short hospital stays and simple therapies, and resolve clinically within weeks to months.
• Medium-term follow-up suggests most affected young people are considered recovered and report quality of life comparable to peers, though ongoing surveillance is essential.
• Myocarditis risk from COVID-19 infection itself appears at least as high and often higher than the risk from vaccination, especially in adolescent males and young adults.

When we talk loudly and repeatedly about vaccine myocarditis but only faintly mention the benefits, the net effect for many parents is simple: “The vaccine sounds scary, and I don’t hear enough about why it’s worth it.” That’s not a balanced risk-benefit conversation; it’s just a more sophisticated way of nudging people away from vaccination.

The Platform Problem: Guests, Nuance, and Echo Chambers

Another major issue raised by SBM and other skeptics is how your show amplifies certain voices. You’ve repeatedly hosted commentators who minimize the dangers of COVID-19 in children (“no healthy child has died,” for example) or drastically overstate vaccine harms, often relying on misinterpreted databases like VAERS or very narrow datasets.

In theory, you’re just “hosting a debate.” In practice, we know from decades of risk-communication research that:

• People remember vivid stories more than careful caveats.
• Familiar claimseven false onesstart to feel true simply through repetition.
• When the host isn’t clearly correcting misinformation in real time, many viewers take silence as agreement.

Skeptical conferences like NECSS, which Science-Based Medicine helps sponsor, were built around the idea that experts should challenge misinformation robustly and transparently. When guests on your show make easily fact-checked claims that downplay pediatric COVID-19 deaths or ignore hospitalization data, the “alt-middle” stance can look less like nuance and more like asymmetric skepticismharsh scrutiny for vaccine risks, gentle nods for infection-related harms.

Nuance Isn’t Symmetry-Free

True nuance isn’t:

• “The virus is no big deal for kids, but the vaccine is scary.”
• “If you’re young and healthy, you don’t really need protection.”
• “Any uncertainty about vaccine safety cancels out everything we know about its benefits.”

Real nuance says:

• “Most kids will be okay, but some will get very sick or die.”
• “Vaccines greatly reduce severe outcomes, and the known risks are rare and usually mild.”
• “Risk is never zero in either direction; your job as a parent is to pick the much smaller risk.”

That’s the kind of nuance the science supportsand the kind that a self-described leading vaccine advocate is uniquely positioned to communicate clearly.

What a Science-Based Course Correction Could Look Like

So what would it mean, practically, for your platform to align more closely with science-based medicine, especially for children?

1. Lead With the Full Risk–Benefit Picture

When you discuss myocarditis, lead with the comparative risk:

“Yes, myocarditis can rarely occur after vaccination, especially in teen boysand it’s usually mild and resolves quickly. COVID-19 itself can cause more frequent and more severe heart inflammation, hospitalizations, and deaths. Overall, the vaccine is still the safer path.”

That framing is accurate and honestand it matches the conclusions of CDC guidance and follow-up studies.

2. Give Evidence of Vaccine Effectiveness Equal Billing

Make episodes dedicated to what we know about efficacy in adolescents. Highlight large real-world studies showing lower hospitalization, ICU admission, and MIS-C rates among vaccinated kids.

Parents need to hear, explicitly and often, that the vaccine isn’t just a “maybe”; it’s a powerful tool to make worst-case scenarios far less likely.

3. Fact-Check Your Own SideOut Loud

When guests make claims that contradict established dataabout deaths, hospitalizations, or long COVIDpause and clarify. Bring in pediatric infectious disease specialists who work directly with hospitalized children, not only contrarian commentators whose takes play well on talk shows and social media.

Scientific skepticism isn’t just for things we already disagreed with. It has to cut through our own biases, too.

4. Acknowledge Uncertainty Without Feeding Cynicism

It’s perfectly reasonable to talk about unknownslong-term myocarditis outcomes, optimal boosting schedules, or how long immunity after vaccination or infection lasts in kids. But the message should be:

“We don’t know everything, but we know enough to act now, and we’ll adjust as better data come in.”

Not:

“We don’t know everything, so maybe do nothing and hope for the best.”

Reflections from the Front Lines: Experiences in Science-Based Communication

To understand why this open-letter conversation matters so much, it helps to look at the lived experiences of people navigating COVID-19 and vaccines with kids in the real worldfamilies, clinicians, and science communicators trying to make the best possible choices with imperfect information.

Picture a pediatrician in a busy community clinic. Her waiting room is full of kids with coughs, rashes, and the usual parade of childhood adventures. In 2021 and 2022, she also saw something new: previously healthy children struggling to breathe from COVID-19 pneumonia, toddlers admitted with MIS-C, and teenagers who went from soccer practice to the ICU in a matter of days. She isn’t living in an abstract risk-ratio chart; she’s walking past worried parents sitting on plastic chairs outside the pediatric ICU. For her, “rare but real” isn’t a sloganit’s the kid in Room 6 whose favorite stuffed animal now lives on a hospital windowsill.

Then there are the parents who arrive at clinic with printouts and bookmarked videos. Some of those clips are yours. They replay a line about myocarditis or listen to a guest say that “healthy kids don’t die of COVID” and feel their anxiety spike. They’re not bad people; they’re overwhelmed. They’re trying to reconcile what they heard online with what their local doctor is saying: “Your child is much more likely to be helped than harmed by this vaccine.” When messaging from trusted physicians clashes, the easiest option is often to do nothingand in a pandemic, “nothing” is still a decision with consequences.

Science communicators working in the skeptical space feel that tension daily. They watch bad information about COVID-19 and children pinball through social media, from fringe blogs to national TV. They see cherry-picked statistics go viral while careful contextual analysis gets a few polite retweets. They also see how quickly nuance can be weaponized: a single sentence about uncertainty clipped out of a one-hour conversation, repackaged as “Doctor admits vaccine may be unsafe.”

That’s why platforms like yours are so importantnot just for what they say, but for what they choose to emphasize. When you highlight a thoughtful discussion of how to improve vaccine safety monitoring, you can move the whole conversation forward. When you host a guest who casually dismisses pediatric COVID-19 deaths or misuses spontaneous-reporting data to claim “countless hidden vaccine fatalities,” you unintentionally hand a megaphone to narratives that public-health workers are desperately trying to counter.

And finally, there’s the long tail: kids and families dealing with the aftermath. A teenager who got COVID-19 before vaccines were available and now can’t keep up in school because of fatigue and brain fog. A sibling who watched their brother spend weeks in the hospital. A parent who regrets delaying vaccination after spending months on the fence, guided partly by voices that emphasized vaccine risks far more loudly than infection risks. These stories rarely go viralbut they’re as real as any side-effect report.

The experiences of clinicians, parents, and patients all point to the same conclusion: communication isn’t neutral. When we choose what to spotlight and what to leave in the shadows, we’re shaping outcomes, not just opinions. For someone with your reach, that’s both a burden and an opportunity.

Conclusion: A Challenge From One Science-Lover to Another

None of this letter erases the good you’ve done. You’ve helped push back on anti-vaccine myths, explained complex topics with humor, and made countless people feel less alone in a dysfunctional health care system. Your “Health 3.0” vision of a more humane, patient-centered system speaks to real problems in American medicine.

But being a leading voice for vaccines on social media means holding yourself to an even higher standard of evidence, especially when the topic is kids. It means:

• Talking about vaccine risks accuratelyand giving vaccine benefits equal, repeated emphasis.
• Refusing to platform uncorrected misinformation from guests, even when they’re colleagues or friends.
• Making sure parents walk away with a clear understanding of how the numbers stack up, not just a vague sense of unease.

Science-based medicine isn’t about winning internet arguments; it’s about giving people the best possible chance to make decisions that keep their kids alive and healthy. In that mission, you, SBM, pediatricians, and public-health folks are allat least in theoryon the same team.

So here’s the ask: Use your platform to model what truly balanced, evidence-driven communication about COVID-19 and children looks like. Quote the studies showing vaccine effectiveness as often as you quote myocarditis statistics. Invite guests whose expertise comes from treating sick kids, not from crafting viral contrarian takes. And when you get new information that changes the picture, say so plainly. That’s not weakness; that’s exactly what following the science looks like.

If you really want to be the biggest advocate for vaccination on social media, this is how you prove itnot just with what you believe privately, but with what your audience actually hears.
