Counting Integrity: What Do We Do When A Bioethicist Cannot Count?

Art Caplan was once caught on video declaring war on his fellow Americans those who want to refuse vaccines. Now he wants them to trust his math.

So-called “bioethicist” Art Caplan’s MedPage Today editorial claims that most American children receive “about 30 doses” of vaccines across 16 diseases. By contrast, Secretary Robert F. Kennedy Jr.’s HHS team, through the January 2026 Høeg/Kulldorff report, documented a far more complex and expansive exposure count: up to 92 discrete vaccine events, and many more when considering strain-level detail. This article reconstructs the counting systems behind those conflicting claims, dissects CDC 2025 vaccine schedule assumptions, and demonstrates—using real biological, scheduling, and economic logic—why Caplan’s framing fails both analytically and ethically.

Caplan’s Fractured Arithmetic of Vaccine Counting

Caplan’s assertion of “about 30 doses” contains no definition of what a “dose” is. A shot? A disease-target? A product component? The CDC’s own immunization guidance makes no such simplification. The reality is that there are at least four separate, equally valid vaccine exposure metrics:

1. Product-based doses: Every time a vaccine is administered, regardless of combo structure.

2. Component targets: Every unique disease targeted, regardless of how many in one shot.

3. Strain-level (valency): Each serotype, strain, or viral type targeted (e.g., PCV20 = 20).

4. Taxon/species-based: Each biologically distinct pathogen.

Caplan does not disclose his metric, but by excluding annual flu, COVID, HPV, MenACWY, and collapsing all multivalents into a single count, we reconstruct that he is counting only around 30 injections, stopping at adolescence.

By contrast, Høeg/Kulldorff’s “up to 92” refers to component doses, including:

• Routine childhood series

• Annual flu and COVID boosters

• Full HPV and MenACWY series

• RSV-mAb

• Maximum possible schedules (e.g., 3-dose HPV, 3-dose rotavirus)

This metric aligns with CDC coverage policies, CPT billing codes, and biological targeting logic.

CDC 2025 Schedule: Real Numbers, Real Complexity

An exact tally of vaccine exposures from birth to age 18 under the 2025 CDC schedule reveals the discrepancy. For example:

• HepB: 3 product doses = 1 species = 1 component = 1 strain

• DTaP: 5 product doses × 3 targets = 15 components

• PCV20: 4 doses × 1 component = 4, but targets 20 serotypes

• HPV9: 2 or 3 doses = 9 strains × 2 = 18 strain-level exposures

• COVID-19: 1/year × 18 years = 18 components (or strains)

Caplan’s Ethical Framing Fails Its Own Logic… And Could Cost Pediatricians Large Sums of Profit

Caplan argues that Kennedy’s policy violates the ethical principle of beneficence by allowing disease risk to increase. But ethical analysis requires transparency about both benefits and risks. Caplan omits:

• Risk of intussusception from rotavirus

• Febrile seizures from MMRV

• Myocarditis from mRNA COVID vaccines

• Aluminum exposure associations with asthma (VSD 2023)

• Mention of product warnings that all vaccines come with a risk of death.

He makes no comparison at all to the risks of serious disease, hospitalization of deaths from other countries that seem to get by with far fewer jabs.

He also fails to note that no CDC schedule-wide safety trial has ever been conducted, and multiple vaccines were approved without saline placebo trials. Informed consent, in Caplan’s view, is apparently only valid if it reinforces his side.

Comparative Schedules: U.S. vs Peer Nations

The HHS report shows that the U.S. recommended more diseases and more product doses than any other nation. Denmark vaccinates against 10–11 diseases. The U.S. vaccinated against 18, not counting COVID. When Caplan says the U.S. is “in line” with peers, he ignores this comparative data and the vaccine landscape of nations like France, Japan, Germany, and the U.K.

MMRV, Combination Products, and Dose Compression Games

Caplan’s count ignores how strain-compressed products like MMRV and Pentacel alter perception. Giving MMR + Varicella separately = 2 shots. MMRV = 1 shot. But both contain 4 live virus strains. Similarly, Pentacel collapses DTaP + Hib + IPV into 1 injection.

Combo products reduce needle counts, not biological exposures. Counting them as “1 dose” ignores reality.

Financial Incentives and Pediatric Reimbursement

Caplan omits that pediatricians are compensated per administration. Under CPT codes 90460/90461, each component adds revenue. Vaccine manufacturers, providers, and CMS all count components, not injections, when billing.

Providers and CMS bill per dose administered, using product codes. Components are used to adjust administration reimbursement when counseling is documented.

Administration CPT codes:

90460: For the first antigen in a vaccine administered during a counseling session

90461: For each additional antigen/component in the same vaccine, billed as add-ons

Caplan’s math would upend the entire Medicaid and VFC billing system if applied seriously.

He omits his own conflict of interest statement, as well.

The True Exposure Ledger

Thanks to comprehensive data modeling from the CDC schedule and biological products, we now know:

• Strain-level exposure: 231 by age 18

• Component-level: 79

• Species-level (‘disease’): 16

• Caplan-style injection collapse: ~30

Each method is internally consistent. But only Caplan presents his total without disclosing his assumptions.

Conclusion: Disclose or Disqualify

If Caplan wants to participate in the policy conversation, he must disclose what he counts and why. Until then, his critique of HHS’s up-to 92-dose claim is nothing more than rhetorical sleight of hand. Science must clarify. Bioethics must quantify. Policy must account.

The future of vaccine trust is harmed by the minimization of risk perception. That train left the station long ago.

Caplan still has yet to receive the memo.
