113 Fed. Cl. 210
Fed. Cl.2013Background
- Karl Paluck (born Jan. 15, 2004) had developmental delays and recurrent otitis media and erythema multiforme before receiving MMR, varicella, and Prevnar vaccines on Jan. 19, 2005.
- Contemporaneous testing (Oct. 2004 K.I.D.S. evaluation, Jan. 2005 pediatric visit) showed gross motor delay and mild-to-moderate language/fine-motor concerns; providers did not initially diagnose clear CNS disease.
- Within days of vaccination Karl developed fever, irritability, and fatigue; by February–April 2005 records (chiropractic notes, pediatric and neurology exams, and an April MRI later read as showing corpus callosum thinning) documented increasing spasticity, loss of skills, and global developmental regression.
- Petitioners alleged the vaccines caused or significantly aggravated an underlying mitochondrial disorder via vaccine-triggered immune activation → oxidative stress → neuronal injury; respondent disputed causation and timing.
- Procedural history: Special master denied compensation (Dec. 2011); this court vacated and remanded for incorrect application of legal standards (Apr. 2012), directing reconsideration whether the claim was a significant aggravation (Loving) and to reassess the record; on remand the special master again denied relief (May 2013); this court reviewed and vacated that denial and awarded entitlement, remanding for damages.
Issues
| Issue | Paluck (Plaintiff) Argument | Secretary (Defendant) Argument | Held |
|---|---|---|---|
| 1. Proper classification: new injury vs significant aggravation | Karl had essentially normal CNS function pre-vaccine; his severe regression was a new injury caused by vaccines | Karl showed preexisting developmental problems and immune stress; the claim should be treated as significant aggravation | Court affirmed significant-aggravation classification (Loving) — Karl had preexisting delays and immune stressors, so Loving applied |
| 2. Medical theory (Althen/Loving prong 1) — plausibility of vaccine → oxidative stress → neurodegeneration | Provided peer‑reviewed studies, case reports (Poling/Hannah), and animal data showing vaccines/fever can cause oxidative stress in susceptible mitochondrial patients | Theory lacks definitive human epidemiologic proof; respondent contested extrapolation from animal studies/case reports | Court held petitioners met the requisite preponderance standard for a reputable, legally probable theory (need not be medically certain) |
| 3. Logical sequence (Althen/Loving prong 2) — did events show vaccine-caused aggravation in Karl’s case | Temporal sequence: fever within 48 hrs, persistent systemic signs, first spastic notation Feb. 11, neurologist referral Mar. 24, abnormal MRI & marked spasticity by Apr. — consistent with Frye’s cell‑level then clinical decline | Respondent argued records show fluctuation/improvement after Jan. 19 and that chiropractic notes/unverified observations are unreliable; no clear immediate neurologic decline consistent with theory | Court found the clinical record and literature sufficiently consistent with the proposed sequence and that petitioners carried their burden on causation sequence |
| 4. Temporal relationship (Althen/Loving prong 3) — medically acceptable interval | Vaccine reaction began within 48 hours (fever) and meaningful neurologic deterioration manifested over weeks–months; literature and case reports allow this timing | Respondent favored a narrow window (≈2–3 weeks) and argued Karl lacked objective neurologic decline within that strict interval | Court rejected a rigid short window; considering Edmonds, Shoffner, Poling, and record, court found the timing medically acceptable and within a plausible interval and held causation on timing met by a preponderance |

- Loving ex rel. Loving v. Secretary of Dep’t of Health & Human Servs., 86 Fed. Cl. 135 (2000) (articulates six‑part test for significant aggravation combining Althen factors with pre/post‑vaccination inquiry)
- Knudsen ex rel. Knudsen v. Secretary of Dep’t of Health & Human Servs., 35 F.3d 543 (Fed. Cir. 1994) (preponderance standard does not require medical or scientific certainty)
- Moberly ex rel. Moberly v. Secretary of Health & Human Servs., 592 F.3d 1315 (Fed. Cir. 2010) (clarifies that petitioners must give a reputable medical explanation that is legally probable)
