Canuto v. Secretary of Health and Human Services
04-1128
Fed. Cl.May 3, 2016Background
- Petitioners Darius and Teresita Canuto filed a petition under the National Vaccine Injury Compensation Program on behalf of their son ("DAC"), alleging vaccines caused his autism.
- DAC received multiple childhood vaccines in the Philippines and the U.S.; developmental concerns (speech delay) were documented beginning at age 1 and autism diagnoses were rendered in 2004 and confirmed in 2006.
- Special Master Hastings denied compensation, finding petitioners failed to prove causation-in-fact under the Althen framework.
- The special master gave strong weight to contemporaneous medical records and found petitioners’ factual assertions (e.g., multiple seizures) unsupported by those records.
- Expert testimony differed: petitioners’ expert Dr. Mark Levin relied largely on temporal association and general epidemiology; respondent’s expert Dr. Max Wiznitzer offered a contrary explanation grounded in DAC’s medical history.
- The Court of Federal Claims denied review and affirmed the special master, concluding the special master’s credibility assessments and legal application were not arbitrary or capricious.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether petitioners proved vaccines more likely than not caused DAC's autism (Althen prongs) | Vaccines (various combinations) caused DAC's autism; timing of onset supports causation | Petitioners failed to offer a reputable, legally probable medical theory or reliable proof tying vaccines to DAC's autism | Held: Petitioners failed all three Althen prongs; causation not proven. |
| Weight and credibility of experts | Dr. Levin: temporal correlation and epidemiologic rise in autism support causation | Dr. Wiznitzer: better credentials, coherent explanation tied to records; rebuts Levin | Held: Special master reasonably found Wiznitzer more persuasive; Levin's opinion speculative and equivocal. |
| Role of contemporaneous medical records vs later testimony | Parents and submitted literature support causation claims and reported history (e.g., seizures) | Medical records are reliable and do not support reported seizures or the asserted causal link | Held: Special master appropriately accorded greater weight to contemporaneous records; found parents’ later assertions unreliable. |
| Relevance of vaccines administered outside U.S. to Program eligibility | Petitioners argued foreign-administered vaccines are sometimes given domestically and should not be dispositive | Respondent noted potential jurisdictional/technical defect from foreign vaccination | Held: Court did not decide this issue because special master’s denial did not rely on it. |
