Sharpe v. Secretary of Health and Human Services, No. 19-1951 (Fed. Cir. 2020)Annotate this Case
In July 2010, L.M. was born at full-term and developed normally for six months. In February 2011, L.M. received childhood vaccines, including the diphtheria-tetanus-acellular pertussis vaccination. By that evening, L.M. had a fever, was lethargic, had poor muscle tone, and would not eat., Any disturbance caused L.M. to scream. L.M. began to have several seizures a day. At seven years of age, L.M. could crawl and walk with the assistance of a walker. She had a poorly coordinated grasp, suffered cortical visual impairments, and was nonverbal, though she could use a few signs to express ideas such as “yes,” and “no.” Testing revealed that L.M. had a genetic mutation.
In a claim under the National Vaccine Injury Compensation Program, L.M. alleged that the vaccinations administered to L.M. in February 2011, significantly aggravated L.M.’s pre-existing condition under two alternative theories. The Special Master denied the petition, finding that L.M.’s genetic mutation was “the most compelling explanation for her predisposition to develop a seizure disorder.” The Federal Circuit affirmed the denial of an “on-table” claim, finding no support for an argument that most encephalopathies do not become acute until after vaccination. The court vacated and remanded the denial of an “off-table” claim, which requires determining whether the child’s receipt of vaccinations significantly aggravated her seizure disorder in the face of an underlying genetic mutation.
