She filed a petition alleging the vaccine caused her subclinical seizures and epilepsy. The case was initially framed as a Table injury claim but evolved into an off-Table claim, with Ms. Singleton arguing the vaccine significantly aggravated a pre-existing condition of microvascular angiopathy. She presented expert testimony suggesting the vaccine induced an inflammatory response that worsened her vascular disease, leading to stroke and subsequent epilepsy. The respondent argued that Ms. Singleton's symptoms were more likely caused by a viral syndrome diagnosed shortly after vaccination or that her epilepsy predated the vaccination. The court reviewed the evidence, including medical records and expert opinions from neurologists Dr. Carlo Tornatore for the petitioner and Dr. M. Steven Evans for the respondent. The court found that Ms. Singleton did not preponderantly establish a causal link between the flu vaccine and her alleged injuries. Specifically, the court found that her pre-vaccination cognitive complaints were not clearly distinct from her post-vaccination complaints, that the onset of her epilepsy was not clearly established as post-vaccination, and that the medical evidence did not support a theory that the flu vaccine could cause or aggravate microvascular angiopathy leading to stroke. Consequently, the court concluded that Ms. Singleton had not met her burden of proof and dismissed her petition.","is_minor_inferred":0,"is_pediatric_broad":0,"special_master":"Daniel T.
