In December 2019, the pt was recommended by his health care provider (HCP) to receive the Quadrivalent Human Papillomavirus (Types 6,11,16,18) Recomb. Vaccine (GARDASIL), which was touted as a safe and effective vaccine for preventing cervical cancer and the pt consented to being injected with the vaccine. Therefore in December 2019, at 19 years old, the pt received his only dosage of the Quadrivalent Human Papillomavirus (Types 6,11,16,18) Recomb. Vaccine (GARDASIL) (dose, units, route of administration, lot#, and expiration date were not reported). Following his vaccination, pt began experiencing heart racing and pounding, and numbness on the left side of his body. It slowly became worse to the point he thought his body was shutting down and he feared he might suffer a heart attack or stroke. Thereafter, pt continued to experience numbness and tingling on the entire left side of his body. His heart palpitations continued and worsened. In addition, pt experienced migraines, chronic fatigue, insomnia, and difficulty falling asleep and staying asleep, brain fog and vision problems. The pt was ultimately diagnosed with chronic fatigue syndrome, heart arrhythmia, and heart palpitations. As the months progressed, so did pt's symptoms. He has been seen by multiple physicians and specialists for his complaints, which now included chest pain, heart arrhythmia and palpitations, numbness on the left side of his body, insomnia, brain fog, vision problems, chronic migraines, headaches, and chronic fatigue. As a result of his post-GARDASIL symptoms, pt has been unable to engage in activities that a normal young person would enjoy. Prior to receiving the GARDASIL vaccine, he was an active person who played sports. He also frequented the gym and enjoyed going on walks. After receiving the vaccination, pt has avoided physical activities due to body pain and fatigue. He continued to experience brain fog and vision troubles, which made it difficult to read. He suffered from chronic migraines. Furthermore, pt's symptoms have interfered with his work, and he has been forced to use sick time when these symptoms were triggered. In addition, due to his symptoms, pt has missed many classes during his academic career and has been forced to register for only online courses. Based upon his chronic and severe post-GARDASIL symptoms, pt has been diagnosed with various medical conditions, including but not limited to chronic fatigue, heart arrhythmia, and heart palpitations. Pt contended that his GARDASIL injection caused him to develop serious and debilitating autoimmune, autonomic, and neurological injuries, including but not limited to chronic fatigue, heart arrhythmia and palpitations, as well as a constellation of adverse symptoms, complications, injuries, and other adverse events, many of which were alleged herein and all of which were caused by GARDASIL or otherwise linked to his GARDASIL-induced autoimmune disorder. The outcome of all events was considered as not recovered.  Upon internal review, the events of arrythmia and autoimmune disorder were considered to be medically significant, and all the events were considered to be disabling.
