My son had a febrile seizure; concussion; This serious case was reported by a consumer via interactive digital media and described the occurrence of seizure in a 19-year-old male patient who received Men B NVS (Bexsero) for prophylaxis. Previously administered products included Bexsero with an associated reaction of febrile convulsion (had a febrile seizure after his 1-year-old shots- had developed a fever and rash, refer case US2025AMR124514). Family history included epilepsy (the patient's sibling had epilepsy), multiple allergies (the patient's sibling was allergic to everything - nuts, soy, environmental, asthma, allergies, ADD, etc), asthma and attention deficit disorder. On an unknown date, the patient received Bexsero. On an unknown date, an unknown time after receiving Bexsero, the patient experienced seizure (Verbatim: My son had a febrile seizure) (serious criteria GSK medically significant and other: Serious as per reporter) and concussion (Verbatim: concussion). The outcome of the seizure was resolved and the outcome of the concussion was not reported. The reporter considered the seizure to be related to Bexsero. It was unknown if the reporter considered the concussion to be related to Bexsero and Bexsero Pre-Filled Syringe Device. It was unknown if the reporter considered the seizure to be related to Bexsero Pre-Filled Syringe Device. The company considered the seizure to be unrelated to Bexsero and Bexsero Pre-Filled Syringe Device. It was unknown if the company considered the concussion to be related to Bexsero and Bexsero Pre-Filled Syringe Device. This report is made by GSK without prejudice and does not imply any admission or liability for the incident or its consequences. Linked case(s) involving the same patient: US2025AMR124514 Additional Information: GSK Receipt Date: 27-SEP-2025 The case was received from patient's parent via interactive digital media. The patient had no more seizures until after they forced him to take the Meningococcal B shot for school when he was 19 years old and had received a concussion from that seizure. The neurologist misdiagnosed him with something terrible, and they believed her even though he had only 1 more seizure 4 months later. The parent followed her instruction for only 2 years when all she wanted to do was increase medication dose and prohibit him from driving despite him being seizure free for 6 months, then 12 month, etc. The physician said his blood levels on the medication needed to be higher or she would not allow him to drive and told her- perhaps he really did not need this medication he was below the blood levels for this medication and was seizure free. The doctor scoffed and dismissed and refused to sign off for him to drive. He drove anyway. The parent changed doctors, had a new MRI and the faint mass that the previous doctor thought she saw as something devastating was not anything- it was not there. So, for 2 years, previous doctor misdiagnosed were led down a path to believe that his seizures would increase and patient's life would be terrible, and they needed more meds, etc and had asked for patient's diagnoses to be corrected in his medical records - this was very important. Provoked vs non provoked seizures were important distinction to life insurance companies. Vaccines provoke seizures. The hospital had refused to change their incorrect diagnoses or acknowledge they were wrong. The reporter told them never to take vaccines again and the reporter stopped taking the Flu shot 14 years ago and had not had the Flu since. No covid shots either. The reporter tried calling the manufacturer of the Meningococcal B vaccine Glaxo Smith Kline to ask how long that vaccine might stay in her son's system, if it were a live or attenuated vaccination, if other issues other than seizures might occur, if it could cause that mass on my son's brain, etc, anything they had seen in trials similar to what happened with her son or if they had an antidote to reverse the vaccine or expel it from her son's body like steroids, etc. The batch number was not provided, and unable to contact the reporter.; Sender's Comments: A case of Epilepsy, unknown time after receiving Bexsero and Bexsero Pre-Filled Syringe Device, in a 19-year-old male patient. Report is inconsistent with causal relation to the vaccine product, considering implausible time to?onset and absence of biological plausibility and alternative risk factor (Family h/o epilepsy and multiple allergies ) US-GLAXOSMITHKLINE INC-US2025AMR124514:Same patient another dose
