Clinical course: It was reported that reporter's son has had very bad side effects with the vaccine. Patient and reporter got vaccinated at about 7 and on the night, at about 2 a.m, patient woke up feeling bad, where reporter told him that it was normal, that the vaccine causes reactions in his body and told him to go to sleep, he dozes off the rest of the night, but he did not feel well at all. The next day when he woke up for breakfast, he said that he was having a really bad headache, where reporter could not even focus on what he was talking about. Reporter told him to take 2 Advils and that would do him well. At the table he started to shiver like with chills, so reporter told him to get up from the table and to cover up. Then, the patient (son) was having strong chills, so reporter went down to see him, he said that he felt bad, and that was the worst thing he had ever felt in his life. Reporter told him to calm down, and checked his temperature, but he wasn't feverish, and he was asked to get up to go to wash his face, and on a scale of 1-10, his chills were found to be 2, but when he stood up, it went to 10, they were so strong that he was shrunk, his hands were stuck to his body and super stiff, he couldn't even stand. Reporter and patient went to the hospital, the closest one was a medical center right in front of the house, but it would be opened at 10, but it was 9. Patient was shaking in the car and was praying not to die, they went to the hospital, the guard told them to wait around 20-40 min. While they were waiting, patient started to vomit and vomit, while he vomited, the chills went down. With the reduced chills, reporter called a doctor and he said that those were the side effects from the vaccine, which were uncommon but that he was going to improve from then on. Reporter was calmer, everything there but the headache went away. A doctor in the hospital told them that those are side effects of the vaccine, that they would take care of patient but most likely they would give him paracetamol. Reporter gave him paracetamol and all day he was in bed, and he was feeling unwell all day, but the intense chills did not come back. Reporter spoked to the pediatrician to see if he authorizes them to travel because that day, they were going to take an airplane, the pediatrician said it would be okay and that due to the intensity of the chills it could be considered as a seizure with neurological loss, but the patient never lost consciousness. But in the plane, he felt bad, his head, throat, ears got hurt. When they arrived, patient told like he feels like he was having a cold, even his throat hurt a lot. Aside from the sore throat, he had very strong migraines and even reporter also had but reporter was aware that headaches were associated with the vaccine. The pediatrician referred him to a pediatric neurologist because he was having headaches until he vomited. The neurologist performed the electrocardiogram, the next day at the appointment with the neurologist, he said that there was evidence that his body had been under stress, but from what neurologist could see in his head, led conclusion that there was no neurological damage, it would pass. Over the next few days, patient said that his ear hurts and that he can't hear, the pediatrician said that he was now worried because patient already had many side effects from the vaccine. The specialist checked child's ear, where did not have any inflammation or infection. Specialist said that the vaccine can cause the ear to become inflamed and when half of the ear is inflamed, might lose hearing. Reporter's son is not totally deaf, but he lost 60 percent of what he heard in his left ear, the doctor said it could be reversed in a while, there is a specific time to fix what was going on.  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.
