This spontaneous case concerns a 23  year  old, female patient with relevant medical history of chronic low back pain, who experienced the unexpected, serious important medical event of neck pain. The event occurred a few hours after the administration of the second dose of mRNA-1273 vaccine. The report stated that the patient experienced headache, myalgia, arthralgia, intensified back pain, general inflammation in her body and that "her neck started locking up and couldn't turn due to the intense pain". She consulted a neurologist and in an MRI scan she had a "discbound" in the neck. She was treated with ibuprofen, Tylenol and received a Steroid injection for the pain and physical therapy 3 to 4 times a week. Although she expressed that this made her not incapacitating but with inability to function, she also referred the symptoms improved. Patient´s medical history of chronic low back pain (she stated she had back pain at the time of vaccination) could be confounding. The benefit-risk relationship of mRNA-1273 vaccine is not affected by this report.; Sender's Comments: This spontaneous case concerns a 23  year  old, female patient with relevant medical history of chronic low back pain, who experienced the unexpected, serious important medical event of neck pain.
