The events "develop back pain", "unable to stand-up", "pain with a diagnostic of possible muscle strain but nothing official as a diagnostic itself", "pain with a diagnostic of possible muscle strain but nothing official as a diagnostic itself" and "still unable to bend or sit low without pain or help support" were evaluated at the emergency room visit. Relevant laboratory tests and procedures are available in the appropriate section. Therapeutic measures were taken as a result of back pain. Therapeutic measures were not taken as a result of dysstasia, myalgia, muscle strain, joint range of motion decreased.  Additional information: The patient had no known allergies. The patient had received no other vaccines within 4 weeks prior to COVID vaccine. The patient had received no other medications within 2 weeks of vaccination. The patient had not diagnosed with COVID prior vaccination and had not tested to COVID post vaccination. Facility type vaccine was school or Health Clinic. After the shot the patient started to develop back pain to the point that as days go by he started hunch walking it was probably around 5 days of this symptoms until he was pretty much unable to stand-up walk that we had to take him to the ER then they ran a bunch of test as x-rays, blood test urine test etc, they all came out negative. He was send home to rest and Tylenol for pain with a diagnostic of possible muscle strain but nothing official as a diagnostic itself. It's been a week and the patient still unable to bend or sit low without pain or help support. It's important to address these symptoms because there was no data of side effects for kids with autism.  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.
