Question
My child is three years old and should have received the A+C Meningococcal Vaccine, but during the hospital vaccination and payment, the nurse accidentally administered the Pneumococcal Vaccine instead, and it was an upper arm injection. Hello, I would like to ask what kind of complications might occur? The child is currently in normal condition and there is no special treatment. What kind of assistance can be provided? I mainly want to know if this will have any adverse effects on the child’s future? Are there any complications?
