Additional information: reporter stated "yesterday my daughter that she is 2.5 years old, she went to the doctor office for her shots and she received like a MenB vaccine from Pfizer, the Trumenba and when I arrived at home, I realized that it was not approved for her age. I am really concerned because now she is having fever and very sleepy. She just want to sleep and looked like tired and she has like a fever, like 100-degree Fahrenheit. So, I am concerned because Pfizer did not approve it for her age. So, I do not know what to do."
