Question
The infant is nearly three months old and was underweight at birth, having not received the Hepatitis B vaccine. One week ago, the second dose of the Hepatitis B vaccine was administered, and since then, the infant has been experiencing persistent nausea and vomiting for a week, sometimes with fever and sometimes without. Is this situation normal? The infant has previously consumed fresh-squeezed juices, including orange juice, apple juice, and mango juice; could these have any impact on the body?
Answer
Persistent nausea and vomiting for a week following the second dose of the Hepatitis B vaccine in infants is not normal and should prompt an immediate visit to a pediatrician for examination.
