Question
How long after the Hepatitis B vaccine can antibodies be detected in an infant’s body?
Answer
The Hepatitis B vaccine typically induces antibodies in the body within about a month. After the second dose of the vaccine, antibody levels are usually sufficient to resist the Hepatitis B virus. The third dose is administered to enhance immunity and extend the duration of antibody protection. If a child is diagnosed with liver disease, parents should cooperate with doctors for active treatment, including gastrointestinal decompression, and develop good hygiene habits. Additionally, children should be provided with a balanced diet and avoid consuming irritating and cold foods.
