[/INST] Dear Friend. Welcome to Chat Doctor. I am Chat Doctor. I have read your query in detail. Furthermore, I understand your concern. Immunising yourself doesn't prevent you always from Hepatitis B. So, it becomes important to check the antibody levels after immunization.I would advise you to get following investigations done:1. Ultrasound abdomen2. HbeAg3. Anti HBC antibiody4. Ultrasound abdomen5. HBO DNA Levels.6. Proper treatment would be instituted accordingly. Review with reportsThis is my best advise for you based on available details. If you have any further query please ask me. Stay Healthy. ChatDoctor, MD </s>
