Hello. Very Good morning. According to vaccination schedule the baby is vaccinated for Hepatitis B infection in first 6 months of total 3 doses and first dose at birth, second dose 1 Month apart & 3rd dose to be given at 6 months. So Hepatitis B vaccination booster dose is required,  when your child is 5 years old. And every 5 years your child would be receiving booster dose lifelong. I think you understood Very well about Hepatitis B vaccination. At 10 th week of your child,  he/she needs DPT -2nd Dose, Oral Polio vaccine - 3rd dose,  & HIB vaccine - 2nd dose. HIB VACCINE will protect your child from haemophilus influenza Type B vaccination. At 10 th week of your child's age,  there is no need for Hepatitis B vaccination. Don't do this. This 10 th week vaccination schedule is according to WHO vaccination program worldwide. Regards.
