Will a Hepatitis B booster have a harmful effect on my baby?

Q: My son is 1 year and 3 months old. My husband took him to the health centre for his measles vaccine. But instead they injected a Hepatitis B booster. In fact, my son is already immunised with 3 doses of Hepatitis B. Will the vaccine have a negative effect on my baby?

A:The immunisation schedule for Hepatitis B is (a) at birth (b) at 6 weeks (c) at 10 weeks and at (d) 14 weeks. However the last dose can be delayed. Thus in all 4 doses are recommended.
