<s>[INST] hi sirmy husband is 29yrs and we got to know that he is infected with heb b under emp visa medical process in dubai. I too got tested but its negative for me. Now i hav taken vaccination for the same. We just want to confirm that even aftr taking the vaccination do I have chances of getting hep b??? coz we are planning to hav a child..how far its effective?pls help me out.thankx in advance [/INST] Hi, Almost 90% protection is achieved after booster dose of hepatitis B vaccine however the protection level fall to as low as 75% within 10 years of vaccination, Hepatic is 10 times more contagious than HIV. Try to use condom while having sex with your husband, as though immunization provide protection yet 10% risk is a high risk. You can plan a child and immunization will again be repeated during pregnancy and after birth however chances of child having infection are quite high despite vaccination. Hope I have answered your query. Let me know if I can assist you further. </s>
