      2, Is it ok for her to Breast-feeding our child?
      3, what should I do to pretect our child from Hepatitis B before and after it born?

No worries. Thanks Stephen :)

My apology for the typo. Of course it is 10 mIU/mL  as you stated.

Response to Vaccine

A full series of vaccine is desirable, although 32 to 56% of persons achieve protective levels of anti-hepatitis B surface antibody (HBsAb) with a single dose of vaccine, a percentage that rises to 70 to 75% with two doses. A third dose generates a protective response in more than 90% of healthy vaccinees and provides long lasting protection[8,9]. Certain conditions are associated with decreased response to vaccine including age greater than 40 years, male sex, genetic factors, obesity, tobacco smoking, alcoholism, renal disease, HIV infection, and other immune compromising conditions[6,10,11,12,13,14,15,16,17]. After completion of a vaccine series, a HBsAb level >=10 mIU/mL is considered protective. In general, protection generated by a complete vaccine series is believed to last for at least 15 to 20 years in healthy individuals. Immunity in healthy adults and children appears to persist even though antibody levels may decline over time to low levels, even below detectable limits[18,19,20,21,22,23].

thanks Stephen and enolia, you are so kind.

[enolia]

Just to be certain, the unit is really mUI/ml, so an immune protected state has to show a value higher or equal to 10mUI/ml or equal or higher than 10 UI/l.

[StephenCastlecrag]

"HBsAg antibodies count should be > 10mUi/ml. "

I second that good advice by enolia. If your HbsAg antibodies count is below 10 iu/ml, which I don't think so, you can get vaccinated again.
Also, HBeAg-ve patients are considered to be not very infectious.

[enolia]

HBsAg antibodies count should be > 10mUi/ml.

[philippe567]

thanks you very much

[enolia]

Yes you are safe according to the latest studies. If you d like you could get tested again for antibodies and immunity, just for yourself to feel better.

[philippe567]

so it means I'm safe?

[enolia]

Oh I see, good to know that China is taking HBV seriously, I had no idea about the Big and small three :)
Philippe567, The most recent studies say that HBV vaccine provides indefinite protection not only 15 or 20 years, especially if the initial shot worked adequately and whether your HBsAb counts decreases or not over time.
Some other studies say that it is protective for at least 25 years.

[philippe567]

yes stephen is right , My wife has small three, I'v got  vaccination in my teenage. I got test about 3 years ago and at that time I still had antibody. WHO had said the  vaccination will protect people at list 20years.  what I want to know is whether I'm safe to have sex with my wife without protection. To have a child need unprotect sex as you know. :)

[StephenCastlecrag]

People from China get tested more often than everyone - they are tested when they go to school, go to university, applying for a job and then annually when they are employed.
Big three means: HBsAg+ve, HBeAg+ve, anti-HBcAg +ve.
Small three: HBsAg+ve, anti-HBcAg+ve.

Hope I got it right.

Since you already had unprotected sex, before getting any vaccine you should get tested first for hepatitis b, if you are already infected ( I hope not) then vaccine won't help...Get tested first. If you need  more info about pregnancy and breastfeeding, I went through the same experience, you can message me, also check the forum thread called 'Pregnancy and breastfeeding while on Tenofovir (Viread)'.
