Might it be that a a mother vaccinated against hep b pass the antibodies on to an unborn child?

Might it be that a a mother vaccinated against hep b pass the antibodies on to an unborn child?

Yes: Antibodies against hepatitis b virus (hbsab antibodies from being vaccinated) are transferred from mother to fetus through the placenta. Babies get vaccinated during their first month of life and begin making their own antibodies, which is very important because the antibodies they got from mom only last about 6 months. ...Read more

Hep b surface antibody result :borderline range non reactive verified by analysis what's this mean ? Dr say wrong test vaccinated probably childhood

Other tests: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, it would have been helpful to have all the results, e.g., Antibody to Hep B core? If that was negative, your doctor is likely to be correct.

I am having hepatatisb and my wife is vaccinated against hep b if she give birth will the child get hepatitis b?

I am having hepatatisb and my wife is vaccinated against hep b if she give birth will the child get hepatitis b?

Is she negative?: If you as the male have hep b, and she does not, and it is documented, the risk is low for the baby. Some may not convert right away though, so she may be in the early stages of infection, and so covering the baby with hep b Immune Globulin at birth may be a good idea (just tell the OB about the exposure). Most likely risk would come from direct exposure from you to the baby, so immunize at birth. ...Read more

If a mother has hep b, will the child always get it?

Not with treatment: Without treatment, about 40% of babies born to hepatitis b positive mothers will get hepatitis b. However, there is a vaccine and immunoglobulin treatment that the baby should get soon after birth which can prevent the baby from getting hepatitis b. Make sure your OB and the baby's hospital doctor know about the hepatitis b so that they can treat the baby properly. ...Read more

Does hep b titer tell if you were previously infected? Vaccinated as child. Result showed 11miu/ml. 10miu is min. Is mine low & should I be concerned?

Does hep b titer tell if you were previously infected? Vaccinated as child. Result showed 11miu/ml. 10miu is min. Is mine low & should I be concerned?

Probably not: If you were vaccinated as a child and still have detectable antibodies left from that vaccine, chances are good that your vaccine ( it should have been a series of three doses) has protected you all this time and is still protecting you. More tests would be required to try to learn if you were ever infected, or are currently infected. The titer only says you have made a response to vaccine or bug. ...Read more
