Worried Mom

[Ccchuiccc]

My baby received the hbig shot at birth and started her vaccinations.  At 4.5 months, we tested her cause I couldn't wait until the suggested 9 months to see if she got infected. The blood work came back negative for the antigen and positive for antibodies (878 miu/ml). Does that mean I don't have to worry anymore and she cannot get hep b?  Should I still test her again at 9 months?  Her pediatrician does not "think" so.

just study, study and study and then you find everything on the internet...it takes time, years and some intellectual effort but i think almost anybody can study on the internet by correct websites

most doctors are ignorant because they just studied at university and then nothing, at university you just get the basics and very outdated.
researchers/doctors are the best because being researchers they never stop studying and updating

thanks stef.  How is it that you know so much?  Do you have a medical background?

you should test hbcab igg to know if hbv infected the baby but vaccine protected from infection

hbv vaccine can have a high failure rate if the mother is hbeag positive and high hbvdna at delivery.the best practice is get the mother on antiviral tenofovir and reach hbvdna und at delivery
and have vaccine at birth of course, this way you reach almost 100% response rates to vaccine because there s no virus to pass

so test hbcab igg (not igm) and if negative no concerns, if positive no concerns either but to be extra extra cautious:
test hbvdna pcr with sensibility 6 or 10iu/ml
test for hbsag with abbott architect machine or roches elecsys, these machines detect all hbsag mutants

occult hbv is rare but it exsists

Thank you.

I was breastfeeding from birth. I wasn't told to not breastfeed by my doctors so I assumed it was okay.

he is safe, he is not infected with hepatitis b and he has also develop antibodies against it, he will not be infected again.
