hepatitis B risk for my baby

[CollBB]

Hi,everyone:
Two days ago,my friend came to visit me with her daughter,her daughter licked the toy of my daughter,and then my daughter got it and licked it,before I noticed!My friend is hepatitis B+ but her daughter is not known.
I heared that baby's immute system is weak and that's why they could be infected through breastfeeding.My daughter is only 6 months old and has got 2 shots of hepatitis B vaccine.What if my friend's daughter is also hepatitis B+?Could the virus in slaver infect a baby?Should I worry?

I  know that hepatitis B is not transmitted by kissing.But is it still true for babies?

if hbv vaccine was injected she should be immune, just check her hbsab titer because there is a high hbv vaccine failure with current vaccines so it is best to check if hbsab developped

you should not worry anyway, it is extremely difficult to get hbv transmission that way, this said it is best to check hbsab anyway
