''In these mothers with HBeAg, the risk of HBV perinatal transmission is reduced from 70-90% to approximately 5-15% when the infant receives postnatal immunoprophylaxis with both hepatitis B immune globulin (HBIG) and hepatitis B vaccine series; the risk is reduced to approximately 20% with regimens that use multiple doses of HBIG only or the vaccine series alone.''
So 5-15% is a big risk unfortunatelly.
HBEag positive have always been regarded as more infectious, i am afraid. But the HBIG and vaccine does work very well. Nothing is 100% though.
The risk of infecting the baby despite the vaccine and HBIG is greater for Hbeag positive mothers, right ?
There is still a small chance the HBIG and vaccine do not work. There is a study in Iran following up children who were treated this way but the virus still managed to infect the children.
However, most of the time. the HBIG and vaccine work.
You can... it is not a major issue now vertical transmission as was before.
Yes they can. After delivery the baby will receive HBIg and the vaccine against hepatitis B virus. Make sure you make all the necessary tests to see your HBV status.
