Birth to HBV infected woman
- Children born from positive HBVs mothers will receive in addition to the vaccine 0.5 ml of HBIG, intramuscularly, within 12 hours of birth; the first dose of the vaccine is given at the same time as HBIG, but in different places, the second and third doses of the vaccine are given in Romania at 2, respectively 4 months of life with booster at 11 months of life.
- It is recommended to test infants for HBsAg and anti-HBs antibodies at 9-15 months of life for monitoring the effectiveness/inefficiency of prophylaxis.
- Children with positive anti-HBs antibodies and negative HBsAg are protected, no longer require revaccination.
- Children with negative antiHBs antibodies and positive HBsAg require revaccination.
Breast-feeding
Breast-feeding is not, in theory, a risk factor for transmitting infection, especially if there are no lesions in the nipple.
However, by analyzing the benefit/risk ratio, it is considered that it is better for patients with hepatitis B not to breastfeed.
Infectant sexual contact
After sexual contact with a person with acute HBV infection, hepatitis B vaccine should be administered together with a HBIg dose of 5 ml within 14 days of infectant contact.
