Breastfeeding by Hepatitis B Virus-infected Women
Decades ago, studies from the Far East demonstrated that HBsAg could be 
detected in breast milk in a large proportion of HBV-infected women.[48,49] 
Because many infants became infected before the availability of 
immunization, there was concern about the additional risk that breastfeeding 
might confer. However, around the same time, Beasley et al. [50] reported 
53% HBV infection in breastfed vs 60% in formula-fed infants. More recently, 
several studies have documented no difference in rates of perinatal 
infection between breastfed and formula-fed vaccinated infants, which was 
between 0 and 5% in both groups, although many of the women in these studies 
were HBeAg negative.[51,52] These data support the recommendation of the 
American Academy of Pediatrics that HBV infection not be considered a 
contraindication to breastfeeding of infants who receive the HBIG and HBV 
vaccine as advised.[53] In addition, it appears that breastfeeding does not 
interfere with the immune response to the HBV vaccine. In one group of 230 
infants, the rate of anti-HBs at 1 year of age was 80.9% in breastfed 
compared with 73.2% in formula-fed infants who received the HBV vaccine 
alone, and 90.9 vs 90.3% in those who received the HBV vaccine and HBIG.[54] 
It may be prudent, however, to counsel against breastfeeding by women 
receiving antiviral agents, because the safety of these drugs during 
lactation has not been demonstrated.
