A biotechnologically produced non-reproducible surface antigen is used as hepatitis B vaccine (HBV), It is therefore a non-infectious vaccine, and no risks to the fetus have been reported following vaccination of their mothers in pregnancy (ACOG 1993). Immunization of groups at risk is recommended; if possible, it should be given after the twelfth week of pregnancy. Ayoola (1987) described a series of 72 pregnant Nigerians who were seronegative for hepatitis B and were given two intramuscular doses of vaccine in the third trimester. One month after the second dose, 84% were anti-HBs positive. No significant adverse effects were observed in the mothers or their newborns. Passive transfer of anti-HBs occurred in 59% of = the newborns. The antibodies disappeared rapidly in these infants, and by 3 months only 23% had detectable antibodies (Ingardia ^ 1999, Reddy 1994). No 11 BsAg carrier status developed in this g1 group. In contrast, the infants born to HBsAg-positive mothers had § a cumulative rate of HBV events of 20%. The authors concluded E that HBV vaccine is safe and immunogenic in pregnant women. -i The passive immunity conferred on the infants is of short duration "g (Lee 2006). Therefore, in, for example, The Netherlands, newborns ™ from HBsAg-positive mothers will be vaccinated immediately or g otherwise within 48 hours after birth, preferably following the 'y administration of hepatitis-B immunoglobulin with booster vaccinations at the ages of 3, 4 and 11 months, according to the Dutch ^ Health Council advice (Geelen 2006). in

Recommendation. Vaccination of pregnant mothers in hepatitis 6 high-risk populations may provide adequate protection before the child is vaccinated. There are no negative adverse effects to be expected.
