Abstract
Ninety-nine preterm infants with birth weights < 1750 gm had three doses of hepatitis B vaccine. Fifty-seven received the first dose when they weighed > or = 1000 gm (group 1) and 42 when they weighed > or = 2000 gm (group 2). The final seropositive rates and geometric mean titers of group 1 infants (79%, 61 mIU/ml) and group 2 infants (91%, 262 mIU/ml) were less than that of 43 normal term infants (100%, 679 mIU/ml).
