title: [A study on relation between effect of HB vaccination and time of the second injection].
abstract: Three kinds of hepatitis B vaccination schedule in neonates were compared. The schedule included 0, 40 day, 6 month; 0, 50 day, 6 month; 0, 60 day, 6 month; and was controlled by the 0, 30 day, 6 month schedule. The results showed that there was no statistically significant difference among three kinds of schedule, no matter who were neonates of HBs Ag-positive mother or neonates of HBsAg-negative mother. These indicated that in areas with poor condition, such as mountain, island, the second injection of hepatitis B vaccine in neonates may be completed within 30-60 days.
