title: [Long-term efficacy of vaccination against hepatitis B in newborns: 13 years' follow-up].
abstract: OBJECTIVE
  To evaluate long-term efficacy of hepatitis B vaccination in newborns.
  
  
  METHODS
  In the past 13 years we followed up the children who had been immunized with hepatitis B vaccine at birth in 1986 every other year. At each follow-up visit, every child was tested for HBsAg, anti-HBs and anti-HBc.
  
  
  RESULTS
  HBsAg positive rate of these birth cohort was low (range between 0.46% and 0.98%) during 13 years' follow-up. Long-term efficacy of the vaccination in preventing HBsAg carriage was confirmed.
  
  
  CONCLUSIONS
  Thirteen years later no booster was after needed.
