Methods From March to September in 2011, 81 046 young students were selected as observation subjects. Hepatitis B serology was observed in three groups of pupils, middle school students and high school students. Results Among 81 046 primary and secondary school students, there were 60 726 anti-HBs positive, 1 467 HBsAg positive and 18 853 negative all-negative.
