title: [The coverage of hepatitis A vaccine among 2-29 year olds and the reporting incidence of hepatitis A in China, 2014].
abstract: OBJECTIVE
  To evaluate the hepatitis A vaccine coverage among 2-29 year olds and the reported incidence rates of hepatitis A, in China.
  
  
  METHODS
  Based on data from the national sero-survey on hepatitis B in 2014, information on hepatitis A vaccine immunization was collected and the coverage of hepatitis A vaccine was analyzed with SAS software (Version 9.4). Incidence data on hepatitis A was also collected from the National Notifiable Disease Reporting System between 2004 and 2014, and analyzed using the micro-software Excel 2007.
  
  
  RESULTS
  Totally, data involving 29 058 people aged 2-29 years were available for analysis and the overall hepatitis A vaccine coverage was 44.6%. The younger the age, the higher the coverage appeared. Among the 2-6 year and the 7-14 year olds, rates of hepatitis A vaccine coverage were 91.2% and 76.0% respectively. From 2004 to 2014, the incidence rates of hepatitis A in the whole population were declining, annually. The incidence rates showed continuously declining as 82.5%, 90.6%, 72.1% among children at the age groups of 2-6 years, 7-14 years and in the whole population, from 2007 to 2013.
  
  
  CONCLUSIONS
  After the inclusion of hepatitis A vaccine into the Expanded Programe on Immunization (EPI), the coverage of hepatitis A vaccine among the 2-6 year olds increased to over 90%, with no obvious difference between the urban and rural areas. Incidence of hepatitis A in the 2-6 year olds showed a more rapid decline than that in the whole population.
