About this study

Official title: Measurement of the Changes in Hepatitis B Immunization Coverage in Infants, and the Acceptability Thereof, Before Reimbursement, Then During the Three Years After Reimbursement of InfanrixHexa® in France, Among the General Population

The present study is conducted in order to assess the acceptability of Hepatitis B vaccination in French general population before and after reimbursement of the paediatric vaccine InfanrixHexa. Four measurements are planned, first before reimbursement and the others at year 1, 2 and 3 after reimbursement.

Read the detailed description

The present study aims to evaluate the changes in Hepatitis B immunization coverage and the acceptability thereof among parents, in the general population. This is a national, prospective, epidemiological study, comprising four measurement time-points over a three-year period, (T1 in 2009, T2 in 2010, T3 in 2011, and T4 in 2012) in order to cover the period prior to the introduction of InfanrixHexa® reimbursement, the transition period, and the period following reimbursement of the vaccine. The periods between each data collection time-point will be identical, lasting a year. Two age groups will be investigated at each data collection time-point: 12-15 months and 24-27 months, thus providing measurements before/after reimbursement.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of infants receiving Hepatitis B vaccination.

    Measured: 4 years

Secondary outcomes (2)
  1. Evaluation of the immunization coverage levels by other vaccines.

    The vaccination coverage by other vaccines will be described for each time point (i.e. at the initial time point, and at the years 1, 2 and 3 time points).

    Measured: 4 years

  2. Acceptability of vaccinating against Hepatitis B.

    Acceptability of vaccinating against hepatitis B will be evaluated via assessment of the variation of this acceptability amongst parents categorised as "accepting", using their responses to a semi-qualitative questionnaire about vaccination.

    Measured: 4 Years
