Brief summary
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.
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.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Proportion of infants receiving Hepatitis B vaccination. | 4 years |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Evaluation of the immunization coverage levels by other vaccines. | 4 years | 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). |
| Acceptability of vaccinating against Hepatitis B. | 4 Years | 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. |
