Infant immunisation coverage in Flanders, Belgium, is monitored through repeated coverage surveys. With the increased use of Vaccinnet, the web-based ordering system for vaccines in Flanders set up in 2004 and linked to an immunisation register, this database could become an alternative to quickly estimate vaccination coverage. To evaluate its current(More)
To assess changes in infant vaccination coverage in Flanders since 1999, an EPI-survey was performed in 2005. The parents of 1354 children aged 18-24 months were interviewed at home and the vaccination documents were checked. Several factors possibly related to vaccination status were examined with parametric and non-parametric methods. The coverage rate of(More)
WHO-Europe's goal is to eliminate measles and rubella by 2010 which will require a coverage rate of 95% for both MMR-vaccine doses. Belgian recommendations include a first MMR vaccine at 12 months and a second at 10-12 years of age. To survey MMR vaccination coverage, EPI two-stage random cluster samples of 1,500 toddlers (18-24 months of age), 900 primary(More)
OBJECTIVE The objective of this study was to measure the coverage and influencing determinants of hepatitis B virus, measles-mumps-rubella, and Meningococcus serogroup C vaccination in 14-year-old adolescents in Flanders, Belgium, in 2005. METHODS A total of 1500 adolescents who were born in 1991 and were living in Flanders were selected with a 2-stage(More)
Influenza vaccination is less effective in the elderly compared to the young. Studies that have attempted to identify immune parameters correlating with satisfactory vaccine responses have yielded inconclusive results. Here, we correlate the distribution of different circulating CD4+ and CD8+ T-cell phenotypes with the humoral response to vaccination with(More)
Achieving high vaccination coverage is a necessary, but not a sufficient indicator of the quality of a vaccination programme, in terms of control and prevention of childhood infectious diseases. For optimal protection of infants, timeliness of vaccination is increasingly recognized as another important target. The aim of this study was to assess the(More)
Quantitative information on parents' preferences regarding multiple vaccine injections and on work-loss due to vaccination is important to guide decision making on the use of combination vaccines for universal vaccination. Our survey in families of 1347 toddlers (18 -- 24 months) and 1315 adolescents residing in Flanders, Belgium, revealed common attitudes(More)
OBJECTIVE To standardize serological surveillance to compare rubella susceptibility in Australia and 16 European countries, and measure progress towards international disease-control targets. METHODS Between 1996 and 2004, representative serum banks were established in 17 countries by collecting residual sera or community sampling. Serum banks were tested(More)
OBJECTIVE To evaluate immunogenicity and reactogenicity of primary vaccination with reduced-antigen-content diphtheria-tetanus-acellular pertussis (dTpa) or dTpa-inactivated poliovirus (dTpa-IPV) vaccine compared to diphtheria-tetanus-toxoid vaccines (Td) in adults > or = 40 years of age without diphtheria or tetanus vaccination for 20 years or with an(More)
Mumps outbreaks have recently been recorded in a number of highly vaccinated populations. We related seroprevalence, epidemiological and vaccination data from 18 European countries participating in The European Sero-Epidemiology Network (ESEN) to their risk of mumps outbreaks in order to inform vaccination strategies. Samples from national population serum(More)
