Brief Summary:

The purpose of this study is to determine

  1. vaccination coverage of recommended vaccines (routine childhood vaccines and vaccines against seasonal flu and pneumococci) in children with chronic diseases (allergy, cystic fibrosis, diabetes mellitus type 1, congenital heart disease, immunocompromised and solid organ transplant patients)
  2. the level of protection against measles, mumps, rubella and pertussis in children with chronic diseases.
  3. vaccination coverage of recommended vaccines (diphtheria, tetanus, pertussis and vaccines against seasonal flu and pneumococci) in adults with chronic diseases (nephropathy, diabetes mellitus, COPD, heart failure, HIV and solid organ transplant patients)
  4. the level of protection against diphtheria, tetanus and pertussis in adults with chronic diseases.

Group/Cohort
Pediatric chronically ill patients

Through a questionnaire parents of chronically ill patients will be asked about the vaccination status of all recommended vaccines of their child. Also questions on disease, therapy and sociodemographic factors that can influence vaccination coverage will be asked.

A blood sample to determine antibodies against measles, mumps, rubella and pertussis will be drawn from children who consent to sampling.

The following groups of patients will be questioned: diabetes, allergy, congenital heart disease, cystic fibrosis, immunodeficiency and transplant patients, cancer patients.

Adult chronically ill patients

Through a questionnaire chronically ill patients will be asked about their vaccination status of diphtheria, tetanus,pertussis, flu, pneumococcal and hepatitis B vaccine(s). Also questions on disease, therapy and sociodemographic factors that can influence vaccination coverage will be asked.

A blood sample to determine antibodies against diphtheria, tetanus and pertussis will be drawn.

The following groups of patients will be questioned: diabetes, chronic kidney disease, heart failure, COPD, immunodeficiency and transplant patients, HSCT patients.




Primary Outcome Measures :
  1. Proportion of pediatric chronically ill patients correctly vaccinated with the hexavalent (DTaP-IPV-Hib-HBV), pneumococcal, rotavirus, MMR and MenC vaccine according to the Belgian recommended vaccination schedule. [ Time Frame: 5 years ]
    number of patients vaccinated compared to the entire group

  2. Proportion of adult chronically ill patients correctly vaccinated diphtheria, tetanus, pneumococci, hepatitis B and influenza according to Belgian recommended vaccination schedule [ Time Frame: 5 years ]
    number of patients vaccinated compared to the entire group


Secondary Outcome Measures :
  1. Proportion of pediatric patients with antibodies against measles, mumps, rubella, diphtheria, tetanus and pertussis in children included in the study and who provided a blood sample [ Time Frame: 5 years ]
    Determination of antibodies against measles, mumps, rubella and pertussis

  2. Proportion of adult patients with antibodies against diphtheria, tetanus and pertussis. [ Time Frame: 5 years ]
    Determination of antibodies against diphtheria, tetanus and pertussis
