Haemophilus influenzae type b (Hib) vaccination and uptake predictors in Northern Ireland
1Department of Health Strategy and Primary Care, Southern Health and Social Services Board, Craigavon, Northern Ireland.
Insights
High Haemophilus influenzae type b (Hib) vaccine uptake (over 97%) was observed. Factors like maternal smoking and having multiple younger siblings were associated with lower Hib vaccination rates.
Area of Science:
- Pediatrics
- Public Health
- Epidemiology
Background:
- Haemophilus influenzae type b (Hib) is a significant cause of bacterial meningitis in young children.
- Vaccination is crucial for preventing Hib infections and their severe complications.
Purpose of the Study:
- To identify factors influencing the uptake of the Haemophilus influenzae type b (Hib) vaccine.
- To calculate the odds of non-completion of Hib vaccination based on specific demographic and social factors.
Main Methods:
- A case-control study design was employed.
- Data were collected from the child health computer system for infants born between January 1 and June 30, 1993, within a specific health board in Northern Ireland.
- Cases were defined as unvaccinated children, and controls as vaccinated children.
Main Results:
- Overall Hib vaccination uptake exceeded 97%.
- Children born to mothers who smoked showed a lower likelihood of being vaccinated.
- Children with two or more younger siblings were also less likely to complete their Hib vaccination.
Conclusions:
- Despite high overall vaccination rates, specific maternal and familial factors are associated with incomplete Hib vaccination.
- Targeted interventions may be necessary for groups identified as having lower vaccination uptake.
Abstract:
In order to study selected factors affecting the uptake of Haemophilus influenzae type b (Hib) vaccine a case control study was undertaken in residents of the Southern Health and Social Services Board in Northern Ireland. Standard data from the child health computer system were used. Residents in the catchment area of the health board born between 1 January and 30 June 1993 were defined as cases (unvaccinated) and controls (vaccinated). The uptake of Hib vaccination and odds ratios for factors associated with non-completion of vaccination were calculated. Overall uptake of Hib vaccination exceeded 97%. Children of mothers who smoked or children who had two or more younger siblings were less likely to have been vaccinated.
