Pertussis: should we immunise neurologically disabled and developmentally delayed children?
Insights
Children with neurological disorders have lower pertussis immunization rates. Valid reasons for non-immunization were higher, with pediatricians often advising against pertussis vaccines, warranting a review of current medical advice.
Area of Science:
- Pediatrics
- Neurology
- Immunology
Background:
- Pertussis (whooping cough) immunization is crucial for child health.
- Concerns exist regarding the safety of pertussis vaccines in children with pre-existing neurological conditions.
- Understanding immunization rates and reasons for non-compliance is vital for public health.
Purpose of the Study:
- To compare pertussis immunization rates in children with neurological disorders versus healthy controls.
- To investigate the reasons for non-immunization in children with neurological disorders.
- To assess the validity of non-immunization reasons based on official health guidelines.
Main Methods:
- A case-control study involving 400 children with neurological disorders and 400 age-matched healthy controls.
- Data collection on immunization status, reasons for non-immunization, and medical advice received.
- Analysis of immunization rates and trends over time, particularly post-1975.
Main Results:
- Children with neurological disorders had significantly lower pertussis immunization rates compared to controls (p<0.01).
- Immunization rates declined sharply for both groups after 1975.
- Cerebral palsy patients exhibited the lowest immunization rate (19%) and highest rate of valid non-immunization reasons (63%).
- Paediatricians advised against pertussis immunization in 32% of the study group versus 2% of controls.
Conclusions:
- The risk of serious neurological handicap following pertussis immunization is minimal.
- There is limited evidence that underlying neurological disease increases risks associated with pertussis vaccination.
- Current pediatric advice regarding pertussis immunization in children with neurological disorders may require re-evaluation.
Abstract:
A total of 400 children with neurological disorders were studied to ascertain whether they had been immunised against pertussis, the reasons for non-immunisation, and the "validity" of these reasons, as judged by interpretation of the recommendations of the Department of Health and Social Security. The results for this group were compared with those for a group of 400 aged matched controls. The study group had a significantly lower rate of immunisation than controls (p less than 0.01); rates for both groups fell sharply after 1975. A total of 192 study patients and 186 controls were not immunised. Those children with cerebral palsy had the lowest rate of immunisation (19%) and the highest number of valid reasons for non-immunisation (63%). Paediatricians apparently advised against immunisation in 61 (32%) of the index group but in only four (2%) of the controls. The risk of serious neurological handicap after pertussis immunisation is small and there is little evidence to support the view that underlying neurological disease predisposes a child to increased risk. The advice currently given by paediatricians may need to be reconsidered.
