Variability in immunization guidelines in children before and after lung transplantation

Area of Science:

• Pediatric Pulmonology
• Transplant Immunology
• Infectious Diseases

Background:

• Lung transplant candidates and recipients face a high risk of vaccine-preventable diseases.
• Existing vaccination and monitoring guidelines for pediatric lung transplant recipients are not well-established.

Purpose of the Study:

• To assess current vaccination and monitoring practices in pediatric lung transplant centers.
• To identify inconsistencies in pre- and post-transplant immunization strategies.

Main Methods:

• A self-administered questionnaire was distributed to 18 international pediatric lung transplant centers.
• 16 centers (89%) responded, providing data on their vaccination and monitoring protocols.

Main Results:

• National guidelines are followed pre-transplant, but only 11 centers have standardized post-transplant guidelines.
• Vaccine administration shifts from primary care physicians pre-transplant to transplant centers post-transplant.
• Monitoring of vaccine response is inconsistent, particularly post-transplant, with Hepatitis B being an exception.

Conclusions:

• Current vaccination practices in pediatric lung transplant centers are heterogeneous.
• There is a need for standardized guidelines and further research on vaccine efficacy in this vulnerable population.
