Navigating the Challenges of Implementing Tuberculosis Research During COVID-19 Pandemic: Insights from the Pediatric Tuberculosis-Moderate Acute Malnutrition Study.

Clinical research involving children presents significant challenges due to physiological, ethical, regulatory, and practical considerations unique to this vulnerable population. These intrinsic challenges were amplified during the COVID-19 pandemic, which substantially disrupted pediatric research and child health services. The pandemic exposed critical ethical, operational, and communicative tensions, especially with respect to informed consent, caregiver trust, and safe research implementation. Examining these intersecting challenges can improve and strengthen pediatric research to remain ethically robust and child-centred in the event of future public health crises.
