Mainga Hamaluba's responsibilities include providing leadership and coordination for clinical research and trials as well as monitoring, project management, database support and sponsorship for KWTRP investigator-led trials. She trained as a Pediatrician in Oxford and first started working in clinical trials over 15 years ago. Her research career started in Oxford followed by a 6-month Wellcome Trust visiting fellowship to the KEMRI-Wellcome Trust programme in 2006 and a return to Kenya in 2016. Her work in Kathmandu, Nepal and Oxfordshire focused on the population biology and vaccinology of Streptococcus pneumoniae in pre-school children. With a team of Nepali scientists, they conducted a vaccine trial in infants which informed and led to the introduction of the 10-valent pneumococcal conjugate vaccination schedule in Nepalese infants. Her research interests continue focus on vaccine and translational research in pediatric and neonatal care at KEMRI-Wellcome. She is fortunate to work with a group of leading scientists in the department and across the programme where they take a multi-disciplinary approach to improving child health and influencing policy.
