Novel vaccine antigen to protect against pneumococcal diseases

My Ph.D. research is internationally recognized for discovery and testing of new protein molecule, Polyamine Transport Protein D (PotD), to immunize children against Streptococcus pneumoniae diseases. It is estimated that in 2000, about 14.5 million episodes of serious pneumococcal disease occurred, resulting in about 826 000 deaths in children aged 1-59 months (). My work has been independently corroborated by multiple academic and government researchers, and PotD is currently being used by agencies in Brazil (, ), China () and the Gates foundation/PATH (), to develop affordable vaccines for prevention of pneumococcal diseases. Prior efforts to use protein-based vaccines were not successful as they only stimulated human immune system, while immunization with PotD may also cripple the bacterial nutrient acquisition and virulence. In recognition of my contributions to public health, I was selected for the 2009 Raymond W. Sarber National Award from the American Society of Microbiology.
