Improving Health Outcomes in Inflammatory Diseases: From COVID-19 to Rheumatoid Arthritis - GSS 1.0 (3/6)

Prof. Samuel Essien-Baidoo is an Associate Professor in Laboratory Medicine at the University of Cape Coast, Ghana, and a Fellow of the West African Postgraduate College of Medical Laboratory Science. His research is dedicated to exploring the intricate interplay between natural and artificial determinants of adverse health outcomes, particularly in the context of infectious and non-infectious diseases. Away from research, Prof. Essien-Baidoo has a wealth of administrative experience, having served as the founding Head of the Department of Medical Laboratory Science and held many other positions at UCC, Ghana. He has also shown deep commitment to community service and mentorship by supporting and guiding student volunteers engaged in various initiatives, spanning livelihood empowerment, environmental sanitation, and reproductive health. In this episode, Prof. Essien-Baidoo shares highlights of his research exploring the link between vaginal microbes, the immune system, and the onset of cervical intraepithelial neoplasia (CIN) in Ghanaian women. Findings from this study will inform cervical cancer screening and management in at-risk women. Connect with him/learn more about his work here and across ⁠⁠LinkedIn⁠⁠, ⁠⁠X⁠⁠, ⁠and ⁠⁠ResearchGate⁠⁠.

Dr. Oghenebrume Wariri is a Clinical Research Fellow in Vaccines and Immunity at the MRC Unit The Gambia at LSHTM. His research focuses on vaccine epidemiology, particularly examining the performance of country-level immunization systems and investigating how broader demand- and supply-side factors influence the delivery and uptake of routine childhood vaccination in West Africa. Dr. Wariri received his Medical Degree (MBBS) from the University of Benin (Nigeria) and specialized as a Paediatrician after completing a six-year residency training program, earning a Fellowship of the West African College of Physicians. He obtained his MSc in Global Health as a fully-funded Chevening scholar from the University of Aberdeen, UK and has previously held a Wellcome Trust Global Health Clinical Research Training Fellowship at Imperial College London. His PhD at the London School of Hygiene and Tropical Medicine (LSHTM) investigates the burden, spatial pattern, and drivers of untimely routine childhood vaccination in The Gambia. Dr. Wariri sits on the five-member WHO National Verification Committee (NVC) for Measles and Rubella in The Gambia and is also a member of the Management Committee of the Vaccine Centre at LSHTM. He was the Principal Investigator of the recently concluded EDCTP-funded TIMELY study, which investigated the spatial pattern of untimely routine childhood vaccination in The Gambia and the 2023 African Visiting Fellow to the Office of Population Research (OPR) at Princeton University. In July 2023, Dr. Wariri was awarded the five-year Fogarty Emerging Global Leader award (K43) from the U.S. National Institutes of Health (NIH) to map zero-dose prevalence, delayed measles vaccination, and the risk of measles outbreaks in The Gambia. In this episode, we delve into his career journey, highlighting his contributions toward improving access to vaccines in children. Alongside providing updates on his recent award, Dr. Wariri also had a lot of nuggets to share with African scientists on collaborations and research translation.

Graduate Student Series (GSS) 1.0 (Episode 6 of 6) Kumba Seddu started her PhD journey at Johns Hopkins University where she investigated male and female immune differences to viral vaccines and infections. Her research added to the growing evidence that vaccinated females have greater antibody responses than males. This increased vaccine-induced antibody response in females is due to hormonal (estrogen) effects and sex chromosome (XX) effects. Now at Harvard Medical School, she is studying the gene expression and immune cell activation cascade upon interleukin-2 [IL-2] cytokine stimulation. IL-2 treatment has implications from infection to autoimmune diseases and cancer. She has won several awards including the U.S National Institute of Health Specialized Centers for Research Excellence award, the Delta Omega Honorary Society in Public Health award, and the Paul Farmer Honorary award. Kumba is passionate about equipping researchers and young leaders from low- and middle-income countries to end infectious diseases and solve global challenges. This goal drives her commitment to mentoring students around the world and to leading community solution-driven projects in her home country, Sierra Leone. In this episode, she shares her inspiring journey from Sierra Leone to the United States, where she's currently pursuing her PhD in the field of immunology [Kumba's current research explores immune responses to the cytokine, interleukin-2 (IL-2)]. As usual, we also get to hear her thoughts on the current state of immunology in Africa as well as approaches for advancing research in the field.

Abena Amoah (PhD) is the lead for the HypoVax Global Knowledge Hub based at Leiden University Center for Infectious Diseases of the Leiden University Medical Center, Leiden University, in the Netherlands. The knowledge hub is focused on understanding variations in vaccine responses across geographical areas and populations. It aims to address the central question of why weaker responses to some vaccines are seen in some regions compared to others and brings together researchers from around the world to make connections and form a strong network. Originally from Ghana, Dr. Amoah was born and raised in Southern Africa. She holds a PhD. in immunoepidemiology from the University of Leiden in the Netherlands, an MSc in epidemiology from the London School of Hygiene and Tropical Medicine, and a bachelor's degree in biological sciences from Mount Holyoke College, United States. She has also held post-doctoral positions at both the London School of Hygiene and Tropical Medicine based overseas in Malawi and Leiden University Medical Center. In this episode, we explored her research career starting from her earliest foray into addictive diseases in the US, through her relocation to Ghana, which led her into the field of immunology and, by extension, her current role. The crux of this episode is the promises the project she oversees at the HypoVax Global Knowledge Hub⁠ hold for Africa, especially in the context of vaccine development and distribution.

Chinedu Alphonsus Ugwu (PhD) holds a Doctor of Veterinary Medicine (DVM) with distinctions from the University of Ibadan, Nigeria, a Master of Science in Integrated Immunology from the University of Oxford, UK, and a Doctor of Philosophy in Veterinary Sciences from the University of Cambridge, UK. He specializes in translational immunology, vaccine, immunotherapeutic designs for pathogens, and one health approach to tackling disease outbreaks. He currently lectures in the Biological Sciences Department at Redeemer’s University, taking undergraduate and postgraduate classes in immunology, virology, bioethics, biosafety, and biological techniques. He also doubles as a post-doctoral research fellow at the African Centre of Excellence for Genomics of Infectious Disease (ACEGID), where he leads several projects. One such projects is a Biotechnology and Biological Science Research Council (BBSRC)-funded project on One Health and accelerating Vaccines for Ebola and Lassa Fever (OVEL). His research focuses on understanding how the immune system modulates the outcome of viral infections. By elucidating the correlates of protective immune response to viral infections such as Lassa fever virus, SARS-CoV-2, and other endemic viral diseases in West Africa, he aims to contribute to vaccine and therapeutic designs, diagnostics production, and informed public health policies for the diseases. This episode explored Dr. Ugwu's works on viral diseases with a specific focus on his recent publication which evaluated immune responses to the Lassa Fever Virus in survivors and exposed contacts of the disease.
