It was such an enlightening and relevant course!!! So much to learn on Vaccine Preventable Diseases (VPDs), vaccine development and research methods among the numerous content delivered. My truly humbling experience out of many was taking part in the Oxford AstraZeneca vaccine clinical trials The knowledge and skills will be translated into reducing VPDs associated morbidity and mortality in Africa and the world. Many thanks to all the organisers- Wits-ALIVE consortium, presenters and all participants. I would like to recognise the funders, Bill & Melinda Gates Foundation (BMGF).
