Biography

Patrick K Owiafe been in charge of running the lab for almost 14 years and have worked with 4 fantastic line managers.Patrick K Owiafe acquired an MSc in Immunology and Immunogenetics by distance learning with the University of Manchester. In addition, all the vaccine trials that I have been part of have been successful. These include the MVA-85A TB vaccine trial, GSK M72/ASO1E and GSK Pneumococcal protein vaccine trial which is just about winding up.
