VALIDATE is an international network of Vaccine researchers who are focused on four pathogens that cause diseases that have significant impact on low and middle-income countries including tuberculosis, leishmaniasis, melioidosis and leprosy.

Our seminars highlight some of the important research being undertaken by our extensive community of researchers. We will put details of any upcoming seminars on this page.

Bernardo Villarreal-Ramos is VALIDATE Network Investigator and Professor of Immunology at the University of Aberystwyth and the Animal and Plant Health Agency (APHA), UK with a research focus on Tuberculosis, animal models, vaccines and T-cells.

Amanda Gibson is a VALIDATE Network Associate and Lecturer in Innate Immunology at Aberystwyth University whose research interests lie in underpinning early events required for establishing infection; the interaction between mycobacteria and host cells, particularly with the innate immune system at the point of recognition and uptake and initial responses leading to disease.

Associate Professor Hiro Goto is a VALIDATE Network Investigator based at the Universidade de Sao Paulo (USP), Brazil. Hiro's research focus is on immunopathology and diagnosis of leishmaniasis.

Eduardo Milton Ramos Sanchez is a VALIDATE Network Associate and Post-doctoral researcher presently working at the Institute of Tropical Medicine of Sao Paulo, USP, Brazil. Eduardo has been involved in purification and production of recombinant antigens for the development of serological tests for leishmaniasis and Malaria and vaccines for Bovine mastitis.

Speaker: Mary Burtnick is a Network Investigator and Associate Professor based in the University of Nevada, Reno School of Medicine. Mary has nearly two decades of experience working with pathogenic Burkholderia species and her current research focuses on identification of antigens expressed by Burkholderia pseudomallei that can be used to develop novel vaccines, diagnostics and immune assays to combat melioidosis.

Developing a vaccine for Melioidosis: Probing the protective immune response

Location: Online via Zoom.

Date: 30 June 2020

​​Time: 15:00 BST - 16:00


Prof Siobhán McClean is an Associate Professor at School of Biomolecular and Biomedical Science, UCD.  Prof McClean has a research interest in host pathogens associated with respiratory pathogens that cause opportunistic infections and in identifying vaccine antigens that are protective against Burkholderia pseudomallei.

Dr Julen Tomás Cortázar is a postdoctoral researcher at UCD. He is leading part of a project funded by Wellcome Trust agency to develop a vaccine against Melioidosis caused by the Gram-negative bacteria Burkholderia pseudomallei.

VALIDATE seminar - Developing a better vaccine against TB

This seminar took place 15 February 2019 and was led by Prof Helen McShane and Dr Rachel Tanner.

TB kills more people than any other infectious disease. The efficacy of the only available vaccine, BCG, is highly variable and lowest in high burden settings. The McShane group is developing novel TB vaccine candidates by identifying novel antigenic targets and exploring novel routes of immunization.

TB vaccine development is challenging given the lack of defined immunological correlates of protection. Class II restricted T cells are critical for protective immunity but may not be sufficient. Dr Tanner provided an update on functional mycobacterial growth inhibition assays and on a role for antibodies in protective immunity.

zelmer fletcher seminar

This seminar took place on the 6 December 2017 at LSHTM and was led by Dr Andrea Zelmer and Dr Helen Fletcher, LSHTM.

Immune correlates of risk of TB disease have recently been identified in human clinical trials.  These correlates indicate that, years before TB disease develops, there is alteration in the host-immune environment which is associated with risk of TB disease. Perhaps these alterations render the immune environment permissive to mycobacterial infection or increased growth, or perhaps they reduce the efficacy of the BCG vaccine?  Back translation of immune correlates of risk into animal models will enable us to address these questions and model the immune response of those individuals at greatest risk of TB disease.
