Seminars

 

VALIDATE is an international network of vaccine researchers focused on four pathogens causing diseases with significant impact on low and middle-income countries: 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.

"A Vaccine for...?" Seminar Series

In VALIDATE's "A Vaccine for" seminar series, leading experts will provide an overview of the state of vaccine research for VAIDATE’s focus pathogens. Each seminar will be open to all and will provide an excellent opportunity for VALIDATE members and researchers to learn about pathogens and vaccines outside of their usual research focus.

 

 

A Vaccine for Leprosy?

A Vaccine for Leprosy? - 28 June 2022

This seminar will be the third in our "A Vaccine for" seminar series, in which leading experts will provide an overview of the state of vaccine research for VAIDATE’s focus pathogens. In "A Vaccine for Leprosy?", Dr Khushboo Borah and Dr Chyntia Carolina Díaz Acosta will discuss the prospects for a vaccine for Leprosy, the disease caused by Mycobacteria Leprae of which there are still over 200,000 new cases of diagnosed every year.

The seminar is open to everyone (including non-members), but will be especially interesting to vaccine researchers who do not study leprosy.

The Event will take place at 16:00 BST, 28 June 2022 and you can register on the event webpage - www.validate-network.org/event/a-vaccine-for-leprosy

About the Seminar: The seminar took place at 10:00 GMT, 30 November 2021

BCG is the most studied vaccine and holds promise. Several studies indicate that BCG confers some protection against leprosy. In this talk, Dr Yumi Maeda, of the Leprosy Research Center National Tokyo Institute of Infectious Diseases, Japan, discusses how her team constructed a recombinant BCG that secretes Major Membrane Protein-II of M. leprae, and found that it was effective in inhibiting the growth of M. leprae in mice footpads. Studies are underway to produce BCG that is stable and can be used for large scale preparation.

Detection of leprosy is also necessary for early treatment. From the analysis of the genomic sequence, specific genes coding for antigens of leprosy were selected for evaluating the antibodies in the sera of patients, and user-friendly tools are also being developed.

COVID has provided a stark example of pathogenic mutation. The variation of the impact of infection on the population similarly shows that human responses are variable. This highlights a key need in vaccinology of identifying and developing technologies that can address diversity whilst maintaining safety and achieving cost-effectively. In this session, Graham Clarke explores the options and particularly highlight ImmBio’s approach, exemplified by its lead development against Streptococcus pneumoniae, a good example of a bacteria in circulation with a wide array of genotypes. Whilst there are products available providing good protection against specific serotypes, as defined by the polysaccharide capsule used in the current class of vaccines, ImmBio’s focus is a multiple-protein approach. A new approach raises new regulatory and manufacturing challenges but again drawing on COVID experience, vaccinology may be able to able to benefit from a paradigm shift in addressing risk and benefit, enhancing the attractiveness of investing in new vaccines.

​​​​​​Speaker: Graham Clarke is ImmBio’s Chair and previously its CEO. Originally a biophysicist, he has held senior-level positions including at SmithKline Beecham, GSK and GE Healthcare. He is now a non-executive on a number of boards, including the UK’s Medicine Discovery Catapult and NHS Health Research Authority. He has also been a member of the UK government’s COVID therapeutic task force.

In an upcoming publication in Nature Biotechnology, Dr Sheila Keating and her team have demonstrated the technology to capture entire immune repertoires from infected or vaccinated individuals, to be used to treat difficult to treat infections - and have demonstrated this work with COVID and respiratory bacterial infections. In this talk, Dr Sheila Keating described the technology and will mapped out potential pathways for developing passive immune therapeutics that will not only treat but also help to prime immune responses to protect against future infections. Location: Online via Microsoft Teams ​​​​​​

Speaker:

Dr Sheila Keating is a VALIDATE Network Investigator Adjunct Associate Professor at GigaGen and the University California San Francisco. Over the past 15 years, Sheila's work has focused on understanding cellular and humoral immune responses to vaccines and infectious diseases and, more recently, has focused on using high throughput immune assays to measure biomarkers of immune response or pathology in a number of studies ranging from HIV, HCV, HBV vaccine breakthrough, Chagas, West Nile Virus, cardiovascular disease, neuropathology and many other areas.

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.
