December 17, 2020 – SEOUL, South Korea – Vi-DT typhoid conjugate vaccine, developed jointly by the International Vaccine Institute (IVI) and SK bioscience, has met the primary endpoints in a phase III study in Nepal. The primary endpoints were based on immune non-inferiority with the WHO-prequalified typhoid conjugate vaccine, Typbar-TCV®, in terms of serconversion rate, which confirms the new candidate TCV induces an immune response that is not inferior to Typbar-TCV®.
Three different production lots of vaccine were administered in the clinical trial, and the analysis also shows that these different batches were similar in immunogenicity. Lot-to-lot consistency in manufacturing is an important requirement to ensure the quality of Vi-DT.
In addition to immune non-inferiority, the Vi-DT vaccine was also shown to be safe in all 1,350 participants ranging in age from 6 months to 45 years.
This study is a significant milestone in an effort to license Vi-DT TCV. Another phase III study is nearing completion in the Philippines and SK bioscience plans to submit a Marketing Authorization request to the Korean Ministry of Food & Drug Safety in January 2021. After the Ministry of Food and Drug Safety approves the vaccine, it will be submitted for pre-qualification review at the World Health Organization. WHO pre-qualification is necessary for a vaccine to be sold to United Nations agencies responsible for vaccine purchases.
“It was a challenging project to get the sites in Nepal ready,” said Dr. Tarun Saluja, MD, the project lead of this study. “However, with the help of the authorities in Nepal and our collaborators, we managed to complete this study within timeline and with quality.”
“These data are the culmination of 10 years of work at IVI,” said Dr. Sushant Sahastrabuddhe, MD, Director of IVI’s Typhoid Program. “With the successful initial results from phase I and II studies in the Philippines, this phase III study was critical to make sure Vi-DT vaccine completes the regulatory milestones for use in endemic countries. We are quite pleased with the results and plan to publish them soon.”
“With this encouraging data from the Phase 3 trial, we have taken a step closer to the commercialization of the vaccine,” said Jae-yong Ahn, CEO of SK bioscience. “In collaboration with IVI and other partners, we will develop a vaccine that is universally accessible to help free children in developing countries from typhoid.”
Vi-DT was developed at IVI and its technology was transferred in 2013 to SK bioscience in South Korea for manufacturing and commercialization. A Phase I safety trial of Vi-DT was first conducted in the Philippines in volunteers aged 2-45 years and showed that the vaccine was safe and immunogenic four weeks after first dose. Following the successful completion of a Phase II trial with infants under 2 years, large-scale Phase III studies with a single-dose of Vi-DT started in the Philippines and Nepal this year.

About typhoid
Typhoid fever is an invasive water-borne bacterial infection caused by Salmonella enterica serovar Typhi (S. Typhi) presenting with mild to severe symptoms and even resulting in death. Typhoid is most often contracted through ingestion of food or drink contaminated by bacteria shed by infected people. It is usually characterized by fever, headache, constipation, and malaise, though diagnosis can be difficult due to symptoms common to other febrile illnesses. Figures for burden of disease vary due to this difficulty, however the World Health Organization estimates that 128,000-161,000 people die every year from typhoid fever with 11-21 million annual cases.[1] Typhoid surveillance studies report that a quarter to more than half of all invasive cases are found in children under 5.[2]

A total of 57 participants from Bangladesh, Nepal, Uganda, and Malawi attended the webinar, together with those from IVI-RADAAR and EVIPNet/WHO.
Webinar 4 began with the ‘Feedback on preparatory work’ outlined in Webinar 3, which was to:
Dr Fadi El-Jardali from the American University of Beirut updated participants on the progress of the four countries including: on the topics selected (Uganda on irrational antibiotic use; Nepal on AMR National Action Plan (NAP) implementation [adjudged to be more about the solution than the problem]; Malawi on the utilization of AMR evidence generated at facility/national level and translation into policy [also more about the solution than the problem]; and Bangladesh, which had not yet been reviewed. The review also included country search strategies. The feedback included questions from participants.
The webinar then focused on the next (of the 15) training sessions:
Session 9. Preparing the EBPs: clarifying and framing the problem including:
Knowledge Translation (KT). Which facilitates the process of translating research into policy and action; and KT products which allow evidence generated from systematic reviews – the basic units of KT – to be packaged in a user-friendly format, written in clear language, and with key messages to increase the likelihood of adoption by policy-makers, and resonance among different target audiences. The use of systematic reviews enable policy-makers to scan large bodies of research evidence to address key features of any policy issue of interest.
– Problem statement: A policy problem that summarizes the best available evidence to clarify the size and nature of the problem and its underlying causes.
– Options or elements: Three or more viable policy and programmatic options described.
– Implementation considerations: Potential barriers to implementing the options/elements and strategies for addressing those.
The EBP does not provide recommendations for action.
The remainder of Webinar 4 featured the Group work exercise facilitated by Racha Fadlallah from K2P Lebanon (and support from EVIPNet). The group work comprised four groups – one for each country (including representatives from WHO country offices, and observers from EVIP/RADAAR) – with the aim:

Webinar 3 began with the ‘Feedback on preparatory work’ outlined in Webinar 2, which was to:
Fadi El-Jardali from the American University in Beirut updated participants on the progress of the four countries and provided further guidance for countries on completing these two crucial stages. Malawi was used as an example applicable to other countries, in terms of structuring thinking in relation to identifying the issue, the political context, what has already been done in terms of AMR, what is missing and why, and stakeholder mapping. Country participants summarised their experiences. The feedback ended with a discussion on the priority areas of focus for the Evidence Brief for Policy (EBP), with updates from countries.
Following feedback reporting, the webinar focused on the next two (of 15) training sessions:
Session 7. Designing search strategies to identify and access research evidence on priority topics including: the importance of effective searches (6,500 medical articles published daily); the use of ‘Boolean Operators (e.g., And, Or, Not); identification of search terms; building a search strategy, including formulating the question/issue, choosing appropriate databases, dividing the question/issue into 2 or 3 concepts, generating search terms for each concept, and combining concepts – and search terms within concepts – using Boolean operators; and validating/documenting the search.
An example of a ‘search’ template was presented, and which participants would complete in the group work at the end of the webinar. The template included: the Problem/Issue being addressed, the Options, the Concepts, the Search terms for each concept, and Combining concepts using Boolean operators
The importance of collecting the best available evidence for EBPs was stressed: local evidence and global research evidence from systematic reviews. Guidance was provided on where to search for such information, including local and national databases, websites of relevant organisations, search engines, ‘grey’ literature, and systematic reviews.
Session 8: Understanding the role of systematic reviews in influencing policy decisions including: the Concept of a systematic review; key databases to search – and how to search – for reviews (e.g., Health Systems Evidence, Cochrane, PubMed); a live demonstration of a search on Health Systems Evidence and PubMed databases; and assessing the quality of reviews (e.g., using AMSTAR).
The remainder of Webinar 3 featured the Group work exercise facilitated by Racha Fadlallah and
Lama Bou Karroum from K2P Lebanon (with support from EVIPNet). The group work was comprised of four groups
– one for each country (including representatives from WHO country offices, with observers from EVIP/RADAAR) – with the aim: To develop a search strategy and search key databases for systematic reviews.
A template was provided by EVIP facilitators (based on the presentation from Session 7) with sections for completion by country groups as follows: the Topic/Issue being addressed, the Concepts, the Search terms for each concept, Combining concepts using Boolean operators, and the Databases searched.
Date:Thursday, 18 August 2022
Objectives:
A total of 65 participants from Bangladesh, Nepal, Uganda, and Malawi attended the webinar, together with those from IVI-RADAAR and WHO.
After a brief introduction, Webinar 2 began with ‘Feedback on preparatory work’ outlined in Webinar 1:
The EBP Team is responsible for developing the EBP and conducting key informant interviews (KIIs), hence an appropriate mixture of expertise is key to a successful team, including members with experience in: methods of writing an EBP; administration; evidence search, appraisal and synthesis; technical expertise on the topic being addressed in the EBP; and communication. Each country must also appoint an EBP steering committee to support the EBP development process, comprising: 4-6 multisectoral, multidisciplinary and high-level stakeholders from government/policy-makers/researchers knowledgeable in the topic and able to contribute to the development of the EBP for AMR.
Each of the four countries reported briefly on the steps taken to form the Core Team, Steering Committee, and in identifying AMR stakeholders (some countries had also informed RADAAR/EVIP prior to the Webinar via email).
Following reporting, the Webinar focused on the next two (of 15) training sessions:
Session 5. Understanding the political and health system and outlining key areas to keep in mind when mapping the policy and political context including: the importance of context-specific and actionable evidence, in particular the political/policy context (e.g., characteristics of government structures, civil service – and interests of – policy-making stakeholders, societal values and external factors, such as social and economic); and health system context (e.g., evidence on health system inputs, processes, and outputs and the analysis of how they combine to produce outcomes, such as – the WHO defined – service delivery, health workforce, information, medical technologies, finance, and leadership/governance).
Session 6:Stakeholder mapping including: on stakeholder interests, i.e., concerns over how a policy may impact them; their positions, i.e., degree of agreement or disagreement with the policy; and their power, i.e., capacity to influence policy. The steps in stakeholder mapping include: defining the goal and implications of the proposed policy change; listing interest groups involved in the issue; categorizing stakeholders according to their influence and power over, and level of interest in the issue; determining a strategy to engage relevant stakeholders; conducting KIIs; and presenting stakeholder analysis.
Stakeholders identified include: decision-/policy-makers (e.g., ministries, government agencies, parliamentarians, municipalities); influencers (e.g., NGOs/CSOs, religious leaders, media, private sector); and the public (e.g., those affected by AMR).
A case example from Ghana was presented to highlight the steps in stakeholder mapping.
Webinar 2 concluded with a Group work exercise (with support from EVIPNet/K2P)
Group work was comprised of four groups – one for each country (including representatives from WHO country offices) – with the aim of:
A template was provided by facilitators with nine questions to capture the above details including: the issue; progress made in addressing the issue; previous related policies/laws/regulations; whether the issue is on the government agenda; windows of opportunity; requirements to reach the policy objective; how laws/regulations are implemented to this purpose; stakeholders involved; and the power interplay among/between stakeholders. The questions provided background information to enable completion of full ‘Stakeholder Mapping’ template (including stakeholder, description, name, power, interest).
