Abstract:
Influenza A virus (IAV) poses a constant worldwide threat to human health. Although conventional vaccines are available, their protective efficacy is type- or strain-specific, and their production is time-consuming. For the control of an influenza pandemic in particular, agents that are immediately effective against a wide range of virus variants should be developed. Although pretreatment of various Toll-like receptor (TLR) ligands have already been reported to be effective in the defense against subsequent IAV infection, the efficacy was limited to specific subtypes, and safety concerns were also raised. In this study, we investigated the protective effect of an attenuated bacterial outer membrane vesicle, harboring modified lipid A moiety of lipopolysaccharide (fmOMV) against IAV infection, and the underlying mechanisms. Administration of fmOMV conferred significant protection against a lethal dose of pandemic H1N1, PR8, H5N2, and highly pathogenic H5N1 viruses; this broad antiviral activity was dependent on macrophages but independent of neutrophils. fmOMV induced recruitment and activation of macrophages, and elicited type I IFNs. Intriguingly, fmOMV showed a more significant protective effect than other TLR ligands tested in previous reports, without exhibiting any adverse effects. These results show the potential of fmOMV as a prophylactic agent for the defense against influenza virus infection.

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.

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).
