Mini-Seminar Implications of Israel's aggressive third dose �vaccine program

David O’ConnorProfessor of pathology and laboratory medicine, �University of Wisconsin

Israel began an aggressive COVID-19 immunization program before most other countries. Consequently, they were among the first to observe waning immunity. This prompted Israel to begin an ambitious real-world experiment to provide third doses of the Pfizer/BioNTech vaccine to those who were initially vaccinated at least five months previously. The early results show dramatic protection from both severe illness and mild cases among older individuals who were the first to receive the vaccine. In this presentation I will summarize the Israeli data and discuss why I think other countries including the US should implement similar programs as soon as possible.

Mini-SeminarAir surveillance for respiratory pathogens in �Dane County communities

Shelby O’ConnorProfessor of pathology and laboratory medicine, �University of Wisconsin

The COVID-19 pandemic has highlighted how underprepared our community is to detect circulating respiratory viruses. Predictive warning systems for these viruses are needed. For the past several months, we have been piloting Thermo AerosolSense air samplers in University, hospital, and other community settings. We have detected SARS-CoV-2 genetic material in air samples collected at many of these sites. In the future, we propose adapting this system for widespread use in K-12 schools to support ongoing mitigation strategies and provide additional virus detection methods for school communities.

Requests for Input/Suggestions

  

 

We would like the subgroup leads to prepare brief presentations for the Thursday meetings, please let us know when you would like to present

Ideas/help for publicising our Thursday mini-seminars more effectively and for speakers to invite

Suggestions for agenda items and approaches to organizing the Steering Committee Meetings more effectively

There have also been a number of requests for more explicit statements of goals and tasks from the WG leadership, we would appreciate your suggestions

Mini-SeminarOptimizing predictive models to prioritize viral discovery�in zoonotic reservoirs

Daniel BeckerUniversity of Oklahoma

Identifying and monitoring the wildlife reservoirs of novel zoonotic viruses remains logistically challenging and costly. Statistical models can be used to guide sampling prioritization, but predictions from any given model may be highly uncertain; moreover, systematic model validation is rare, and the drivers of model performance are consequently under-documented. Here, we use bat hosts of betacoronaviruses as a case study for the data-driven process of comparing and validating predictive models of likely reservoir hosts. In the first quarter of 2020, we generated an ensemble of eight statistical models that predict host-virus associations and developed priority sampling recommendations for potential bat reservoirs. Over a year, we tracked the discovery of 40 new bat hosts of betacoronaviruses, validated initial predictions, and dynamically updated our analytic pipeline. We find that ecological trait-based models perform extremely well at predicting these novel hosts, whereas network methods consistently perform roughly as well or worse than expected at random. These findings illustrate the importance of ensembling as a buffer against variation in model quality and highlight the value of including host ecology in predictive models. Our revised models show improved performance and predict over 400 bat species globally that could be undetected hosts of betacoronaviruses. Although 20 species of rhinolophid bats are known to be the primary reservoir of SARS-like viruses, we find at least three-fourths of plausible betacoronavirus reservoirs in this bat genus might still be undetected. Our study is the first to show via systematic validation that machine learning models can help optimize wildlife sampling for undiscovered viruses and illustrates how such approaches are best implemented through a dynamic process of prediction, data collection, validation, and updating. Lastly, we discuss next steps to systematically integrate within-host data streams into future modeling efforts.

Mini-SeminarQuantitative Modeling and Simulation to Drive Critical Decisions from Research through Clinical Trials

John Burke

CEO, President, and Co-founder, Applied BioMath

Quantitative Systems Pharmacology (QSP) is a mathematical modeling and engineering approach that aims to quantitatively integrate knowledge about therapeutics with an understanding of its mechanism of action in the context of human disease mechanisms.

Several examples will be shown which highlight QSP efforts to accelerate the discovery and development of best-in-class therapeutics and impact critical decisions, in the continuum from preclinical exploration to clinical research

Have you made new research contacts or collaborations based on the Viral Pandemics working group?

  • New collaborations that come out of this working group is an important metric of our success.

  • If you have new collaborations could you let the WG leads know?
    • co-writing a paper?
    • preparing a grant proposal?
    • preparing a teaching or modeling resource?
    • simply extensive discussions?

Charge to subgroups�(review):

Deliverable: White paper on the subgroup focus areas.�Due date: February 26, 2021

Steps to be taken:

  1. Subgroup lead(s) write one or two paragraphs on the topic of the subgroup and the main problems to be focused on. Due to working group leads: January 17
  2. Email to all subgroup members with this description and call for an initial meeting (if not happened yet) on or before January 26. Bruce can help with address lists and scheduling.
  3. At the initial meeting, discussion of the main topics of a white paper that surveys the subgroup topic and lists major problems and potential solutions.
  4. Subsequently, subgroup leads develop a document based on the meeting with sections for main topics and find leads for each of the sections. Completed by January 29.
  5. Leads for main topics draw on other subgroup members to complete an initial draft by �February 12.
  6. Entire subgroup edits, refines, expands document, including references etc. Final document delivered to working group leads by February 26.

Should be added to the subgroup’s Wiki page

IMAG/MSM Wiki Pages

The Viral Pandemics WG has an IMAG/MSM Wiki page at:�https://www.imagwiki.nibib.nih.gov/working-groups/multiscale-modeling-and-viral-pandemics

In addition, each subgroup can have their own WIki page.

IMAG/MSM Wiki Pages

We ask that:

  1. Each group identify someone to update their group’s Wiki page.
    1. If the group prefers, they can maintain a page outside the IMAG Wiki (for example, at SimTK or GitHub)
  2. To update your group’s Wiki;
    • Contact Jim Sluka (JSluka@iu.edu) and I will copy the subgroup template to a new page for your subgroup.
    • Register as a member of the IMAG/MSMS so you have edit-access to all the Wiki page. (Details are on the next page or contact jsluka@iu.edu.)
