Mathematical modeling of SARS-CoV-2 life cycle and COVID-19 vaccine response
FY 2020-21 · 2021-03-01
Summary
This Project proposes a modeling platform to quickly explore vaccine designs using simulation and Machine Learning algorithms. A recently developed base model describes the life-cycle of the virus and includes a general immune response. Extension of the model to study pathogen mutation and ‘viral fitness’ is currently underway. The main focus of the proposed work will be the development of a complementary mathematical model that rigorously describes the host immune system to elucidate the complex interactions between interferon signaling pathways and the adaptive immune response to SARS-CoV-2 infection. Collectively these models will be crucial to defining vaccine strategies, and will provide a qualitative and quantitative platform to test and guide vaccine development.
Since December 2020, there has been a few new strains of the coronavirus. Namely the UK (SARS-CoV-2 VOC 202012/01) and South Africa strain (501Y.V2) are among the more prevalent. The UK strain has already spread to Canada. The current vaccine was not developed with these new strains in mind. For that matter, further mutation of the virus can be anticipated. The current distributed vaccine that was approved in the interim is a mRNA based vaccine. While this vaccine completed clinical trials overseas, it was not tested in Canada and Health Canada have an interim approval due to the emergency. There are many vaccine candidates using other technologies that are currently in development in Canada and overseas such as instance Providence Therapeutics, Medicago, and VBI. This Project proposes a modeling framework that can be applied to test new candidates and compare to those that have been approved/distributed in Canada.
There are significant values in testing vaccines against new strains of the virus and optimizing current vaccine design against new strains. The Project’s mathematical model can be quickly modified to rapidly address the new challenges SARS-CoV-2 variants pose.

Description (French)
Le projet propose une plateforme de modélisation avec laquelle on pourra explorer rapidement un vaccin quelconque par la simulation et au moyen d’algorithmes d’apprentissage automatique. Un modèle de base, élaboré depuis peu, décrit le cycle de vie du virus et la réaction générale qu’il engendre dans le système immunitaire. S’y ajoutera bientôt un module qui servira à étudier les mutations de l’agent pathogène et la « capacité d’adaptation » du virus. Les travaux porteront sur le développement d’un modèle mathématique complémentaire qui décrira rigoureusement le système immun de l’hôte afin d’élucider les interactions complexes entre les systèmes de signalisation des interférons et la modulation de la réaction immune à l’infection par le SRAS-CoV-2. De tels modèles sont indispensables pour échafauder des stratégies de vaccination et constitueront une plateforme à la fois qualitative et quantitative pour tester les vaccins et en orienter le développement.
Quelques nouvelles souches du coronavirus ont fait leur apparition depuis décembre 2020, les plus courantes étant les variants britannique (SRAS-CoV-2 VOC 202012/01) et sud-africain (501Y.V2). Le premier a déjà commencé à se propager au Canada. Or, le vaccin actuel n’a pas été créé en fonction des nouveaux variants. Par ailleurs, il faut s’attendre à ce que le virus subisse d’autres mutations. Le vaccin homologué pour l’instant et actuellement distribué est un vaccin reposant sur l’ARN messager. Bien qu’il ait fait l’objet d’essais cliniques complets à l’étranger, il n’a pas été testé au Canada et Santé Canada ne lui a accordé d’approbation provisoire que face à l’urgence de la situation. Maints vaccins qui reposent sur d’autres technologies sont en cours de développement au Canada et ailleurs, par exemple ceux de Providence Therapeutics, de Medicago et de VBI. Le projet propose un cadre de modélisation dont on se servira pour tester les futurs vaccins et les comparer à ceux qui ont été homologués et sont administrés au Canada.
Il est très utile de tester les vaccins contre les nouvelles souches du virus et d’optimiser la conception actuelle des vaccins contre les nouvelles souches. Le modèle mathématique du projet pourra être modifié rapidement en fonction des difficultés que soulèvent les nouvelles mutations du SRAS-CoV-2.
