Optimized numerical solutions of SIRDVW multiage model controlling SARS-CoV-2 vaccine roll out: An application to the Italian scenario

Alfio Quarteroni, Luca Dede', Nicola Parolini

In the context of SARS-CoV-2 pandemic, mathematical modelling has played a funda-mental role for making forecasts, simulating scenarios and evaluating the impact of pre-ventive political, social and pharmaceutical measures. Optimal control theory represent ...

Optimal control of the spatial allocation of COVID-19 vaccines: Italy as a case study

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Damiano Pasetto, Joseph Chadi Benoit Lemaitre

While campaigns of vaccination against SARS-CoV-2 are underway across the world, communities face the challenge of a fair and effective distribution of a limited supply of doses. Current vaccine allocation strategies are based on criteria such as age or ri ...

Projected resurgence of COVID-19 in the United States in July-December 2021 resulting from the increased transmissibility of the Delta variant and faltering vaccination

Francisco Javier Perez Saez

In Spring 2021, the highly transmissible SARS-CoV-2 Delta variant began to cause increases in cases, hospitalizations, and deaths in parts of the United States. At the time, with slowed vaccination uptake, this novel variant was expected to increase the ri ...

Preliminary evidence that daily light exposure enhances the antibody response to influenza vaccination in patients with dementia

Jean-Louis Scartezzini

Enhancing lighting conditions in institutions for individuals with dementia improves their sleep, circadian rhythms and well-being. Here, we report first findings that exposure to brighter light during daytime may support the immune response to the annual ...

Humoral Responses Against Variants of Concern by COVID-19 mRNA Vaccines in Immunocompromised Patients

Didier Trono

IMPORTANCE There are limited comparative data on the durability of neutralizing antibody (nAb) responses elicited by messenger RNA (mRNA) vaccines against the SARS-CoV-2 variants of concern (VOCs) in immunocompromised patients and healthy controls. ...

Identification of Vaccine Effects When Exposure Status Is Unknown

Mats Julius Stensrud

Results from randomized controlled trials (RCTs) help determine vaccination strategies and related public health policies. However, defining and identifying estimands that can guide policies in infectious disease settings is difficult, even in an RCT. The ...

Novel broad-spectrum virucidal antivirals

Matteo Gasbarri

The current COVID-19 pandemic has showed the threats that viruses can cause to the whole world. Over 200 million infections and over 4.5 million deaths and enormous socio-economic impact were the output of the emergence of a single new pathogen: SARS-CoV-2 ...

Modeling infectious disease dynamics towards informed public health interventions, with applications on COVID-19 and cholera

Joseph Chadi Benoit Lemaitre

Emerging and existing infectious diseases pose a constant threat to individuals and communities across the world. In many cases, the burden of these diseases is preventable through public health interventions. However, taking the right decisions and design ...

Adjuvant-free immunization with infective filarial larvae as lymphatic homing antigen carriers

Melody Swartz, Alexandre de Titta, Esra Güç, David Scott Wilson, Marcela Rincón-Restrepo, Sachiko Hirosue

Controlled infection with intestinal nematodes has therapeutic potential for preventing the symptoms of allergic and autoimmune diseases. Here, we engineered larvae of the filarial nematode Litomosoides sigmodontis as a vaccine strategy to induce adaptive ...

Contact networks across ages: computational analysis of epidemiological dynamics

Gianrocco Lazzari

For decades mathematical modeling in epidemiology has helped understanding the dynamics of infectious diseases, as well as describe possible intervention scenarios to prevent and control them. However, such models were relying on several assumptions, such ...

Inborn errors of type I IFN immunity in patients with life-threatening COVID-19

Jacques Fellay

Clinical outcome upon infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) ranges from silent infection to lethal coronavirus disease 2019 (COVID-19). We have found an enrichment in rare variants predicted to be loss-of-function (LOF ...

Assessing the Dynamics and Control of Droplet- and Aerosol-Transmitted Influenza Using an Indoor Positioning System

Marcel Salathé, Gianrocco Lazzari

There is increasing evidence that aerosol transmission is a major contributor to the spread of influenza. Despite this, virtually all studies assessing the dynamics and control of influenza assume that it is transmitted solely through direct contact and la ...

Interplay between cost and benefits triggers nontrivial vaccination uptake

Paolo De Los Rios, Alessio Vincenzo Cardillo

The containment of epidemic spreading is a major challenge in science. Vaccination, whenever available, is the best way to prevent the spreading, because it eventually immunizes individuals. However, vaccines are not perfect, and total immunization is not ...

Critical dynamics in population vaccinating behavior

Marcel Salathé, Sharada Prasanna Mohanty

Vaccine refusal can lead to renewed outbreaks of previously eliminated diseases and even delay global eradication. Vaccinating decisions exemplify a complex, coupled system where vaccinating behavior and disease dynamics influence one another. Such systems ...

Toll-like receptor 8 agonist nanoparticles mimic immunomodulating effects of the live BCG vaccine and enhance neonatal innate and adaptive immune responses

Jeffrey Alan Hubbell, Melody Swartz, Sachiko Hirosue, Alexandre de Titta

Background: Newborns display distinct immune responses, leaving them vulnerable to infections and impairing immunization. Targeting newborn dendritic cells (DCs), which integrate vaccine signals into adaptive immune responses, might enable development of a ...

Spatially explicit modeling of cholera epidemics

Flavio Finger

Understanding the epidemiology of cholera, when and where it occurs and how it spreads, is key to its prevention and control. Models can help to apprehend cholera outbreaks by providing insight into critical epidemiological processes, and may be used to ev ...

The 2014–2015 Ebola outbreak in West Africa: Hands On

Derek Pierre Christie

This article describes discussions held at the ICPIC 2015 conference in Geneva, where a one-day session focused on the 2014–2015 Ebola virus disease (EVD) outbreak in West Africa. Topics include the timeline of the international response, linkages between ...

Additives for vaccine storage to improve thermal stability of adenoviruses from hours to months

Francesco Stellacci, Paulo Henrique Jacob Silva, Randy Patrick Carney, Valeria Cagno

Up to 80% of the cost of vaccination programmes is due to the cold chain problem (that is, keeping vaccines cold). Inexpensive, biocompatible additives to slow down the degradation of virus particles would address the problem. Here we propose and character ...
