School of Public Health Faculty Publications

Previous research demonstrated Non-Hispanic Black populations experience higher COVID-19 mortality rates than Non-Hispanic White individuals. Additionally, cancer status is a known risk factor for COVID-19 death. While prior studies investigated comorbidities as exploratory variables in differences in COVID-19 hospitalization, none have explored their role in COVID-19-related deaths. This study aimed to evaluate whether Charlson Comorbidity Index (CCI) and subsequently, individual diseases are potential explanatory variables for this relationship. The analysis focused on Non-Hispanic Black and Non-Hispanic White cancer patients aged 20 or older, diagnosed between 2011 and 2019, who tested positive for COVID-19 from the start of pandemic through June …

BACKGROUND: Scalable identification of patients with post-acute sequelae of COVID-19 (PASC) is challenging due to a lack of reproducible precision phenotyping algorithms, which has led to suboptimal accuracy, demographic biases, and underestimation of the PASC.

METHODS: In a retrospective case-control study, we developed a precision phenotyping algorithm for identifying cohorts of patients with PASC. We used longitudinal electronic health records data from over 295,000 patients from 14 hospitals and 20 community health centers in Massachusetts. The algorithm employs an attention mechanism to simultaneously exclude sequelae that prior conditions can explain and include infection-associated chronic conditions. We performed independent chart reviews …

Overcoming Vaccine Hesitancy: Evidence From Italy During The Covid-19 Pandemic, Alessandro Del Ponte, Audrey De Dominicis, Paolo Canofari

Political Science Faculty Articles and Research

Objectives

Here we investigate whether releasing COVID-19 vaccines at open-day events boosted Italy's vaccination campaign in 2021. This strategy exploits insights from psychology.

Study design

We built an original dataset covering 200 days of vaccination data in Italy, including “open day” events. Open-day events (in short: open days) are instances where COVID-19 vaccines were released only for a specific day at a specified location (usually, a large pavilion or a public building). Importantly, releasing vaccines through open days instead of the usual appointment channel leaves the supply of vaccines unaltered. Our dependent variables are the number of total and first …

False Narratives, Real Consequences, Russell W. Cantrell, Matt Campbell

Shelby Hall Graduate Research Forum Posters

Social media is an increasingly significant tool in modern cyber warfare, capable of rapidly shaping public opinion. The swift dissemination of information complicates efforts to distinguish fact from fiction [1]. During public health crises, healthcare professionals use these platforms to share updates, yet their credible content must contend with false or deliberately misleading narratives [2]. This environment creates an opportunity for cyberattacks through social media influence campaigns [3]. While disinformation's role in political interference has been widely studied, its potential to destabilize healthcare remains largely unexplored. Prior research primarily focuses on how vaccine misinformation affects the general public [4]. This …


The Importance Of Public Health In College Populations: Why Vaccines Are Important, Kashish Poore Mar 2025

The Importance Of Public Health In College Populations: Why Vaccines Are Important, Kashish Poore

Honors Program: Senior Projects (Public)

This paper examines the importance of vaccines in college populations, where high-density living environments create unique vulnerabilities to infectious disease outbreaks. Despite vaccine mandates at most institutions, research indicates that many college students possess incomplete understanding of vaccine mechanisms and importance. The paper addresses three interconnected aspects: the biological foundations of vaccine-induced immunity, the significance of vaccination in collegiate settings, and the current state of vaccine literacy among students. Historical outbreaks on campuses, including meningitis at Princeton and mumps across several institutions, highlight the consequences of undervaccination. Social media misinformation has contributed significantly to vaccine hesitancy, particularly since COVID-19. The …

Faculty, Staff and Student Publications

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-induced coronavirus disease 2019 (COVID-19) pandemic has challenged the current understanding of the complement cascade mechanisms of host immune responses during infection-induced nonresolvable lung disease. While the complement system is involved in opsonization and phagocytosis of the invading pathogens, uncontrolled complement activation also leads to aberrant autophagic response and tissue damage. Our recent study revealed unique pathologic and fibrotic signature genes associated with epithelial bronchiolization in the lung tissues of patients with nonresolvable COVID-19 (NR-COVID-19) requiring lung transplantation. However, there is a knowledge gap if complement components are modulated to contribute to tissue …

Relationship Between Prevalence Of Disability And Receiving The Covid-19 Vaccine Abstract, Brady Beard, Michael Treichler, Kevin Gittner

Symposium of Student Scholars

COVID-19 vaccines were developed to reduce the spread and severity of the virus, particularly among vulnerable populations. People with disabilities are at higher risk of severe outcomes from COVID-19 due to underlying health conditions, limited access to healthcare, and potential barriers to preventive measures like social distancing. Despite their vulnerability, disabled individuals may face challenges in accessing vaccines, such as physical barriers, transportation issues, or a lack of tailored information. Additionally, vaccine hesitancy may be influenced by concerns about potential side effects harming existing disabilities. This study investigates the research question: "Is there a relationship between receiving the COVID-19 vaccine …

Verkhivker

Mathematics, Physics, and Computer Science Faculty Articles and Research

A growing body of experimental and computational studies suggests that the cross-neutralization antibody activity against Omicron variants may be driven by the balance and tradeoff between multiple energetic factors and interaction contributions of the evolving escape hotspots involved in antigenic drift and convergent evolution. However, the dynamic and energetic details quantifying the balance and contribution of these factors, particularly the balancing nature of specific interactions formed by antibodies with epitope residues, remain largely uncharacterized. In this study, we performed molecular dynamics simulations, an ensemble-based deep mutational scanning of SARS-CoV-2 spike residues, and binding free energy computations for two distinct groups …

One Center's Experience Of Pulmonary Embolism After Covid-19: Impact Of Vaccination Status, Cara Gose, Kaylee Dixon, Andrea M. Bodine Md

Advances in Clinical Medical Research and Healthcare Delivery

Background: The incidence of pulmonary embolism (PE) has increased since the outbreak of the COVID-19 pandemic and may be due to the observed hypercoagulable state. There is conflicting evidence that thromboembolism risk increases after vaccination and that vaccines decrease the probability of having a thromboembolic event. This study aimed to explore how vaccination status impacts occurrence of PE after a positive COVID-19 test. The hypothesis was that vaccinated, immunocompetent patients have a lower incidence of PE after COVID-19 compared to unvaccinated patients.

Methods: This was a retrospective chart review at a teaching hospital in New England from 1/01/2021 to 3/31/2023 …

Background: Lymphopenia and failure of lymphocytes to mount an early IFN-γ response correlate with increased mortality in COVID-19. Given the essential role of CD4 helper and CD8 cytotoxic cells in eliminating viral pathogens, this profound loss in lymphocytes may impair patients' ability to eliminate the virus. IL-7 is a pleiotropic cytokine that is obligatory for lymphocyte survival and optimal function.

Methods: We conducted a prospective, double-blind, randomized, placebo-controlled trial of CYT107, recombinant human IL-7, in 109 critically ill, patients with lymphopenia who have COVID-19. The primary endpoint was to assess CYT107's effect on lymphocyte recovery with secondary clinical endpoints including …
