Since the beginning of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, pharmaceutical companies and research institutions have been actively working to develop vaccines, and the mass roll-out of vaccinations against COVID-19 began in January 2021. At the same time, during lockdowns, the consumption of alcoholic beverages increased. During the peak of vaccination, consumption remained at high levels around the world, despite the gradual relaxation of quarantine restrictions. Two of the popular queries on search engines were whether it is safe to drink alcohol after vaccination and whether this will affect the effectiveness of vaccines. Over the past two …

Analysis Of Covid-19 In Rural America, Ian Gabriel Derickson

Graduate Student Theses, Dissertations, & Professional Papers

The outbreak of the novel coronavirus (SARS-CoV-2) in Wuhan, China and subsequent global pandemic illustrated the need of accurate forecasting and a greater understanding of the underlying dynamics of infectious diseases.

In this dissertation, we examine the six most populous towns in the State of Montana through the lens of the classic SIR model. With this, we show that the six towns in question exhibit similar disease dynamics and population behavior within each wave. Furthermore, we conduct analysis on the age demographics of COVID-19 cases and deaths. This analysis corroborates the findings of the SIR model fits, in that the …

Journal Articles: Epidemiology

BACKGROUND: Symptomatic patients who test negative for common viruses are an important possible source of unrecognised or emerging pathogens, but metagenomic sequencing of all samples is inefficient because of the low likelihood of finding a pathogen in any given sample. We aimed to determine whether nasopharyngeal CXCL10 screening could be used as a strategy to enrich for samples containing undiagnosed viruses.

METHODS: In this pathogen surveillance and detection study, we measured CXCL10 concentrations from nasopharyngeal swabs from patients in the Yale New Haven health-care system, which had been tested at the Yale New Haven Hospital Clinical Virology Laboratory (New Haven, …

The Shortfalls Of Vulnerability Indexes For Public Health Decision-Making In The Face Of Emergent Crises: The Case Of Covid-19 Vaccine Uptake In Virginia, Lydia Cleveland Sa, Erika Frydenlund

VMASC Publications

Equitable and effective vaccine uptake is a key issue in addressing COVID-19. To achieve this, we must comprehensively characterize the context-specific socio-behavioral and structural determinants of vaccine uptake. However, to quickly focus public health interventions, state agencies and planners often rely on already existing indexes of "vulnerability." Many such "vulnerability indexes" exist and become benchmarks for targeting interventions in wide ranging scenarios, but they vary considerably in the factors and themes that they cover. Some are even uncritical of the use of the word "vulnerable," which should take on different meanings in different contexts. The objective of this study is …

Inequitable By Design: The Patent Culture, Law, And Politics Behind Covid-19 Vaccine Global Access, Ximena Benavides

University of Michigan Journal of Law Reform

COVID-19 vaccine access has been highly inequitable worldwide, with coverage depending largely on a country’s wealth. By the end of 2021, 64.1% of people living in high-income countries had received at least one dose of the vaccine, compared to only 5.4% of those in low-income countries. Similarly, only high- and upper-middle-income countries had received the most effective vaccines.

The uneven distribution of these lifesaving vaccines is made complex due to the convergence of several factors, but it suggests that the extraordinary expanding and ossifying market and political power of a few vaccine manufacturers founded on intellectual property and complementary policies …

Molecular analysis of public wastewater has great potential as a harbinger for community health and health threats. Long-used to monitor the presence of enteric viruses, in particular polio, recent successes of wastewater as a reliable lead indicator for trends in SARS-CoV-2 levels and hospital admissions has generated optimism and emerging evidence that similar science can be applied to other pathogens of pandemic potential (PPPs), especially respiratory viruses and their variants of concern (VOC). However, there are substantial challenges associated with implementation of this ideal, namely that multiple and distinct fields of inquiry must be bridged and coordinated. These include engineering, …

Examining The Impact Of The Covid-19 Pandemic And Subsequent Vaccine Availability On Children’S Social Play Opportunities With A Focus On The Autism Community, Jenni Koehler

All ETDs from UAB

Play, especially social play, is crucial to child development and impacts their cognitive, socioemotional, and motor growth. Children with an autism spectrum disorder (ASD) have social and motor impairments that act as barriers to their access to these critical social play opportunities. Those who are able to overcome these barriers through therapy have been shown to have better physical and mental outcomes. Unfortunately, the COVID-19 pandemic restricted social play opportunities for all children and disproportionately impacted children with ASD, further widening developmental gaps between them and their non-autistic peers. The development of the COVID-19 vaccine and its availability to children …

Faculty, Staff and Student Publications

In late 2019, the emergence of COVID-19 in Wuhan, China, led to the implementation of stringent measures forming the zero-COVID policy aimed at eliminating transmission. Zero-COVID policy basically aimed at completely eliminating the transmission of COVID-19. However, the relaxation of this policy in late 2022 reportedly resulted in a rapid surge of COVID-19 cases. The aim of this work is to investigate the factors contributing to this outbreak using a new SEIR-type epidemic model with time-dependent level of immunity. Our model incorporates a time-dependent level of immunity considering vaccine doses administered and time-post-vaccination dependent vaccine efficacy. We find that vaccine …
