The University of Louisville Journal of Respiratory Infections

Background: Response to the COVID-19 pandemic has required innovative approaches to vaccination, including methods to rapidly and safely immunize communities. A major challenge to such a response involved access to untapped healthcare worker resources. The Louisville, Kentucky, response involved the use of a large volunteer workforce to supplement local public health employees in planning and implementing a large-scale drive-through vaccination event. The objective of this manuscript was to outline processes involved in training a mass immunization workforce and implementating a large-scale COVID-19 community vaccination.

Approach: Competency-based and standardized training was provided for every volunteer before working their shift. Volunteers worked …

Pseudomonas Aeruginosa Vaccine Development Using Dual-Species Whole Cell And Subunit Vaccines, Catherine Bell Blackwood

Graduate Theses, Dissertations, and Problem Reports

Pseudomonas aeruginosa is a Gram-negative opportunistic pathogen which can cause severe, recurrent, and chronic infections. The pathogen is highly adaptable, and pneumonia caused by it is associated with high morbidity and mortality, especially in individuals with the genetic disorder cystic fibrosis. Antibiotic resistance amongst clinical isolates of P. aeruginosa is steadily increasing, and multi-drug resistant strains are prevalent. There is currently no vaccine available for commercial use against P. aeruginosa. For these reasons, we sought to understand the immunity to P. aeruginosa induced by whole cell vaccination and identify antigens for development of future subunit vaccines. In this dissertation, …

Why The Government Shouldn't Pay People To Get Vaccinated Against Covid-19, Ana Santos Rutschman

All Faculty Scholarship

As several pharmaceutical companies approach the Food and Drug Administration (FDA) seeking authorization to bring COVID-19 vaccines to market, concerns about vaccine mistrust cloud the prospects of imminent vaccination efforts across the globe. These concerns have prompted some commentators to suggest that governments may nudge vaccine uptake by paying people to get vaccinated against COVID-19. This post argues that, even if potentially viable, this idea is undesirable against the backdrop of a pandemic marked by the intertwined phenomena of health misinformation and mistrust in public health authorities. Even beyond the context of COVID-19, paying for vaccination is likely to remain …

Superantigen Responsive T Cells Are Required For Nasopharyngeal Infection By Streptococcus Pyogenes, Joseph J. Zeppa

Electronic Thesis and Dissertation Repository

Streptococcus pyogenes is a human-specific pathogen that is responsible for serious morbidity and mortality worldwide despite being susceptible to common antibiotics. Furthermore, there is currently no licensed vaccine available against this organism. Previous research from our laboratory implicated a critical role for SAgs in a transgenic mouse model of acute nasopharyngeal infection by S. pyogenes. Herein, we are able to detect SAg production in vivo and establish that anti-SAg antibodies generated by either passive immunization or active vaccination with a MHC II-binding interface SAg toxoid reduces S. pyogenes nasopharyngeal burden. We were also able to demonstrate that this organism …

Genetic And Genomic Basis Of Antibody Response To Porcine Reproductive And Respiratory Syndrome (Prrs) In Gilts And Sows, Nick V. Serão, Robert A. Kemp, Benny Mote, Philip Willson, John C.S. Harding, Stephen C. Bishop, Graham S. Plastow, Jack C.M. Dekkers

Department of Animal Science: Faculty Publications

Background: Our recent research showed that antibody response to porcine reproductive and respiratory syndrome (PRRS), measured as sample-to-positive (S/P) ratio, is highly heritable and has a high genetic correlation with reproductive performance during a PRRS outbreak. Two major quantitative trait loci (QTL) on Sus scrofa chromosome 7 (SSC7; QTL_MHC and QTL₁₃₀) accounted for ~40 % of the genetic variance for S/P. Objectives of this study were to estimate genetic parameters for PRRS S/P in gilts during acclimation, identify regions associated with S/P, and evaluate the accuracy of genomic prediction of S/P across populations with different prevalences of …

An Evolutionary Vaccination Game In The Modified Activity Driven Network By Considering The Closeness, Dun Han, Mei Sun

Publications and Research

In this paper, we explore an evolutionary vaccination game in the modified activity driven network by considering the closeness. We set a closeness parameter p which is used to describe the way of connection between two individuals. The simulation results show that the closeness p may have an active role in weakening both the spreading of epidemic and the vaccination. Besides, when vaccination is not allowed, the final recovered density increases with the value of the ratio of the infection rate to the recovery rate λ/μ. However, when vaccination is allowed the final density of recovered individual first increases and …

Analysis Of The Morbidity And Mortality Of Severe Influenza Infection In Clark County, Nevada For The 2010-2011 Influenza Season, Kindra St. Jacques, Patricia Cruz, Brian Labus

Nevada Journal of Public Health

Throughout the duration of any influenza season, influenza strains have the ability to evolve through mutation causing alterations in virulence. These changes may result in severe illness or death among susceptible populations; therefore, it is important to closely monitor influenza-associated hospitalizations and deaths. The University of Nevada, Las Vegas in collaboration with the Southern Nevada Health District analyzed data from the hospitalized influenza morbidity and mortality surveillance project for Clark County for the 2010-2011 influenza season. Among the study population (N= 158): the influenza strain type was found to be significantly associated with deaths (n= 25), vaccination status was not …
