An Approach To Increase Education In The Flu Vaccination Clinic Process, Koki Guangxi Inlow, Lucy Dale, Devante Lindsey, Nancy Tran Manalo, Elena Teresa Cleary

Master's Projects and Capstones

The Health Ministries Program, located in Orange County, is supported by a large faith-based community hospital and provides community resources such as flu vaccinations that are overseen by the Faith Community Nurse (FCN). In collaboration with the program, University of San Francisco (USF) nursing students researched and developed an implementation of a multi-purpose educational flyer to increase education and better streamline the process at flu vaccination clinics throughout Orange County faith-based organizations. Research shows that many individuals still do not get vaccinated due to misconceptions, misinformation, and lack of knowledge on the importance of flu vaccinations. The cost of flu-related …

Incorporating B Cell Activating Factor (Baff) Into The Membrane Of Rabies Virus (Rabv) Particles Improves The Speed And Magnitude Of Vaccine-Induced Antibody Responses., Joseph R Plummer, James P Mcgettigan

Department of Microbiology and Immunology Faculty Papers

B cell activating factor (BAFF) is a member of the tumor necrosis factor (TNF) superfamily of cytokines that links innate with adaptive immunity. BAFF signals through receptors on B cells, making it an attractive molecule to potentiate vaccine-induced B cell responses. We hypothesized that a rabies virus (RABV)-based vaccine displaying both antigen and BAFF on the surface of the same virus particle would target antigen-specific B cells for activation and improve RABV-specific antibody responses. To test this hypothesis, we constructed a recombinant RABV-based vector expressing virus membrane-anchored murine BAFF (RABV-ED51-mBAFF). BAFF was incorporated into the RABV particle and determined to …

Smith, Tiago Abreu-Mota, Yong Yang, Felix R. Jackson, Nadia Gallardo-Romero, Richard Franka, Victor Bronshtein, Matthias J. Schnell

Department of Microbiology and Immunology Faculty Papers

BACKGROUND: Ebola virus (EBOV) is a highly lethal member of the Filoviridae family associated with human hemorrhagic disease. Despite being a sporadic disease, it caused a large outbreak in 2014-2016 in West Africa and another outbreak recently in the Democratic Republic of Congo. Several vaccine candidates are currently in preclinical and clinical studies but none are stable without cold chain storage.

METHODS: We used preservation by vaporization (PBV), a novel processing technology to heat-stabilize FiloRab1 (inactivated rabies-based Ebola vaccine), a candidate Ebola vaccine, and stored the vials at temperatures ranging from 4°C to 50°C for 10 days to 12 months. …

A Vaccine Administration Training Program To Increase Adolescent Vaccination Rates, Claire Jensen

Dissertations

Abstract

Immunizations have been proven to control life-threatening diseases. Often Registered Nurses (RNs) administer vaccines but are unsure how to discuss vaccines with vaccine hesitant patients. Missouri’s adolescent vaccination rates are below its neighboring states. This initiative’s purpose was to increase adolescent vaccine administrations at a Missouri County Health Department (MCHD).

This quality improvement initiative had an observational, cross-sectional, descriptive design. RNs employed at three MCHD clinics attended an adolescent vaccine administration training program (VAT) and completed pre-/post-tests regarding the Advisory Council on Immunization Practices recommendations. Medical record reviews from March 1-April 30, 2018 and March 1-April 30, 2019 compared …

Evolutionary Dynamics Of Influenza Type B In The Presence Of Vaccination: An Ecological Study, Lindsey J. Fiedler

USF Tampa Graduate Theses and Dissertations

Understanding the evolutionary dynamics of influenza type B in human hosts is a public health concern as we strive to minimize the disease burden in seasonal epidemics. Vaccination is considered the best defense against contracting influenza, and everyone over the age of 6 months is advised to get vaccinated before each season. The effect that vaccine-acquired immunity has on the evolution of influenza B remains unclear. In the U.S., vaccine-uptake is irregular across the states, and the differing coverages present an opportunity to study how vaccination influences viral evolution. This thesis analyzes the evolutionary patterns of influenza B in the …

How Health Care Providers Can Use Digital Health Technologies To Inform Human Papillomavirus (Hpv) Decision Making And Promote The Hpv Vaccine Uptake Among Adolescents And Young Adults, Versie Johnson-Mallard, Gabrielle Darville, Rebeccah Mercado, Charkarra Anderson-Lewis, Jann Macinnes

Faculty Publications

High-risk stains of human papillomavirus (HPV) is linked to causing cancer, is highly prevalent, and has increased incidence among adolescents and young adults. However, vaccination rates are low. Health care provider recommendation is the biggest influencer toward vaccine uptake. Since more health care providers are using digital health technologies in their medical practices, this study investigated the feasibility of technology to increase informed decision making. A convenience sample of 210 students completed an online survey. Participants were 18–25 years of age (88%), female (85%), Caucasian (60%), and never been diagnosed with HPV (92.9%). Overwhelmingly, participants owned a smartphone (98.9%) and …

Preparation And Evaluation Of Single-Stranded Dna Aptamer-Based Immunological Adjuvant In Broiler Chickens, Adil Sabr Al-Ogaili

Graduate Theses and Dissertations

Mineral oils and metal salts are commonly used as adjuvants to enhance acquired immunity. Recently, monoclonal antibodies (MAbs) and recombinant peptides agonist CD40 receptor have shown remarkable promise for induction of rapid and robust immune responses. Limitations of this approach MAb production costs and multiple administrations due to anti-MAb immune responses. Here we demonstrate the development of a unique and sophisticated DNA aptamer-based alternative for CD40-directed delivery of universal antigens as an alternative in chickens, and potentially other vertebrate species. This receptor, expressed by antigen-presenting cells, acts as a costimulatory molecule for activated T helper lymphocytes. After initially selecting for …

Department of Pharmacology and Experimental Therapeutics Faculty Papers

Background: The colorectal cancer antigen GUCY2C exhibits unique split tolerance, evoking antigen-specific CD8+, but not CD4+, T-cell responses that deliver anti-tumor immunity without autoimmunity in mice. Here, the cancer vaccine Ad5-GUCY2C-PADRE was evaluated in a first-in-man phase I clinical study of patients with early-stage colorectal cancer to assess its safety and immunological efficacy.

Methods: Ten patients with surgically-resected stage I or stage II (pN0) colon cancer received a single intramuscular injection of 1011 viral particles (vp) of Ad5-GUCY2C-PADRE. Safety assessment and immunomonitoring were carried out for 6 months following immunization. This trial employed continual monitoring of both efficacy and toxicity …

Implementation Of The Vaccines For Children Program In A Midwest, Urban Clinic Dedicated To The Underserved Population, Akmal Saydazamov

Doctoral Projects

Background: Low immunization rates weaken herd immunity and endanger children. The Safety Net Health Clinic (SNHC) study site serves an underprivileged and refugee population with significantly lower than ideal coverage. Series completion disparities persisted after control for demographic, access-to-care, poverty and language effects (Varan et al, 2016).

Objectives: SNHC implemented the Vaccines for Children (VFC) program in order to increase the vaccination rates among the underserved population.

Methods: As an efficacy study, the project focused on three major areas in the VFC implementation – cost, staff preparedness and patient need. Cost was determined by utilizing electronic medical records (EMR) and …

The Deadly Influenza Virus And Its Changing Forms, Kayce Boggess

D.U.Quark

The influenza virus has plagued humans for centuries. Recently antiviral medications, which shorten the duration of the flu, have been introduced into society. These medications along with vaccinations, which try to give the body immunity before the virus strikes, help to stop the flu before it attacks the host. The virus, however, replicates using host cells and can slightly change itself with each replication, which over time could lead to a strain immune to the current antiviral medication and vaccines. However, using more preventative measures could help slow the changing strains of the flu virus. Using vaccines to stop the …

A Qualitative Examination Of Vaccine Hesitancy Among Mothers, Alicia L. Benner, Annie Vasterling, Teia Wolter

All Electronic Theses and Dissertations

Vaccine hesitancy describes the reluctance to vaccinate or the delay of vaccines (World Health Organization [WHO], 2017a). Various factors contribute to vaccine hesitancy for patients (Salmon, Dudley, Glanz, & Somer, 2015), and multiple sources are used by patients to gain vaccine information (Salmon et al., 2015), making it difficult for healthcare providers to address vaccine hesitancy. This research was conducted to identify factors that cause mothers to be vaccine hesitant and information sources used to support the mothers’ vaccination beliefs. Phone interviews were conducted with twelve vaccine hesitant mothers. Participants were asked if the following factors contributed to their vaccine …

Pseudomonas aeruginosa is an opportunistic pathogen causing acute and chronic respiratory infections associated with morbidity and mortality, especially in patients with cystic fibrosis. Vaccination against P. aeruginosa before colonization may be a solution against these infections and improve the quality of life of at-risk patients. To develop a vaccine against P. aeruginosa, we formulated a novel peptide-based P. aeruginosa subunit vaccine based on the extracellular regions of one of its major siderophore receptors, FpvA. We evaluated the effectiveness and immunogenicity of the FpvA peptides conjugated to keyhole limpet hemocyanin (KLH) with the adjuvant curdlan in a murine vaccination and challenge …

Performance Differences Between Two Groups Of Commercial Pigs Following Experimental Infection With Prrs Virus 1-7-4, Erin Little

Electronic Theses and Dissertations

Porcine reproductive and respiratory syndrome virus (PRRSV) is the costliest swine disease in North America. Vaccines and management alone have not been effective in controlling this disease. Genetic selection for resilience may be a complimentary approach for controlling PRRSV. The objective of this study was to estimate performance differences between two groups of pigs from the same commercial line following infection with PRRSV 1-7-4: 1) pigs sired by boars selected based on a standard index (TN-S), which emphasized feed efficiency and carcass quality; and 2) pigs sired by boars selected based on an experimental index (TN-E), which emphasized feed intake, …

Zika And Flavivirus Shell Disorder: Virulence And Fetal Morbidity, Gerard Kian-Meng Goh, A. Keith Dunker, James A. Foster, Vladimir N. Uversky

Molecular Medicine Faculty Publications

Zika virus (ZIKV) was first discovered in 1947 in Africa. Since then, sporadic ZIKV infections of humans have been reported in Africa and Asia. For a long time, this virus was mostly unnoticed due to its mild symptoms and low fatality rates. However, during the 2015–2016 epidemic in Central and South America, when millions of people were infected, it was discovered that ZIKV causes microcephaly in the babies of mothers infected during pregnancy. An examination of the M and C proteins of the ZIKV shell using the disorder predictor PONDR VLXT revealed that the M protein contains relatively high disorder …

A Single-Cycle Adenovirus Type 7 Vaccine For Prevention Of Acute Respiratory Disease, Brianna L. Bullard, Brigette N. Corder, Eric A. Weaver

Nebraska Center for Virology: Faculty Publications

Adenovirus type 7 (Ad7) infection is associated with acute respiratory disease (ARD), especially in military recruits living in close quarters. Recently, several outbreaks of Ad7 infections have occurred in civilian populations, with some cases leading to death. However, the current Ad7 vaccine is licensed for use only in military recruits because it utilizes an orally delivered wild type virus which is shed in the stool for 28 days after immunization. This poses a safety risk due to the possibility of virus spread to vulnerable populations. To address the need for a safer Ad7 vaccine for use in civilian populations, we …

The Role Of Cd8 T Cell Immunodominance And Regulatory T Cells In Neonatal Immunity To Influenza Virus, Luke Heil

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

Neonates are more susceptible to influenza virus infection than adults, resulting in increased morbidity and mortality as well as delayed clearance of the virus. Efforts to improve influenza infection outcomes in neonates typically center on prevention, although current vaccines fall short of complete protection and can only be administered in humans after 6 months of life. We propose that as the neonatal immune system responds differently than the adult immune system, interventions that are efficacious or tolerable in adults cannot be guaranteed to perform the same in neonates. T cell vaccines that target conserved influenza virus epitopes have been proposed …

This project aims to highlight various medical providers' opinions on the barriers to HPV vaccination for young men in Newtown, Connecticut, as well as, address methods for improvement including …

Trypanosoma Cruzi Trypomastigote Glycosylphosphatidylinositol-Anchored Mucins And A Synthetic Alpha-Gal-Containing Neoglycoprotein As Potential Biomarkers And Vaccines For Chagas Disease, Igor Leandro Estevao

Open Access Theses & Dissertations

Chagas disease (CD), caused by the protozoan Trypanosoma cruzi, is a neglected tropical disease that kills or permanently disable thousands of people annually. About 6-8 million people are estimated to be infected worldwide. Although many efforts have been made for the development of an effective immunotherapy, currently there is no vaccine to prevent or treat CD in humans. Despite their toxicity, the two current drugs for CD, benznidazole (BZN) and nifurtimox (NFX), have medium-to-high efficacy in the chronic stage of the disease and could save or improve the lives of thousands of patients. However, negative seroconversion in treated patients, as …

Efficacy Of A Single Dose Hpv Vaccine And Its Potential Outcomes In Low-Income Countries, Brooke Schramm

Theses and Graduate Projects

Cervical cancer is a leading worldwide cause of cancer mortality in women and disproportionately burdens low-income countries. Human papillomavirus (HPV) has been proven as the primary cause of genital warts, some oropharyngeal cancers, and anogenital cancers such as cervical, vulvar, anal, and penile malignancies. HPV vaccination coupled with regular HPV screenings are major strategies for preventing HPV infections, but with high costs and infrastructure complexities associated with current vaccination and screening programs, many world regions are unable to provide protection against HPV infection and its sequalae. If unabated, cervical cancer incidence is expected to increase worldwide over the coming decades …

Nanosecond Pulsed Electric Fields Induce Endoplasmic Reticulum Stress Accompanied By Immunogenic Cell Death In Murine Models Of Lymphoma And Colorectal Cancer, Alessandra Rossi, Olga N. Pakhomova, Peter A. Mollica, Maura Casciola, Uma Mangalanathan, Andrei G. Pakhomov, Claudia Muratori

Bioelectrics Publications

Depending on the initiating stimulus, cancer cell death can be immunogenic or non-immunogenic. Inducers of immunogenic cell death (ICD) rely on endoplasmic reticulum (ER) stress for the trafficking of danger signals such as calreticulin (CRT) and ATP. We found that nanosecond pulsed electric fields (nsPEF), an emerging new modality for tumor ablation, cause the activation of the ER-resident stress sensor PERK in both CT-26 colon carcinoma and EL-4 lymphoma cells. PERK activation correlates with sustained CRT exposure on the cell plasma membrane and apoptosis induction in both nsPEF-treated cell lines. Our results show that, in CT-26 cells, the activity of …
