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 …

Cost-Effectiveness Analysis Of Targeted Herpes Zoster Vaccination In Adults 50-59 At Increased Cardiovascular Risk, Kathleen M. Glassner

USF Tampa Graduate Theses and Dissertations

Background: Over the last twenty years the incidence of herpes zoster (HZ) infection, also known as shingles, has been increasing among adults for unknown reasons. The economic burden of HZ is currently estimated at over $1 billion per year in the United States (U.S.) and is expected to increase as the susceptible adult population ages. HZ is caused by a re-activation of the varicella zoster virus (VZV), chicken pox, and more than 95% of adults living today carry the virus with a lifetime risk of 1 in 3 for developing HZ. In 2006 the FDA approved a vaccine for the …

Enhancing The Immune Response Through Ikkbeta-Induced Activation Of Nf-Kappab, Emily Hopewell

USF Tampa Graduate Theses and Dissertations

Nuclear factor-κB (NF-κB) is one of the main regulators of inflammatory and immune responses. It is a family of transcription factors composed of five members: RelA, RelB, cRel, NF-κB1 (p105/p50), and NF-κB2 (p100/p52). Homo- and hetero-dimers of family members are inhibited by inhibitor of &klappaB (IκB) family members and activated by IκB kinase (IKK) family members. The IKK family is comprised of IKKα, IKKΒ, and IKKγ. The focus of my dissertation delves into the role of NF-κB activation by IKKΒ in both an immunotherapy setting and its role in T cell mediated anti-tumor immune responses.

A central focus of immunotherapy …

Therapeutic Peptide-Based Vaccination Strategies Against Hpv-Induced Cancers, Kelly Barrios Marrugo

USF Tampa Graduate Theses and Dissertations

There is an urgent need for the development of an effective therapeutic vaccine against cancer caused by human papilloma virus (HPV). We focused on HPV-induced malignancies because of their high worldwide prevalence (e.g., cervical carcinoma and head & neck cancer). A successful therapeutic vaccine could prevent the 250 000 deaths/year worldwide and the 2.25 billion dollars that

are expended in related care in the US.

We used an HPV-induced mouse cancer model to test vaccines

composed of a CD8 T cell peptide epitope administered with potent adjuvants designed to generate vast numbers of high avidity cytotoxic T lymphocytes specific for …
