Rapid development of vaccines for COVID-19 has relied on the application of existing vaccine technologies. This work examines the maturity of ten technologies employed in candidate vaccines (as of July 2020) and NIH funding for published research on these technologies from 2000–2019. These technologies vary from established platforms, which have been used successfully in approved products, to emerging technologies with no prior clinical validation. A robust body of published research on vaccine technologies was supported by 16,358 fiscal years of NIH funding totaling $17.2 billion from 2000–2019. During this period, NIH funding for published vaccine research against specific pandemic threats …

My Body, My Temple: The Constitutional Requirement For Religious Exemptions To A Covid-19 Vaccination Mandate, Ben Davisson
SLU Law Journal Online
While the COVID-19 crisis has caused many to fear the threat that the virus poses to the health and safety of themselves and their loved ones, for others, and particularly for those with certain religious beliefs, the cure is worse than the disease. The possibility of a government mandated vaccine has caused extreme anxiety for many Americans. In this article, Ben Davisson discusses the constitutionality of mandatory vaccination programs and how such programs may come into conflict with the Free Exercise Clause of the First Amendment.

Immunization with an insect cell lysate/baculovirus mixture containing recombinant porcine epidemic diarrhea virus (PEDV) spike protein induced high levels of neutralizing antibodies in both mice and piglets. However, immunization of piglets with this vaccine resulted in enhancement of disease symptoms and virus replication in vaccine recipients exposed to PEDV challenge. Thus, these observations demonstrate a previously unrecognized challenge of PEDV vaccine research, which has important implications for coronavirus vaccine development.

Recognizing the need for flexibility in times of emergency and building upon knowledge gained from existing international and domestic compulsory licensing laws, we propose a global, centralized scheme to provide access to vaccines during pandemics. In many ways our proposal mirrors some of the World Health Organization's (WHO) COVID-19 vaccine initiatives but consolidates and expands them into a much more efficacious form. Under the proposed model, the WHO's declaration of a pandemic would trigger a global procurement and distribution scheme for vaccines. The proposed scheme would be mandatory and would require that all countries operate as one buyer vis-a-vis vaccine …

John Steinbeck drew the title of his novel “Of Mice and Men” from a line in a Robert Burns poem “To a mouse”: “The best-laid plans of mice and men/Go often awry.” Unlike John Steinbeck who used the title to mirror the characters who were struggling during the Great Depression to the mouse whose nest was accidentally destroyed by the poet (Burns 1785), we chose this line to emphasize that the best-laid plan can go wrong in infectious disease control and prevention. Here, we will discuss the contributing factors behind the global successes and failures in the prevention and control …

The understanding of the public response to COVID-19 vaccines is the key success factor to control the COVID-19 pandemic. To understand the public response, there is a need to explore public opinion. Traditional surveys are expensive and time-consuming, address limited health topics, and obtain small-scale data. Twitter can provide a great opportunity to understand public opinion regarding COVID-19 vaccines. The current study proposes an approach using computational and human coding methods to collect and analyze a large number of tweets to provide a wider perspective on the COVID-19 vaccine. This study identifies the sentiment of tweets using a machine learning …

We find ourselves at a momentous turn in the history of vaccines. The COVID-19 pandemic triggered a quasi-global vaccine race that not only compressed vaccine research and development (R&D) timelines, but also paved the way for the administration of a new type of vaccine technology – mRNA vaccines, which work in substantially different ways from the vaccines in use before the pandemic.
While the process of bringing emerging COVID-19 vaccines to market has taken place in an unusually short timeframe, it was largely predicated on the same scientific and regulatory processes that govern the development, approval and deployment of new …

BACKGROUND: Adenovirus serotype 5 (Ad5) is a commonly used viral vector for transient delivery of transgenes, primarily for vaccination against pathogen and tumor antigens. However, endemic infections with Ad5 produce virus-specific neutralizing antibodies (NAbs) that limit transgene delivery and constrain target-directed immunity following exposure to Ad5-based vaccines. Indeed, clinical trials have revealed the limitations that virus-specific NAbs impose on the efficacy of Ad5-based vaccines. In that context, the emerging focus on immunological approaches targeting cancer self-antigens or neoepitopes underscores the unmet therapeutic need for more efficacious vaccine vectors.
METHODS: Here, we evaluated the ability of a chimeric adenoviral vector (Ad5.F35) …
Developing A Virus-Like Particle (Vlp)-Based Vaccine For Neisseria Gonorrhoeae, Ashvini Vaidya
Developing A Virus-Like Particle (Vlp)-Based Vaccine For Neisseria Gonorrhoeae, Ashvini Vaidya
Biomedical Sciences ETDs
Neisseria gonorrhoeae (Ng) is a sexually transmitted bacterium that infects human reproductive mucosal surfaces. Due to the risk of complications in untreated cases and evolving antibiotic resistance, a prophylactic vaccine is critical for preventing infection. There are four Ng outer-membrane proteins that contribute to Ng survival and resistance: PorB, BamA, TbpA, and MtrE. Each protein contains surface-exposed loops that are targets of bactericidal antibodies. Vaccines were developed by displaying Ng epitopes on the surface of bacteriophage virus-like particles (VLP). VLPs are immunogenic, multivalent, self-assembling complexes composed of viral structural proteins. Antigenic peptide sequences can be displayed on the surface …

Department of Biochemistry and Molecular Biology Faculty Papers
Rabies is nearly 100% lethal in the absence of treatment, killing an estimated 59,000 people annually. Vaccines and biologics are highly efficacious when administered properly. Sixteen rabies-related viruses (lyssaviruses) are similarly lethal, but some are divergent enough to evade protection from current vaccines and biologics, which are based only on the classical rabies virus (RABV). Here we present the development and characterization of LyssaVax, a vaccine featuring a structurally designed, functional chimeric glycoprotein (G) containing immunologically important domains from both RABV G and the highly divergent Mokola virus (MOKV) G. LyssaVax elicits high titers of antibodies specific to both RABV …

Virus-Like Particle-Based Vaccines Induce Antibody-Mediated Neutralization Of Staphylococcus Aureus Virulence, Jason Alexander Joyner
Biomedical Sciences ETDs
Staphylococcus aureus is a pathogenic bacterium that inflicts a large amount of human suffering using an arsenal of virulence factors to cause minor to life-threatening infections. Both the accessory gene regulator (agr) operon, a virulence regulatory pathway that controls expression of over 200 virulence factors, and alpha-hemolysin (Hla), a key pore-forming toxin, play a significant role in infection severity. Given the clinical trial failures of S. aureus vaccine candidates and the prevalence of antibiotic-resistant strains, novel and effective treatment options are urgently needed. Chapter 2 describes a novel virus-like particle (VLP) -based vaccine inducing agr-I-inhibiting antibodies …
Isotype-Specific Outcomes In Fc Gamma Receptor Targeting Of Pspa Using Fusion Proteins As A Vaccination Strategy Against Streptococcus Pneumoniae Infection, Kari Wiedinger
Seton Hall University Dissertations and Theses (ETDs)
Streptococcus pneumoniae (Spn) remains a considerable threat to public health despite the availability of antibiotics and polysaccharide conjugate vaccines. The lack of mucosal immunity in addition to capsular polysaccharide diversity, has proved to be problematic in developing a universal vaccine against Spn. Targeting antigen to Fc receptors is an attractive way to augment both innate and adaptive immunity against mucosal pathogens, by promoting interactions with activating Fcγ receptors (FcγR) that mediate diverse immunomodulatory functions. The effect of targeting FcγR is highly influenced by the IgG subclass, which bares differential affinities for activating and inhibitory FcγR. In the current study we …

Synthesis Of Functionalized Streptococcus Pneumoniae Serotype 6a Di- And Tri- Saccharides, Brady Davis James
Theses and Dissertations
There is a rise in prevalence of antibiotic resistance in Streptococcus pneumoniae, and its FDA-approved vaccines often do not mount effective immune responses in children, the elderly, or the immunocompromised. One reason these vaccines are generally less effective is because they do not utilize T-cell help. T-cell help can be accessed when di-, tri-, or tetra-saccharides positioned inside major histocompatibility complex (MHC) II are presented to T-cell receptors as a target antigen. Pairing MHC II-antigen complexes with T-cell receptors enables development of B and T lymphocytes that are highly specific to these antigens, granting an increase in antibody affinity and …
