Oral vaccines have several advantages compared with parenteral administration: they can be relatively cheap to produce in high quantities, easier to administer, and induce intestinal mucosal immunity that can protect against infection. These characteristics have led to successful use of oral vaccines against rotavirus, polio, and cholera. Unfortunately, oral vaccines for all three diseases have demonstrated lower performance in the highest-burden settings where they are most needed. Rotavirus vaccines are estimated to have >85% effectiveness against hospitalization in children < 12 months in countries with low child mortality, but only ~65% effectiveness in countries with high child mortality. Similarly, oral polio vaccines have lower immunogenicity in developing country settings compared with high-resource settings. Data are more limited for oral cholera vaccines, but suggest lower titers among children compared with adults, and, for some vaccines, lower efficacy in endemic settings compared with non-endemic settings. These disparities are likely multifactorial, and available evidence suggests a role for maternal factors (e.g. transplacental antibodies, breastmilk), host factors (e.g. genetic polymorphisms-with the best evidence for rotavirus-or previous infection), and environmental factors (e.g. gut microbiome, co-infections). Overall, these data highlight the rather ambiguous and often contradictory nature of evidence on factors affecting oral vaccine response, cautioning against broad extrapolation of outcomes based on one population or one vaccine type. Meaningful impact on performance of oral vaccines will likely only be possible with a suite of interventions, given the complex and multifactorial nature of the problem, and the degree to which contributing factors are intertwined.


A Phase 2 Clinical Trial To Evaluate The Safety, Reactogenicity, And Immunogenicity Of Different Prime-Boost Vaccination Schedules Of 2013 And 2017 A(H7n9) Inactivated Influenza Virus Vaccines Administered With And Without As03 Adjuvant In Healthy Us Adults, Christina A Rostad, Robert L Atmar, Emmanuel B Walter, Sharon Frey, Jeffery L Meier, Amy C Sherman, Lilin Lai, Rachel Tsong, Carol M Kao, Vanessa Raabe, Hana M El Sahly, Wendy A Keitel, Jennifer A Whitaker, Michael J Smith, Kenneth E Schmader, Geeta K Swamy, Getahun Abate, Patricia Winokur, Wendy Buchanan, Kaitlyn Cross, Ashley Wegel, Yongxian Xu, Inci Yildirim, Satoshi Kamidani, Nadine Rouphael, Paul C Roberts, Mark J Mulligan, Evan J Anderson Jun 2024

Introduction: A surge of human influenza A(H7N9) cases began in 2016 in China from an antigenically distinct lineage. Data are needed about the safety and immunogenicity of 2013 and 2017 A(H7N9) inactivated influenza vaccines (IIVs) and the effects of AS03 adjuvant, prime-boost interval, and priming effects of 2013 and 2017 A(H7N9) IIVs.

Methods: Healthy adults (n = 180), ages 19-50 years, were enrolled into this partially blinded, randomized, multicenter phase 2 clinical trial. Participants were randomly assigned to 1 of 6 vaccination groups evaluating homologous versus heterologous prime-boost strategies with 2 different boost intervals (21 vs 120 days) and 2 …

Extraintestinal pathogenic Escherichia coli (ExPEC) is a leading cause of worldwide morbidity and mortality, the top cause of antimicrobial-resistant (AMR) infections, and the most frequent cause of life-threatening sepsis and urinary tract infections (UTI) in adults. The development of an effective and universal vaccine is complicated by this pathogen’s pan-genome, its ability to mix and match virulence factors and AMR genes via horizontal gene transfer, an inability to decipher commensal from pathogens, and its intimate association and co-evolution with mammals. Using a pan virulome analysis of >20,000 sequenced E. coli strains, we identified the secreted cytolysin α-hemolysin (HlyA) as a …


Vaccine Hesitancy Among Youth Living With Hiv In Detroit, Madeline B. Simone Mar 2024

Vaccine Hesitancy Among Youth Living With Hiv In Detroit, Madeline B. Simone

Medical Student Research Symposium

Vaccine hesitancy among youth with human immunodeficiency virus (HIV) was evaluated to determine if the pandemic affected vaccine acceptance. A retrospective chart review was conducted to analyze vaccine rates over a five-year (pre-post COVID) in one university-based clinic. Results indicated a variation in acceptance rates between vaccines, with the MenACWY, MenB, tetanus, and HPV having the highest acceptance rates and COVID-19 and annual flu vaccine having the lowest acceptance rates. Vaccine hesitancy did not correlate with HIV treatment hesitancy nor with aversion to needles. Negative messaging around vaccines from a variety of sources appeared to be the primary factor in …


Pseudoviruses, A Safer Toolbox For Vaccine Development Against Enveloped Viruses, Syamala R Thimmiraju, Jason T Kimata, Jeroen Pollet Jan 2024

Pseudoviruses, A Safer Toolbox For Vaccine Development Against Enveloped Viruses, Syamala R Thimmiraju, Jason T Kimata, Jeroen Pollet

Faculty, Staff and Students Publications

Introduction: Pseudoviruses are recombinant, replication-incompetent, viral particles designed to mimic the surface characteristics of native enveloped viruses. They are a safer, and cost-effective research alternative to live viruses. With the potential emergence of the next major infectious disease, more vaccine scientists must become familiar with the pseudovirus platform as a vaccine development tool to mitigate future outbreaks.

Areas covered: This review aims at vaccine developers to provide a basic understanding of pseudoviruses, list their production methods, and discuss their utility to assess vaccine efficacy against enveloped viral pathogens. We further illustrate their usefulness as wet-lab simulators for emerging mutant variants, …

Faculty, Staff and Students Publications

The COVID-19 pandemic triggered a sense of vulnerability and urgency that led to concerted actions by governments, funders, regulators and industry to overcome traditional challenges for the development of vaccine candidates and to reach authorisation. Unprecedented financial investments, massive demand, accelerated clinical development and regulatory reviews were among the key factors that contributed to accelerating the development and approval of COVID-19 vaccines. The rapid development of COVID-19 vaccines benefited of previous scientific innovations such as mRNA and recombinant vectors and proteins. This has created a new era of vaccinology, with powerful platform technologies and a new model for vaccine development. …

Faculty, Staff and Students Publications

Although significant progress has been made in achieving goals for COVID-19 vaccine access, the quest for equity and justice remains an unfinished agenda. Vaccine nationalism has prompted calls for new approaches to achieve equitable access and justice not only for vaccines but also for vaccination. This includes ensuring country and community participation in global discussions and that local needs to strengthen health systems, address issues related to social determinants of health, build trust and leverage acceptance to vaccines, are addressed. Regional vaccine technology and manufacturing hubs are promising approaches to address access challenges and must be integrated with efforts to …

Through the experiences gained by accelerating new vaccines for both Ebola virus infection and COVID-19 in a public health emergency, vaccine development has benefited from a 'multiple shots on goal' approach to new vaccine targets. This approach embraces simultaneous development of candidates with differing technologies, including, when feasible, vesicular stomatitis virus or adenovirus vectors, messenger RNA (mRNA), whole inactivated virus, nanoparticle and recombinant protein technologies, which led to multiple effective COVID-19 vaccines. The challenge of COVID-19 vaccine inequity, as COVID-19 spread globally, created a situation where cutting-edge mRNA technologies were preferentially supplied by multinational pharmaceutical companies to high-income countries while …

BACKGROUND: The continuing evolution of influenza viruses poses a challenge to vaccine prevention, highlighting the need for a universal influenza vaccine. We evaluated the safety and immunogenicity of one such candidate, Multimeric-001 (M-001), when used as a priming vaccine prior to administration of quadrivalent inactivated influenza vaccine (IIV4).

METHODS: Healthy adults 18 to 49 years of age were enrolled in a phase 2 randomized, double-blind placebo-controlled trial. Participants received two doses of either 1.0-mg M-001 or saline placebo (60 per study arm) on Days 1 and 22 followed by a single dose of IIV4 on about Day 172. Safety, reactogenicity, …

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 …

Department of Paediatrics and Child Health

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant of concern comprises several sublineages, with BA.2 and BA.2.12.1 having replaced the previously dominant BA.1 and with BA.4 and BA.5 increasing in prevalence worldwide. We show that the large number of Omicron sublineage spike mutations leads to enhanced angiotensin-converting enzyme 2 (ACE2) binding, reduced fusogenicity, and severe dampening of plasma neutralizing activity elicited by infection or seven clinical vaccines relative to the ancestral virus. Administration of a homologous or heterologous booster based on the Wuhan-Hu-1 spike sequence markedly increased neutralizing antibody titers and breadth against BA.1, BA.2, BA.2.12.1, BA.4, and …

Vaccine Hesitancy And Betrayal Aversion, Abdelaziz Alsharawy, Esha Dwibedi, Jason Aimone, Sheryl Ball Jul 2022

Vaccine Hesitancy And Betrayal Aversion, Abdelaziz Alsharawy, Esha Dwibedi, Jason Aimone, Sheryl Ball

Faculty, Staff and Student Publications

The determinants of vaccine hesitancy remain complex and context specific. Betrayal aversion occurs when an individual is hesitant to risk being betrayed in an environment involving trust. In this pre-registered vignette experiment, we show that betrayal aversion is not captured by current vaccine hesitancy measures despite representing a significant source of unwillingness to be vaccinated. Our survey instrument was administered to 888 United States residents via Amazon Mechanical Turk in March 2021. We find that over a third of participants have betrayal averse preferences, resulting in an 8-26% decline in vaccine acceptance, depending on the betrayal source. Interestingly, attributing betrayal …


The Combination Of Tlr7/8 And Tlr4 Adjuvants In An Influenza Vaccine Produce Unique Antigen-Specific Adaptive Immunity And Protect Against Lethal Heterologous Influenza Challenge, Shelby Lynn Cole Jan 2022

The Combination Of Tlr7/8 And Tlr4 Adjuvants In An Influenza Vaccine Produce Unique Antigen-Specific Adaptive Immunity And Protect Against Lethal Heterologous Influenza Challenge, Shelby Lynn Cole

Graduate Student Theses, Dissertations, & Professional Papers

Influenza virus infection is a global health concern resulting in death and illness each year, which disproportionally effects high-risk individuals. While there are several approved vaccines for seasonal influenza, there are some limitations to consider: current vaccines provide minimal cross protection against seasonally drifted influenza subtypes, influenza vaccine strains change each year, requiring timely manufacture of a new vaccine. Thus, vaccines capable of inducing a more robust and broadly protective immune response to multiple influenza subtypes remains a critical unmet need. Adjuvants and novel delivery systems are an interesting and promising avenue of exploration for enhancing and broadening seasonal influenza …

Creation Of A Global Vaccine Risk Index, Tasmiah Nuzhath, Peter J Hotez, Ashish Damania, P Shuling Liu, Brian Colwell

Center for Medical Ethics and Health Policy Staff Publications

The World Health Organization has identified vaccine hesitancy as one of its top ten global health threats for 2019. Efforts are underway to define the factors responsible for reductions in vaccine confidence. However, as global measles cases accelerated beginning in 2018, it became evident that additional factors were promoting measles re-emergence, including war, political and socio-economic collapse, shifting poverty, and vulnerability to weather events and climate change. Accordingly, we propose a Global Vaccine Risk Index (VRI) to consider these variables as a more comprehensive means to identify vulnerable nations where we might expect measles and other vaccine-preventable diseases to emerge …

BACKGROUND: Typhoid fever is a major public health problem in low-resource settings. Vaccination can help curb the disease and might reduce transmission. We have previously reported an interim analysis of the efficacy of typhoid conjugate vaccine (TCV) in Nepali children. Here we report the final results after 2 years of follow-up.

METHODS: We did a participant-masked and observer-masked individually randomised trial in Lalitpur, Nepal, in which 20 019 children aged 9 months to younger than 16 years were randomly assigned in a 1:1 ratio to receive a single dose of TCV (Typbar TCV, Bharat Biotech International, India) or capsular group …


The Intellectual Property Of Covid-19, Ana Santos Rutschman Jan 2021

The Intellectual Property Of Covid-19, Ana Santos Rutschman

All Faculty Scholarship

The response to COVID-19 is indissolubly tied to intellectual property. In an increasingly globalized world in which infectious disease pathogens travel faster and wider than before, the development of vaccines, treatments and other forms of medical technology has become an integral part of public health preparedness and response frameworks. The development of these technologies, and to a certain extent the allocation and distribution of resulting outputs, is informed by intellectual property regimes. These regimes influence the commitment of R&D resources, shape scientific collaborations and, in some cases, may condition the widespread availability of emerging technologies. As seen throughout this chapter, …

On September 1, 2020 the National Academies released a draft framework for Equitable Allocation of a COVID-19 Vaccine. In this response, we analyze the proposed framework and highlight several areas.

Among the proposed changes, we highlight the need for the following interventions. The final framework for distribution of COVID-19 vaccines should give a higher priority to populations made most vulnerable by the social determinants of health. It should incorporate more geography-based approaches in at least some of the four proposed phases of vaccine distribution. It should address the possibility of a vaccine being made available through an emergency use authorization …

The case-control methodology is frequently used to evaluate vaccine effectiveness post-licensure. The results of such studies provide important insight into the level of protection afforded by vaccines in a 'real world' context, and are commonly used to guide vaccine policy decisions. However, the potential for bias and confounding are important limitations to this method, and the results of a poorly conducted or incorrectly interpreted case-control study can mislead policies. In 2012, a group of experts met to review recent experience with case-control studies evaluating vaccine effectiveness; we summarize the recommendations of that group regarding best practices for data collection, analysis, …

Case-control studies are commonly used to evaluate effectiveness of licensed vaccines after deployment in public health programs. Such studies can provide policy-relevant data on vaccine performance under 'real world' conditions, contributing to the evidence base to support and sustain introduction of new vaccines. However, case-control studies do not measure the impact of vaccine introduction on disease at a population level, and are subject to bias and confounding, which may lead to inaccurate results that can misinform policy decisions. In 2012, a group of experts met to review recent experience with case-control studies evaluating the effectiveness of several vaccines; here we …
