Public Health At Risk: The Conscious Choice To Refuse Vaccinations Threatens Public Health

DePaul Magazine

Public health officials declared that measles had been eliminated from the United States after only 15 measles cases were reported between 1998 and 2001 and 90 percent of schoolchildren had been inoculated against the disease. Yet, in 2014, there were more than 660 documented measles cases in the country, the most in 20 years. This uptick started in the late 1990s, when a growing number of parents began refusing to inoculate their children with some or all of the recommended vaccines. Various factors fed their decision: an increase in the number of vaccines given in the first year of life, …

A Global Map Of Hemispheric Influenza Vaccine Recommendations Based On Local Patterns Of Viral Circulation, Wladimir J. Alonso, Christine Yu, Cecile Viboud, Stephanie A. Richard, Cynthia Schuck-Paim, Lone Simonsen, Wyller A. Mello, Mark A. Miller

Global Health Faculty Publications

Both the Northern and the Southern Hemisphere annual WHO influenza vaccine recommendations are designed to ensure vaccine delivery before the winter-time peak of viral circulation in each hemisphere. However, influenza seasonal patterns are highly diverse in tropical countries and may be out of phase with the WHO recommendations for their respective hemisphere. We modelled the peak timing of influenza activity for 125 countries using laboratory-based surveillance data from the WHO’s FLUNET database and compared it with the influenza hemispheric recommendations in place. Influenza vaccine recommendations for respectively 25% and 39% of the Northern and Southern Hemisphere countries were out of …

Virus Sharing, Genetic Sequencing, And Global Health Security, Lawrence O. Gostin, Alexandra Phelan, Michael A. Stoto, John D. Kraemer, K. Srinath Reddy

Georgetown Law Faculty Publications and Other Works

The WHO’s Pandemic Influenza Preparedness (PIP) Framework was a milestone global agreement designed to promote the international sharing of biological samples to develop vaccines, while that ensuring poorer countries would have access to those vaccines. Since the PIP Framework was negotiated, scientists have developed the capacity to use genetic sequencing data (GSD) to develop synthetic viruses rapidly for product development of life-saving technologies in a time-sensitive global emergency—threatening to unravel the Framework. Access to GSD may also have major implications for biosecurity, biosafety, and intellectual property (IP).

By rendering the physical transfer of viruses antiquated, GSD may also undermine the …

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 …

Aims -- To assess work absenteeism due to ILIs among privately insured employees in the USA in 2007–8 and 2008–9.

Methods -- We used the 2007–9 MarketScan® research databases. Full-time employees aged 18–64 years, with the ability to incur work absence and continuously enroled in the same insurance plan during each season were included. We identified ILI episodes using ICD-9 codes for influenza and …

Vaccine-Preventable Diseases In Travelers, Edith Mirzaian, Jeffery A. Goad, Ani Amloian, Fady Makar

Pharmacy Faculty Articles and Research

Travel to the developing world is increasing among those from developed countries, placing them at risk for vaccine preventable and non-vaccine preventable diseases. From 2007-2011, the GeoSentinel Network reported 737 returned travelers with a vaccine preventable disease. While it is essential that clinicians use vaccines when available for a disease of risk, they should also be aware that the vast majority of diseases acquired by travelers are non-vaccine preventable. The vaccine preventable diseases can be divided into routine travel vaccines, special travel vaccines and routine vaccines used for travel. The routine travel vaccines include Hepatitis A and B, typhoid; special …

Best Practices: A Network Approach Of The Mandatory Influenza Vaccination Among Healthcare Workers, Greg Attenweiler, Angie Thomure

Master of Public Health Program Student Publications

A network simulation was applied to hospital social networks improve the influenza vaccination rate of healthcare workers in a healthcare system. Social network methods can be used to develop an understanding of structures of social relations. Over 200,000 U.S. patients are hospitalized annually for influenza, which attributes to 36,000 deaths and is the sixth leading cause of death in adults. The best way to prevent influenza each year is by receiving the influenza vaccination. The typical influenza vaccination rate among healthcare workers is 40- 50%. A Healthy People 2020 objective is to increase the percentage of healthcare workers who are …

Development Of Novel Subunit Vaccine Against H5n1 Influenza, Lu Zhang

Graduate Theses and Dissertations

Influenza is a common infectious disease resulting from a frequently mutated RNA virus. Vaccination is currently the most effective method to prevent people from seasonal or pandemic influenza. The production of traditional egg-based influenza vaccine is time-consuming and provides limited effect against new strains. Therefore, it is necessary to develop a rapid method to produce influenza vaccines. We proposed a novel influenza vaccine based on the E.coli expression system. Hemagglutinin (HA) is the major target surface protein of influenza virus for vaccine development. In this study, we sub-cloned the HAs encoding gene into an E. coli expression vector; the signal …

B Cell Response And Hemagglutinin Stalk-Reactive Antibody Production In Different Age Cohorts Following 2009 H1n1 Influenza Virus Vaccination, Mark Y. Sangster, Jane Baer, Felix W. Santiago, Theresa T. Fitzgerald, Natalia A. Ilyushina

Dartmouth Scholarship

The 2009 pandemic H1N1 (pH1N1) influenza virus carried a swine-origin hemagglutinin (HA) that was closely related to the HAs of pre-1947 H1N1 viruses but highly divergent from the HAs of recently circulating H1N1 strains. Consequently, prior ex- posure to pH1N1-like viruses was mostly limited to individuals over the age of about 60 years. We related age and associated dif- ferences in immune history to the B cell response to an inactivated monovalent pH1N1 vaccine given intramuscularly to subjects in three age cohorts: 18 to 32 years, 60 to 69 years, and >70 years. The day 0 pH1N1-specific hemagglutination inhibition (HAI) …

Office of the Provost

Objectives: Effective communication by public health agencies during a pandemic promotes the adoption of recommended health behaviours. However, more information is not always the solution. Rather, attention must be paid to how information is communicated. Our study examines the television news, which combines video and audio content. We analyse (1) the content of television news about the H1N1 pandemic and vaccination campaign in Alberta, Canada; (2) the extent to which television news content conveyed key public health agency messages; (3) the extent of discrepancies in audio versus visual content.
Methods: We searched for "swine flu" and "H1N1" in local English …

In Vitro Characterization Of Avian Influenza Virus Isolates With A Truncated Ns1 Gene Segment, Aaron Dick

Honors Scholar Theses

Avian Influenza Virus represents a significant threat to the world poultry population, and is a potential threat to humans due to the possibility of cross-species AIV infection. Our approach is to characterize a number of avian virus populations with respect to their content of biologically active particles that include hemagglutinating particles (HAP), plaque forming particles (PFP), interferon inducing particles (IFP), interferon induction-suppressing particles (ISP), defective-interfering particles (DIP), cell-killing particles (CKP) and non-infectious cell killing particles (niCKP) using unique in vitro assays developed for avian influenza virus in the Marcus-Sekellick Laboratory. Specifically, we will use a strain of Avian influenza virus, …

An In-Depth Look At Recent Influenza Seasons And Vaccine Effectiveness, Ariana Ricci

Honors Projects in Science and Technology

This paper aims to present an in-depth exploration of immunology, the influenza virus, vaccination, and vaccination’s effectiveness with respect to influenza. It also delves into the possible causes behind the large increase in early childhood deaths during the 2003-2004 influenza season, which was a turning point in terms of influenza incident reporting. Finally, data analysis on the relationship between childhood flu vaccine coverage and childhood outpatient ILI (influenza-like illness) visits by region is presented as a measurement of vaccine effectiveness and identifier of trends. Although this relationship was not statistically significant (alpha=0.05) regionally, this simply points to alternate factors that …

Mortality Burden Of The 2009 A/H1n1 Influenza Pandemic In France: Comparison To Seasonal Influenza And The A/H3n2 Pandemic, Magali Lematire, Fabrice Carrat, Gregoire Rey, Mark A. Miller, Lone Simonsen, Cecile Viboud

Global Health Faculty Publications

Background

The mortality burden of the 2009 A/H1N1 pandemic remains unclear in many countries due to delays in reporting of death statistics. We estimate the age- and cause-specific excess mortality impact of the pandemic in France, relative to that of other countries and past epidemic and pandemic seasons.

Methods

We applied Serfling and Poisson excess mortality approaches to model weekly age- and cause-specific mortality rates from June 1969 through May 2010 in France. Indicators of influenza activity, time trends, and seasonal terms were included in the models. We also reviewed the literature for country-specific estimates of 2009 pandemic excess mortality …

Immunizations For Adults And Children, Lynne J. Goebel, Nancy B. Norton, Maurice A. Mufson

Internal Medicine

Vaccines represent the most important medical advance of the twentieth century. The time has passed when large numbers of children and adults suffered serious, life threatening illness from viruses including poliovirus, measles virus, influenza viruses, hepatitis B virus and varicella zoster virus or faced lifelong disability or death from bacterial infections including Hemophilus influenzae, meningococcus and pneumococcus, all infections that can be prevented now by effective vaccines.

Aptamer-Based Spr Biosensor For Detection Of Avian Influenza Virus, Hua Bai

Graduate Theses and Dissertations

Rapid and specific detection of avian influenza (AI) virus is urgently needed with the concerns over the outbreaks of highly pathogenic H5N1 avian influenza in animal and human infection. Aptamers are artificial oligonucleic acid that can specifically bind to target molecules. They show comparable affinity for target virus and better thermal stability than monoclonal antibodies. Those advantages make aptamers promising candidates in diagnostic and detection applications. The goal of this research was to use DNA&ndashaptamer as the specific recognition element in a portable surface plasmon resonance (SPR) biosensor for detection of AI H5N1 virus in poultry.

A SPR biosensor was …

Independent Study Project (ISP) Collection

Why do two developing countries in the same region have vastly different vaccination rates? What specific factors have the greatest influence on the vaccination rates in differing developing nations? This papers objective is to use a statistical model to try to determine what factors, education, healthcare system and infrastructure, play the largest role in impacting both positively the measles vaccination rate in 20 African countries. The results found only two of the six variables originally chosen to be statistically significant. These variables were the percentage of paved roads and the percentage of the GDP spent on education.

Sick With Fear: Popular Challenges To Scientific Authority In The Vaccine Controversies Of The 21st Century, Ellen Watkins

Annual Undergraduate Conference on Health and Society

In the 20th century, vaccines were heralded as one of the greatest medical inventions in history. In the late 1990’s, however, the myth of vaccine-caused autism caught fire. Despite mountains of evidence disproving the link, panicking Americans eschewed vaccines and turned against their physicians. Why did Americans turn their backs on doctors, scientists, and the health industry? This paper follows the vaccine controversy of the last thirty years, looking in particular at the relationship between science and the media. This paper analyzes the contrast between discussion of the hypothesized link in scientific circles and in popular news sources, seeking to …

Impact Of Haemophilus Influenzae Type B Conjugate Vaccine On Bacterial Meningitis In The Dominican Republic, Ellen H. Lee, Miriam Corcino, Arelis Moore De Peralta, Zacarias Garib, Chabela Peña, Jacquelin Sánchez, Josefina Fernández, Jesús M. Feris-Iglesias, Brendan Flannery

Publications

OBJECTIVES:

Widespread use of Haemophilus influenzae type b (Hib) vaccines has dramatically reduced the burden of Hib disease throughout the Americas. Few studies have evaluated the impact of Hib vaccination on non-culture-confirmed disease. This study analyzed trends in probable bacterial meningitis before and after the introduction of Hib vaccine in the Dominican Republic and estimated vaccine effectiveness against Hib meningitis.

METHODS:

Meningitis cases among children < 5 years of age were identified from admission records of the main pediatric hospital in Santo Domingo during 1998-2004. Laboratory criteria were used to classify meningitis cases with probable bacterial etiology; confirmed cases had positive bacterial culture or antigen detection in cerebrospinal fluid. Cumulative incidence rates of confirmed and probable bacterial meningitis were calculated for children living in the National District. Confirmed cases of Hib meningitis were enrolled in a case-control study with age- and neighborhood-matched control children to calculate vaccine effectiveness.

RESULTS:

Before vaccine introduction, annual rates of meningitis with probable bacterial etiology were 49 cases per 100 000 children < 5 years old; Hib accounted for 60% of confirmed bacterial cases. During 2002-2004, after vaccine introduction, annual rates of probable bacterial meningitis were 65% lower at 16 cases per 100 000, and Hib accounted for 26% of confirmed cases. Rates of Hib meningitis and probable bacterial meningitis with no determined etiology declined by 13 and 17 cases per 100 000, respectively.

CONCLUSIONS:

Introduction of Hib vaccine substantially reduced the incidence of confirmed and probable bacterial meningitis in …
