All rights reserved SPRING BOOKS COMMENT protocols and resumption of vaccination meant that six years after the vaccine was introduced, polio was almost eradicated in the United States. Much of the scientific establishment closed ranks against Salk. He was given the prestigious Lasker Award for clinical medi- cal research in 1956, but Swedish virologist Sven Gard dealt his Nobel nomination a fatal blow by sneering that the vaccine was a technical advance, not a discovery. Nor was Salk elected to the US National Acad- emy of Sciences. Virologist Albert Sabin — bombastic, imperious and galled by Salk’s success — continued to develop a live, orally delivered poliovirus preparation. By 1961, Sabin’s vaccine had performed well in trials and the American Medical Asso- ciation began to promote it. Salk’s vaccine was, for a time, superseded, and his efforts to improve its potency stymied. Salk moved on, although he remained involved with the polio vaccine. Influenced by chemist C. P. Snow’s 1959 book The Two Cultures and the Scientific Revolution, he launched a research institute integrating social responsibility and the humanities with the biological sciences. The Salk Insti- tute recruited some of the great biologists of the time, including Jacob Bronowski, Francis Crick and Jacques Monod. But Salk was unable to translate his lofty ideals into practical management. His research from the 1960s onwards, on immune responses in cancer, multiple sclerosis and, PHYSICS later, HIV/AIDS, met with ambivalence. He was increasingly derided by the very scientists whom he had recruited. In many ways, Salk was ahead of his One hundred years of time, notably in public engagement and in his multidisciplinary agenda.

  • A Guide to Preparing Multiple Choice Items
    A Guide to Preparing Multiple Choice Items Introduction The most commonly used type of test item in admissions, certification, and licensure examinations is the multiple choice item. The purpose of this guide is to assist test developers and representatives of professional associations in becoming more skilled in writing multiple choice test items. Preparing multiple choice items may appear on the surface to be a relatively simple task, given familiarity with the subject matter. However, experienced test authors find that this task actually requires a great deal of skill, patience, and creativity. In the sections that follow, general knowledge is used as the content of the examples, in order to facilitate understanding of the principles by professionals from diverse content areas. The skills needed for writing quality items are similar regardless of content discipline. Like any other skill, multiple choice item writing requires a significant amount of painstaking practice with appropriate feedback. It is essential that you try out your multiple choice items on others. This process will help you to uncover ambiguities in wording and unintended violations of item writing principles. Feedback from others will greatly enhance your item writing quality and productivity. Parts of the Multiple Choice Item All multiple choice items consist of two basic parts: the stem and the responses. The stem is the introductory statement or question that elicits the correct answer. The responses are suggested answers which complete the statement or answer the question asked in the stem, only one of which is the correct answer. In the examples that follow, four responses (i.e., 1 correct response and 3 incorrect responses) are presented.

  • Jonas Salk at the National Press Club, April 12, 1965
    Jonas Salk at the National Press Club, April 12, 1965 Jonas Salk, May 1962. A.F.P. – D.P.A. Photos. National Press Club Archives On the tenth anniversary of the licensing of the polio vaccine he developed, Dr. Jonas E. Salk (1914-1995) visited Washington to accept a joint congressional resolution that hailed the vaccine as “one of the most significant medical achievements of our time.” At the White House, President Johnson offered Salk his congratulations. The day also marked the twentieth anniversary of the death of former President Franklin D. Roosevelt, who, having suffered from paralytic polio since 1921, had established the foundation that funded Salk’s efforts. Following his meetings with Congress and the President, Salk gave a talk and answered reporters’ questions at a National Press Club luncheon. In the title of its lead editorial ten years earlier celebrating the successful testing of the new vaccine, the New York Times proclaimed the “Dawn of a New Medical Day.” Testing of the vaccine, like the funding for its development, had engaged the participation of millions of ordinary American citizens. Through March of Dimes campaigns, hundreds of thousands of volunteers went door-to-door raising $41 million in 1952 alone from average donations of 27 cents. The tests involved 1.8 million school children, 200,000 volunteers, 64,000 teachers, and 60,000 physicians, nurses, and health officials, making it the largest clinical trial in history. Interpreting the jubilant 1 reaction to news that the vaccine had been proven safe and effective, the Times commented, “Gone are the old helplessness, the fear of an invisible enemy, the frustration of physicians.” Poliomyelitis, also known as infantile paralysis, is an extremely contagious viral infection caused by any of three types of poliovirus.

Lee San Marcos, Texas December, 2005 Insert signature page here ii COPYRIGHT By Jason Chu Lee 2005 iii ACKNOWLEDGEMENTS It leaves me in a stupor to contemplate all those I have to thank for aiding me in this effort. If I leave anybody out, please accept my most humble apologies, as the list is long. I will be the first to admit that this work is flawed, despite the best efforts of my committee to save me from myself. Had I utilized them more, this piece would only be improved. I had never undertaken a project of this scope before and though I believe I have accomplished much, the experience has been humbling. Never again will I utter the phrase, “just a thesis.” My biggest thanks go out to Dr. Mary Brennan, my committee chair and mentor. Without her guidance I most certainly would have needed to take comprehensive finals to graduate. She helped me salvage weeks of research that I thought had no discernable use. But Dr. Brennan, despite her very, very busy schedule with the department and her family, still found the time to help me find my thesis in all the data. She is well loved in the department for obvious reasons, as she has a gift for being firm and professional while remaining compassionate. Dr. James Wilson and Dr.

Although several vaccines are already available to rich countries, low-income countries face gross vaccine inequity. We propose COVID-19 eradication to address both problems. An eradication program will ensure vaccine equity and international cooperation to establish public health surveillance and high quality laboratory diagnostic services in all countries. Eradication is biologically and technically feasible. We hope the World Health Organization will accept the proposition and design the necessary strategy without delay.

  • The March of Dimes and Polio: Lessons in Vaccine Advocacy for Health Educators
    Feature Article The March of Dimes and Polio: Lessons in Vaccine Advocacy for Health Educators Dawn Larsen ABSTRACT The polio vaccine became available in 1955, due almost entirely to the efforts of the March of Dimes. In 1921, Franklin Roosevelt gave a public face to polio and mounted a campaign to prevent it, establishing the National Foundation for Infantile Paralysis in 1938. During the Depression, U.S. citizens were asked to contribute one dime. Entertainer Eddie Cantor suggested the name the March of Dimes, paraphrasing the popular newsreel “The March of Time.” Jonas Salk advocated a killed-virus vaccine while Albert Sabin proposed a live-virus vaccine. Both competed for both recognition and funding from the March of Dimes. In 1955 Salk’s vaccine was adopted, nationwide vaccination programs were implemented, and polio rates dropped by 80 percent. In 1961, Sabin’s vaccine, endorsed by the American Medical Association, became the vaccine of choice. The World Health Assembly advocated polio eradication by the year 2000. By 2004 eradication efforts were threatened by allegations linking vaccines to chronic diseases. Immunization dropped and polio resurfaced in the U.S., Australia, Africa and Russia. Research linking vaccines to chronic disease was dis- credited, but vaccine opponents remain active. Health educators are well positioned to mitigate damage caused by the anti-vaccine movement and address barriers to immunization efforts. Larsen D.

  • August 2021 Factsheet Access to Vaccines
    ACCESS TO HEALTHCARE AND PRICING ACCESS TO VACCINES GRI Standards : 416-1, 416-2 : Customer Health and Safety EXECUTIVE SUMMARY Vaccines have a great impact on public health. The World Health Organization considers immunization to be one of the most effective and cost-effective health interventions. It has eradicated smallpox, reduced the global incidence of polio by 99% to date,1 and dramatically reduced morbidity, disability and mortality due to diphtheria, tetanus, pertussis, tuberculosis and measles. Despite these important achievements, there is still a long way to go: 19.7 million children worldwide still have no access to a full cycle of basic vaccines.2 Due to lower immunization coverage in some countries, we are witnessing a resurgence of diseases that had almost disappeared, such as measles or pertussis. This affects people around the world, including in high-income countries. True to its vision of a world where no one suffers or dies from a vaccine-preventable disease, Sanofi Pasteur is committed to improve sustainable access to vaccines, with the help of key partnerships to provide effective and affordable vaccines and protection for all populations. This document presents some of our key commitments and initiatives illustrating our longstanding dedication to global access to health through prevention and vaccination. 1 WHO Factsheet on Poliomyelitis, last updated July 2019. https://www.who.int/news-room/fact-sheets/detail/poliomyelitis 2 WHO Factsheet on Immunization, last updated July 2020. https://www.who.int/en/news-room/fact-sheets/detail/immunization-coverage Access to Vaccines Factsheet 1 Published August 2021 TABLE OF CONTENTS 1.

It is a pleasure and privilege to be able to meet with the United States- Mexico Border Public Health Association. Rapid transportation has increased the need for cooperative action in the field of national and international health. The vectors and agents of disease do not respect international boundaries or treaties. 1 have always been impressed by the amicable international relation- ship between doctors, other scientific men and especially public health personnel. The results of this friendly and cooperative attitude have been most beneficial to mankmd. For the three year period 1945 to 1948, the U. S. Army required the inoculation of al1 troops with influenza virus vaccine. The vaccine con- tained 50% Type B (Lee), 25% Type A PR8, and 25% A Prime (Weiss or FMl) strains. The decision to vaccinate was based largely upon the signifkant results obtained in evaluation studies of influenza virus vaccine during 1943 and 1945** 2, 3.
