Newspaper headlines about polio vaccine tests (April 13, 1955).
The announcement of the polio vaccine's safety and effectiveness was on April 12, 1955, by Dr. Thomas Francis, Jr., of the University of Michigan, the monitor of the test results. Within minutes of his announcement to the audience of scientists and reporters, news of the event was carried coast to coast by wire services and radio and television newscasts. When the vaccine was announced as successful, therefore, it led to spontaneous celebrations across the United States. It was the world's first successful polio vaccine, declared “safe, effective, and potent.”[1] It was possibly the most significant biomedical advance of the past century.[1]
In 1954, the year leading up to the announcement, polio was killing more American children than any other infectious disease. Jonas Salk's vaccine was made ready for its third and final field tests. It became the most elaborate program of its kind in history, involving 20,000 physicians and public health officers, 64,000 school personnel, and 220,000 volunteers.[2] At least one hundred million people had contributed to the March of Dimes, and seven million people had donated their time and labor.[3]:138
Even before the announcement, optimism and hope were so widespread that the Polio Fund in the U.S. had already contracted to purchase enough of the Salk vaccine to immunize 9,000,000 children and pregnant women the following year. And around the world, the official news prompted an immediate international rush to vaccinate.
Test results announced
Clearly a momentous and historic advance in the protection of human wellbeing.
On April 12, 1955, Dr. Thomas Francis, Jr., of the University of Michigan, the monitor of the test results, "declared the vaccine to be safe and effective."[5][6] The announcement was made at the University of Michigan, exactly 10 years to the day after the death of President Roosevelt, who himself was crippled by polio. As the world's first successful polio vaccine, it was declared “safe, effective, and potent.”[1] Some medical experts called it "arguably the most significant biomedical advance of the past century."[1]
Five hundred people, including 150 press, radio, and television reporters, filled the room; 16 television and newsreel cameras stood on a long platform at the back; 54,000 physicians, sitting in movie theaters across the country, watched the broadcast on closed-circuit television.[7]Eli Lilly, a major pharmaceutical company, paid $250,000 to broadcast the event. Americans turned on their radios to hear the details, department stores set up loudspeakers, and judges suspended trials so that everyone in the courtroom could hear. Actor Robert Redford, who was 11-years-old at the time and a victim of polio, called it "earth-shattering news."[8] Europeans listened on the Voice of America.[9]Paul Offit describes the event in a documentary film:
"The presentation was numbing, but the results were clear: the vaccine worked. Inside the auditorium, Americans tearfully and joyfully embraced the results. By the time Thomas Francis stepped down from the podium, church bells were ringing across the country, factories were observing moments of silence, synagogues and churches were holding prayer meetings, and parents and teachers were weeping. One shopkeeper painted a sign on his window: Thank you, Dr. Salk. 'It was as if a war had ended', one observer recalled."[10][11]
"The report," wrote the New York Times, "was a medical classic." Dr. Francis reported that the vaccinations had been 80 to 90 percent effective on the basis of results in eleven states. Overall, the vaccine was administered to over 440,000 children in forty-four states, three Canadian provinces and in Helsinki, Finland,[2] and the final report required the evaluation of 144,000,000 separate items of information. After the announcement, when asked whether the effectiveness of the vaccine could be improved, Salk said, "Theoretically, the new 1955 vaccines and vaccination procedures may lead to 100 percent protection from paralysis of all those vaccinated."[12]
Initial reactions
Shopkeeper expresses a nation's gratitude for Dr. Salk's discovery (April 13, 1955).
Within minutes of Francis's declaration that the vaccine was safe and effective, the news of the event was carried world-wide by wire services and radio and television newscasts.[citation needed]
These reactions by the public and media were seen as justified due to the history of the disease. At the start of the 20th century, for instance, during the 1914 and 1919 polio epidemics in the United States, physicians and nurses made house-to-house searches to identify all infected persons. Children suspected of being infected were taken to hospitals and the child's family was quarantined until they were no longer potentially infectious, even if it meant they could not go to their child's funeral if the child died in the hospital.[13][14]
New York alone had 9,023 cases in 1916, of which 2,448 (28%) resulted in death and a larger number in paralysis.[3]:136 Over the years, as more states began recording instances of the disease, the numbers of victims grew larger. Nearly 58,000 cases of polio were reported in 1952, with 3,145 people dying and 21,269 left with mild to disabling paralysis.[15]
The "public reaction was to a plague", said historian William O'Neill.[3] Citizens of urban areas were terrified each summer when the epidemic was at its worst. "Apart from the atomic bomb," stated a PBS documentary, "America's greatest fear was polio."[16]
It meant that scientists and political leaders were in a frantic race to prevent or cure the disease. Basil O'Connor, president of the American Red Cross, was tasked by President Roosevelt to do whatever was necessary to see that a vaccine was created. That included allowing the National Foundation for Infantile Paralysis, the primary fundraising organization, to go into debt to help Salk complete his research and testing.[17] O'Connor's devotion to this task became almost obsessive when his daughter, a mother of five, told him that she had contracted the illness, saying, "I've gotten some of your polio."[17] "Salk worked sixteen hours a day, seven days a week, for years," wrote Dennis Denenberg.[18]
Nothing short of the overthrow of the Communist regime in the Soviet Union could bring such rejoicing to the hearths and homes of America as the historic announcement last Tuesday that the 166-year war against paralytic poliomyelitis is almost certainly at an end.
When Salk's vaccine was announced as successful, it led to spontaneous celebrations across the United States: "Business came to a halt as the news spread," states Bookchin.[20]:46[lower-alpha 1][lower-alpha 2] The Eisenhower administration made plans to present Salk a special presidential medal designating him "a benefactor of mankind" in a Rose Garden ceremony.[20]:46
According to O'Neill, April 12 had almost become a national holiday. He recalls:
People observed moments of silence, rang bells, honked horns, blew factory whistles, fired salutes, kept their red lights red in brief periods of tribute, took the rest of the day off, closed their schools or convoked fervid assemblies therein, drank toasts, hugged children, attended church, smiled at strangers, and forgave enemies."[3]:138

Six months before Salk's announcement, optimism and hope were so widespread that the Polio Fund in the United States had already contracted to purchase enough of the Salk vaccine to immunize 9,000,000 children and pregnant women the following year.[23] And around the world, the official news prompted an immediate international rush to vaccinate. Medical historian Debbie Bookchin notes that Israel had committed to the Salk vaccine just days before the final report was released, and soon after, Canada, Sweden, Denmark, Norway, West Germany, the Netherlands, Switzerland, and Belgium all announced plans to either immediately begin polio immunization campaigns using Salk's vaccine or to gear up to quickly do so.[20]:47
By the summer of 1957, over two years later, 100,000,000 doses had been distributed throughout the United States and reported complications were rare. Scientists from other nations reported similar experiences: Denmark, for example, reported only a few cases from 2,500,000 who were vaccinated. Australia reported virtually no polio during her past summer season.[24]
Other countries where the vaccine was not yet in use suffered continued epidemics, however. In 1957, Hungary, for example, reported a severe epidemic requiring emergency international assistance. By the first half of the year they had 713 reported cases and a death rate of 6.6%, and the peak infection months of summer were still ahead. Canada sent a shipment of vaccines to Hungary by a refrigerated plane, and Britain and Sweden sent iron lungs. A few years later, during a polio outbreak in Canada, "masked bandits" stole 75,000 Salk vaccine shots from a Montreal university research center.[25]
Just months after the vaccine's success was announced, American President Eisenhower signed the Polio Vaccination Assistance Act of 1955, to ensure the vaccine would be distributed to the public. As a result, 30 million inoculations were given to children in the United States within a year, leading polio cases to fall by almost half during that time. By 1962, the number of cases had fallen to less than 1,000. In 1965, with total cases having dropped to 121, U.S. Surgeon General Luther Terry called it an "historic triumph of preventive medicine — unparalleled in history."[26] In 1979 the United States was declared polio-free.[27]
Globally, by the end of 1990 an estimated 500,000 annual cases worldwide of paralysis were prevented as result of the polio vaccine immunization programs carried out by WHO, UNICEF, and many other organizations.[28] In developing countries, estimates ran as high as 350,000 cases each year in 1988.[28] As a result, in 2002, more than 500 million children were immunized in 93 countries, and by December 2002, there were only 1,924 cases worldwide, mainly in India.[14][29]
Notes
↑ The mayor of New York City interrupted a city council meeting to announce the news, adding, 'I think we are all quite proud that Dr. Salk is a graduate of City College.'"[20]:46
↑ By the next morning, "politicians around the country were falling over themselves trying to figure out ways they could congratulate Salk."[20]:46
↑ The governor of Pennsylvania had a medal struck, and the state legislature gave him a chaired professorship. However, New York City could not get him to accept a ticker-tape parade. Instead New York created eight "Jonas Salk Scholarships" for future medical students.[3]:138
↑ Overnight "Salk had become an international hero and a household name. His vaccine was a modern medical miracle," writes Bookchin.[20]:47
↑ By July, movie studios were already fighting for the motion-picture rights to Salk's film biography. Twentieth Century-Fox began writing a screenplay, and Warner Brothers filed a claim to the title The Triumph of Dr. Jonas Salk shortly after the formal announcement of the vaccine.[21]
↑ A Google Doodle was created on what would have been Salk's 100th birthday, illustrating the day of the vaccine announcement.[22]

Poliomyelitis, commonly shortened to polio, is an infectious disease caused by the poliovirus. Approximately 70% of cases are asymptomatic; mild symptoms which can occur include sore throat and fever; in a proportion of cases more severe symptoms develop such as headache, neck stiffness, and paresthesia. These symptoms usually pass within one or two weeks. A less common symptom is permanent paralysis, and possible death in extreme cases. Years after recovery, post-polio syndrome may occur, with a slow development of muscle weakness similar to that which the person had during the initial infection.
Polio vaccines are vaccines used to prevent poliomyelitis (polio). Two types are used: an inactivated poliovirus given by injection (IPV) and a weakened poliovirus given by mouth (OPV). The World Health Organization (WHO) recommends all children be fully vaccinated against polio. The two vaccines have eliminated polio from most of the world, and reduced the number of cases reported each year from an estimated 350,000 in 1988 to 33 in 2018.
March of Dimes is a United States nonprofit organization that works to improve the health of mothers and babies. The organization was founded by President Franklin D. Roosevelt in 1938, as the National Foundation for Infantile Paralysis, to combat polio. The name "March of Dimes" was coined by Eddie Cantor. After funding Jonas Salk's polio vaccine, the organization expanded its focus to the prevention of birth defects and infant mortality. In 2005, as preterm birth emerged as the leading cause of death for children worldwide, research and prevention of premature birth became the organization's primary focus.
Albert Bruce Sabin was a Polish-American medical researcher, best known for developing the oral polio vaccine, which has played a key role in nearly eradicating the disease. In 1969–72, he served as the president of the Weizmann Institute of Science in Israel.
Pulse Polio is an immunisation campaign established by the government of India to eliminate poliomyelitis (polio) in India by vaccinating all children under the age of five years against the polio virus. The project fights polio through a large-scale, pulse vaccination programme and monitoring for poliomyelitis cases.
Vaccination and religion have interrelations of varying kinds. No major religion prohibits vaccinations, and some consider it an obligation because of the potential to save lives. However, some people cite religious adherence as a basis for opting to forego vaccinating themselves or their children. Many such objections are pretextual: in Australia, anti-vaccinationists founded the Church of Conscious Living, a "fake church", leading to religious exemptions being removed in that country, and one US pastor was reported to offer vaccine exemptions in exchange for online membership of his church.
Cutter Laboratories was a family-owned pharmaceutical company located in Berkeley, California, founded by Edward Ahern Cutter in 1897. Cutter's early products included anthrax vaccine, hog cholera virus, and anti-hog cholera serum—and eventually a hog cholera vaccine. The hog cholera vaccine was the first tissue culture vaccine, human or veterinary, ever produced. The company expanded considerably during World War II as a consequence of government contracts for blood plasma and penicillin. After Edward Cutter's death, his three sons—Dr. Robert K. Cutter (president), Edward "Ted" A. Cutter Jr. (vice-president), and Frederick A. Cutter—ran the company. In the next generation Robert's son David followed his father as president of the company. The Bayer pharmaceutical company bought Cutter Laboratories in 1974.
Polio eradication, the permanent global cessation of circulation by the poliovirus and hence elimination of the poliomyelitis (polio) it causes, is the aim of a multinational public health effort begun in 1988, led by the World Health Organization (WHO), the United Nations Children's Fund (UNICEF) and the Rotary Foundation. These organizations, along with the U.S. Centers for Disease Control and Prevention (CDC) and The Gates Foundation, have spearheaded the campaign through the Global Polio Eradication Initiative (GPEI). Successful eradication of infectious diseases has been achieved twice before, with smallpox in humans and rinderpest in ruminants.
The history of polio (poliomyelitis) infections began during prehistory. Although major polio epidemics were unknown before the 20th century, the disease has caused paralysis and death for much of human history. Over millennia, polio survived quietly as an endemic pathogen until the 1900s when major epidemics began to occur in Europe. Soon after, widespread epidemics appeared in the rest of the world. By 1910, frequent epidemics became regular events throughout the developed world primarily in cities during the summer months. At its peak in the 1940s and 1950s, polio would paralyze or kill over half a million people worldwide every year.
Mass vaccination is a public policy effort to vaccinate a large number of people, possibly the entire population of the world or of a country or region, within a short period of time. This policy may be directed during a pandemic, when there is a localized outbreak or scare of a disease for which a vaccine exists, or when a new vaccine is invented.
In 1976, an outbreak of the swine flu, influenza A virus subtype H1N1 at Fort Dix, New Jersey caused one death, hospitalized 13, and led to a mass immunization program. After the program began, the vaccine was associated with an increase in reports of Guillain–Barré syndrome (GBS), which can cause paralysis, respiratory arrest, and death. The immunization program was ended after approximately 25% of the population of the United States had been administered the vaccine.
Jonas Edward Salk was an American virologist and medical researcher who developed one of the first successful polio vaccines. He was born in New York City and attended the City College of New York and New York University School of Medicine.
Herbert Spencer Ratner, was an American physician. He taught and wrote on the philosophy and history of medicine and was a popular lecturer on marriage and the family. Ratner was the director of public health for the community of Oak Park, Illinois, for twenty-five years. An advocate of preventive family medicine based on natural norms, he was also a long-time proponent of informed medical consent, and played a pivotal role in the polio vaccine controversy beginning in 1955. For more than twenty-nine years Ratner was editor of Child and Family Quarterly, a paramedical journal which ran articles on the Hippocratic Oath, infant development, women’s health, and other topics related to family health.
Polio epidemics were a concern during the summer months for children globally, with records of polio from the Egyptians and Greeks to the 1950s epidemics. Two U.S. virologists, Jonas Salk of the University of Pittsburgh and Albert B. Sabin of the University of Cincinnati emerged as the most prominent among dozens of American researchers on the quest for a polio vaccine.

The 1916 New York City polio epidemic was an infectious disease epidemic of polio ultimately infecting several thousand people, and killing over two thousand, in New York City, primarily in the borough of Brooklyn. The epidemic was officially announced in June 1916, and a special field force was assembled under the authority of Dr. Simon R. Blatteis of the New York City Health Department's Bureau of Preventable Diseases, with broad authority to quarantine those infected with polio and institute hygiene measures thought to slow the transmission of the disease. Polio was a poorly understood disease in this era, and no polio vaccine existed at this time. Official efforts to stem its spread consisted primarily of quarantines, the closure of public places, and the use of chemical disinfectants to cleanse areas where the disease had been present. Special polio clinics were established at various locations in the city for the treatment and quarantine of patients.
Vaccination policy in the United States is the subset of U.S. health policy that deals with immunization against infectious disease. It is decided at various levels of the government, including the individual states. This policy has been developed over the approximately two centuries since the invention of vaccination with the purpose of eradicating disease from the U.S. population, or creating a herd immunity. Policies intended to encourage vaccination impact numerous areas of law, including regulation of vaccine safety, funding of vaccination programs, vaccine mandates, adverse event reporting requirements, and compensation for injuries asserted to be associated with vaccination.
The 1957–1958 Asian flu pandemic was a global pandemic of influenza A virus subtype H2N2 that originated in Guizhou in Southern China. The number of excess deaths caused by the pandemic is estimated to be 1–4 million around the world, making it one of the deadliest pandemics in history. A decade later, a reassorted viral strain H3N2 further caused the Hong Kong flu pandemic (1968–1969).
