The Cow Pockorthe Wonderful Effects of the New Inoculation
As long as vaccines have existed, humans have been suspicious of both the shots and those who administer them. The first inoculation deployed in America, against smallpox in the 1720s, was decried as antithetical to Gods will. An outraged citizen tossed a bomb through the window of a house where pro-vaccination Boston minister Cotton Mather lived to dissuade him from his mission.
It did not stop Mathers campaign.
After British physician Edward Jenner developed a more effective smallpox vaccine in the late 1700susing a related cowpox virus as the inoculantfear of the unknown continued despite its success in preventing transmission. An 1802 cartoon, entitled The Cow Pockorthe Wonderful Effects of the New Innoculation, depicts a startled crowd of vaccinees who have seemingly morphed into a cow-human chimera, with the front ends of cattle leaping out of their mouths, eyes, ears and behinds.
Paul Offit, director of the Vaccine Education Center at the Children’s Hospital of Philadelphia, says the outlandish fiction of the cartoon continues to reverberate with false claims that vaccines cause autism, multiple sclerosis, diabetes, or that the messenger RNA-based Covid-19 vaccines from Pfizer/BioNTech and Moderna lead to infertility.
The impact of this particular product, the antitoxin, in the 1890s was huge, she says.
Testing And Licensing Of Sabin Polio Vaccine
For four years, researcher Albert Sabin partnered with health officials from the Soviet Union to produce a more affordable alternative. More than 10 million children received his oral polio vaccine during this period.
Studies showed that Sabins version triggered a faster immune response and was easier to administer than Salks vaccine. Both Salks injectable vaccine and Sabins oral vaccine stopped the spread of all strains of the poliovirus through the bloodstream.
Ultimately, the U.S. Surgeon General recommended licensing of Sabins OPV, which combined vaccinations against all three types of polio in 1963.
In the decades that followed, widespread use of the polio vaccine finally began to stem the tide of this contagious disease. The World Health Organization would later launch a global poliovirus eradication program in the 80s.
A Brief History Of Vaccination
The practice of immunisation dates back hundreds of years. Buddhist monks drank snake venom to confer immunity to snake bite and variolation was practiced in 17th century China. Edward Jenner is considered the founder of vaccinology in the West in 1796, after he inoculated a 13 year-old-boy with vaccinia virus , and demonstrated immunity to smallpox. In 1798, the first smallpox vaccine was developed. Over the 18th and 19th centuries, systematic implementation of mass smallpox immunisation culminated in its global eradication in 1979.
Louis Pasteurs experiments spearheaded the development of live attenuated cholera vaccine and inactivated anthrax vaccine in humans . Plague vaccine was also invented in the late 19th Century. Between 1890 and 1950, bacterial vaccine development proliferated, including the Bacillis-Calmette-Guerin vaccination, which is still in use today.
In 1923, Alexander Glenny perfected a method to inactivate tetanus toxin with formaldehyde. The same method was used to develop a vaccine against diphtheria in 1926. Pertussis vaccine development took considerably longer, with a whole cell vaccine first licensed for use in the US in 1948.
Viral tissue culture methods developed from 1950-1985, and led to the advent of the Salk polio vaccine and the Sabin polio vaccine. Mass polio immunisation has now eradicated the disease from many regions around the world

The History Of Covid Vaccine Development

A Brief History Of The Flu Vaccine
Every year, three to five million people catch the seasonal flu, according to the World Health Organization , and between 290,000 and 650,000 people die from it worldwide. Still, thanks to the flu vaccine, this is only a fraction of how many people it used to kill. During the last major flu pandemic of 1918-1919, it killed between 50 and 100 million people around the world.
For a long time, scientists had thought that the flu was caused by a bacteria called Haemophilus influenzae, but after the 1918-19 pandemic, they started to suspect it was caused by a virus instead. However, it wouldnt be until the 1930s that they would confirm that. In 1933, three scientists isolated the Influenza A virus in ferrets one of the three types of flu and in 1936, it was discovered that the virus could be grown inside embryonated chicken eggs, a key step towards making a vaccine.
Just two years later, in 1938, Jonas Salk and Thomas Francis developed the first vaccine using fertilized chicken eggs and an inactivated strain of the Influenza A virus.
This new vaccine was first used to help protect soldiers fighting in World War II it wouldnt be approved for civilians until 1946. According to a 1944 study of the new vaccine, it helped reduce illness that was accompanied by a temperature above 99 degrees Fahrenheit.

Jenner Didn’t Seek To Make Any Money From His Vaccine He Wasn’t Interested In Patenting It Owen Gower
Nevertheless, Jenner realised that his smallpox vaccine the name derived from the Latin for cowpox, vaccinia had the potential to transform medicine and save lives. But he also knew he would only halt the disease if he could vaccinate as many people as possible.
Jenner didn’t seek to make any money from his vaccine, he wasn’t interested in patenting it, says Gower. He just wanted people to know about it and he wanted to share it.
He converted a rustic summerhouse in his garden into his Temple of Vaccinia and invited local people to be vaccinated after church on Sunday.
He wrote to other physicians offering them samples of the vaccine material and encouraging them to do it themselves so that people were vaccinated by their own local trusted health professional, Gower says. It’s a theme that we see now in terms of vaccine advocacy and ensuring acceptance of a vaccine is the right message delivered by the right person.
In the 19th Century, smallpox is thought to have killed 400,000 people a year in Europe alone
After Jenner published his findings, news of the discovery spread across Europe. And then, thanks to the support of the King of Spain, around the world.
In 1803, the ship sailed for South America. On board were 22 orphans to act as vaccine carriers.
The children were cared for on the journey by the orphanage director, Isabel de Zendala y Gomez, who also brought along her own son to contribute to the mission.

The Vaccine Life Cycle: Safety At Every Phase
Safety is a Priority During Vaccine Development and Approval
Before vaccines are licensed by the FDA, they are tested extensively in the laboratory and with human subjects to ensure their safety. First, researchers use computers to predict how the vaccine will interact with the human immune system. Then researchers test the vaccine on animals including mice, guinea pigs, rabbits, and monkeys.
Vaccine development and approval follows the same general pathway as for drugs and other biologics. A sponsor who wishes to begin clinical trials with a vaccine must submit an Investigational New Drug application to FDA. The IND describes the vaccine, its method of manufacture, and quality control tests for release. Also included are information about the vaccines safety and ability to elicit a protective immune response in animal testing, as well as a proposed plan for testing the drug on humans.

Vaccine licensing is a lengthy process that can take 10 years or longer. The FDA requires that vaccines undergo three phases of clinical trials with human subjects before they can be licensed for use in the general public:

Mid Twentieth And Twenty
In 1966, the World Health Assembly called for global smallpox eradication, which was launched the following year. During the first year of the program 217,218 cases of polio were reported in 31 countries that were endemic to smallpox. Four years later, the CDC recommended discontinuation of routine vaccination for smallpox in the U.S. following a greatly reduced risk of disease .
During the 70s, especially in 1974, the Expanded Program on Immunization was created within WHO, in response to poor immunization levels in developing countries . The following vaccines were used by the Expanded Program on Immunization: BCG, Polio, DTP, measles , yellow fever , and hepatitis B. Three years later, in October 1977, the last case of naturally acquired smallpox occurred in the Merca District of Somalia. In the same year, the first pneumococcal vaccine was licensed, containing 14 serotypes that composed 80% of all bacteremic pneumococcal infections in the U.S. .
During the year 1994, The Expanded Program for Vaccine Development and the Vaccine Supply and Quality Program were merged creating the Global Program for Vaccines and Immunization. During the same year, the Western Hemisphere was finally labeled as polio-free by the International Commission for the Certification of Polio-Eradication.
The Fifties: Influenza Mismatchand Influenza Surveillance
The first system for the surveillance of circulating influenza virus strains in several countries worldwide was created in 1952 by the World Health Organization in order to monitor the various virus mismatches reported. This important innovative tool enabled the composition of seasonal influenza vaccines to be determined on the basis of the epidemiology of influenza in the previous season . In 1946, as a result of viral mutation, a new variant of influenza A , A/FM/1/47, appeared in Australia. This gave rise to a new influenza subtype, the H2N2 strain, which caused the pandemic known as Asian flu .
The following year, the US Commission on Influenza recommended that a representative of this strain be included in subsequent vaccines.
The emergence of an HA subtype different from those circulating in previous seasons determined the need for pandemic influenza vaccines .

Polio Vaccine History: Timeline Of Poliomyelitis Discovery And Vaccine Invention
Polio is a serious viral infection that was globally prevalent before the 1980s. Thankfully, its groundbreaking vaccine essentially eradicated it in most parts of the world. Join Flo as we explore the history of polio as well as the scientists who discovered the polio vaccine.
The Long History Of Mrna Vaccines
Messenger RNA, or mRNA, was discovered in the early 1960s research into how mRNA could be delivered into cells was developed in the 1970s. So, why did it take until the global COVID-19 pandemic of 2020 for the first mRNA vaccine to be brought to market?
In this explainer, Chris Beyrer talks us through mRNA vaccines history, development, and breakthroughs.
Theres a big gap between when the first mRNA flu vaccine was tested in mice in the 1990s and when the first mRNA vaccines for rabies were tested in humans in 2013. What was happening in the interim?
The early years of mRNA research were marked by a lot of enthusiasm for the technology but some difficult technical challenges that took a great deal of innovation to overcome.
The biggest challenge was that mRNA would be taken up by the body and quickly degraded before it could deliver its messagethe RNA transcriptand be read into proteins in the cells.
The solution to this problem came from advances in nanotechnology: the development of fatty droplets that wrapped the mRNA like a bubble, which allowed entry into the cells. Once inside the cell, the mRNA message could be translated into proteins, like the spike protein of SARS-CoV-2, and the immune system would then be primed to recognize the foreign protein.
So, what happened once they figured out this technology?
Then COVID-19 hit what happened then?

How Many People Have Been Vaccinated For Covid
Despite global efforts to distribute the covid-19 vaccines, access remains much higher in richer countries versus poorer ones. Overall, more than 8 billion shots have been administered globally and around 55% of the world population has received at least one dose, but the rate is much lower in poor countries: barely above 6%.
In the months after covid-19 vaccines first hit the market, many rich countries hoarded them. While they have since pledged more doses to poor countries through the global Covax initiative, the program announced in September it would fall 30% short of its promise to deliver 2 billion shots this year. More than 80% of people in Africa remain unvaccinated, and even as more shots arrive to the continent, ongoing logistical challenges and vaccine hesitancy are complicating rollouts of these campaigns.
At the same time, some countries with ample vaccine access are struggling to hit their targets. About 60% of Americans have been fully vaccinated for covid-19, one of the lowest rates of any G7 nation. Germany, Austria, and the German-speaking region of Switzerland had the largest shares of unvaccinated populations in all of western Europe as of last month.
Annual Updates To The Immunization Schedule 1995 To 2010
As more vaccines became available, an annual update to the schedule was important because of changes that providers needed to know, such as detailed information about who should receive each vaccine, age of receipt, number of doses, time between doses, or use of combination vaccines. New vaccines were also added.
Important changes to the schedule between 1995 and 2010 included:
- New vaccines: Varicella , rotavirus hepatitis A pneumococcal vaccine
- Additional recommendations for existing vaccines: influenza hepatitis A
- New versions of existing vaccines: acellular pertussis vaccine intranasal influenza
- Discontinuation of vaccine: Oral polio vaccine

When Were Vaccines Invented
When looking atthe history of vaccines timeline you can start in 15th centuryChina. The Chinese recognized that people who survived smallpox did not getthe disease again. They decided to take smallpox scabs from people who had mildcases, dry them out, grind them into a powder and blow the powder up the nostrilsof healthy people. The effectiveness of these early vaccination efforts is notwell-known, but they had the right idea: taking a weaker version of the virus,and introducing it to healthy people to allow their immune system to build upantibodies .
Edward Jenner Takes On Smallpox
If the Chinese were first out of the gate in attempting to develop a vaccine against smallpox, it is 18th century British physician Edward Jenner who is credited with developing the first safe and reliable version.
Jenner, like others of his time, had noticed that milkmaids who as a result of their work had contracted cases of cowpox, a disease that could be transferred from cattle to humans, would typically be spared smallpox infection whenever there was a local outbreak. Cowpox was apparently dissimilar enough from smallpox to cause only comparatively mild symptoms in people but similar enough to confer immunity against the human form of the disease.
In a celebrated experiment in 1796though it would hardly pass ethical muster todayJenner harvested bits of a cowpox pustule from a milkmaid named Sarah Nelmes and scratched it into the arm of an 8-year-old boy named James Phipps, on May 14, 1796.
After, he attempted to infect Phipps with human smallpox, but the boy simply shook off the virus. Two year later, Jenner published his results in a book that went by the less-than-reader-friendly title An inquiry into the causes and effects of the variolae vaccinae: a disease discovered in some of the western counties of England, particularly Gloucestershire, and known by the name of the cow pox. Still, the contentif not the marketing planwas a sensation. By 1801, an estimated 100,000 people had been vaccinated using the same method.

A History Of Influenza: From The Classicalperiod To The Nineteenth Century
In 412 BC, in the “Book of Epidemics”, Hippocrates described a putative influenza-like illness syndrome called “fever of Perinthus” or “cough of Perinthus” . While some scholars claim that this is probably the first historical description of influenza , others, including the notable 19th-century editor of Hippocrates, Émile Littré , think that a diagnosis of diphtheria would better fit the description of complications . On the other hand, symptoms such as disturbed vision and night blindness suggest a combination of diseases, including deficiency syndromes . In the years 1173 and 1500, two other influenza outbreaks were described, though in scant detail . The name “influenza” originated in the 15th century in Italy, from an epidemic attributed to the “influence of the stars”, which, according to Ginctrac, raged across Europe and perhaps in Asia and Africa .
It seems that influenza also reached the Americas. Scholars and historians debate whether influenza was already present in the New World or whether it was carried by contaminated pigs transported on ships. Some Aztec texts speak of a “pestilential catarrh” outbreak in 1450-1456 in an area now corresponding to Mexico, but these manuscripts are difficult to interpret correctly and this hypothesis seems controversial .
