The History of the Polio Vaccine

On May 2, 1921, the United States entered World War I, the longest peacetime conflict in US history.

The US had already been engaged in World War II and the first year of World War Two had been a very bitter one.

In the spring of 1921, President Herbert Hoover ordered the creation of a federal polio vaccination program, which was initially intended to include all US citizens.

In November, the US was finally granted full vaccine eligibility for the first time.

But even as the country was preparing for the vaccine, polio was still a problem.

A staggering 7.3 million Americans were infected, making it the third most deadly infectious disease in the US behind influenza and measles.

This year marks the 25th anniversary of the first vaccination, and we look back on how the polio vaccine came to be.

We look at how the US first polio vaccine was developed and what the US had to do to make it more effective.

The first polio vaccination in the United State In 1916, a small team of doctors from Boston University and Boston College administered a vaccine to all American schoolchildren in New England.

In addition to vaccination, the vaccine was designed to help the people of the US learn how to safely use the vaccine and also to help prevent the spread of the disease.

After being tested for years, the new vaccine was approved by the US Food and Drug Administration in September 1917.

In 1918, the first polio shot was administered to a group of children in New York City, who were among the first to receive the vaccine.

This vaccine had been created to be the perfect vaccination against polio, and it was designed specifically for children who were not yet vaccinated.

The polio vaccine wasn’t the first vaccine to be developed in the USA.

In 1900, the World Health Organization (WHO) and the American Medical Association (AMA) both approved the use of the smallpox vaccine.

However, polio wasn’t as well known at the time.

Many believed the polio virus was harmless and the US didn’t need a vaccine.

The American Medical Society (AMA), which had been working on polio vaccine since 1903, thought the vaccine would only make the disease worse.

It was later determined that the vaccine actually made the disease more deadly.

As polio was becoming more and more prevalent in the U.S., many people were also being infected with the disease, and the vaccination campaign had to be scaled back to allow for the spread.

The next polio vaccine in the country In 1921, more than a year after the vaccination, President Harry Truman signed the Vaccine Act into law.

This law called for a three-year trial of the polio vaccines for US citizens in a bid to get people to get vaccinated.

In order to be eligible for the polio vaccination, people needed to have been born in the year 1920, or at least have had one year of immunity.

The vaccine would also have to be manufactured in the first five years of its development and distributed to US citizens at least once every six months.

In 1922, the American Society of Pediatrics (ASP) recommended the polio shot be given to children who had a history of colds and flu, or who had been vaccinated against it in the previous two years.

The ASP also suggested giving the vaccine to children younger than seven years old to make sure they were vaccinated.

However a small number of doctors were against this approach, and in 1923 the AMA issued a policy statement calling on the federal government to stop the polio program.

The AMA also said the vaccine could be given only to children at risk for polio, to reduce the number of polio cases and to limit the spread to the youngest children.

The following year, the AMA was not the only group against the polio campaign.

The New York Times published an article by a pediatrician who opposed the polio vaccinations and called for the use in children of vaccines made by Bayer, Merck, and DuPont.

He said that the vaccines made in these companies would have to prove that they were safe and effective before being given to infants.

In 1924, the polio pandemic had taken a heavy toll on the US economy.

The economy had lost millions of jobs and millions of dollars in revenue.

In 1926, Congress passed the Agricultural Adjustment Act, which created a program to help farmers pay back their debts to the government.

The Agricultural Adjustments Act was intended to help small businesses and farms survive during a recession, and was supposed to help with the cost of food, gasoline, and other items that were being imported from other countries.

The law also gave the government the authority to impose a 10% tax on imported goods, as well as to increase tariffs on certain imports.

The tariffs were imposed on many imports, and this led to a dramatic drop in the amount of food and other goods that were exported.

The trade deficit rose significantly, as imports from China, the second-largest economy in the world, rose from about $600 million in 1921 to more than $3.5 billion in
