When did the first polio vaccine become available?

The first polio vaccination shot was made available to all American children in December 1918.

It was also the first shot in the U.S. to be administered to children in areas of the country where polio was endemic.

In the years that followed, the number of U.N. countries that had successfully inoculated children against the disease dropped dramatically.

And in 1947, the U and U.K. were able to inoculate nearly all children in their own countries, thanks to the work of British scientist and virologist Richard Feynman.

Feynmans work, in collaboration with other scientists and engineers, led to the development of the polio vaccine and the first successful human vaccine.

The U.A.E. and the U (the U.M.A., the U of S., the M.A.) have since become polio-free countries.

The first shots to be distributed in the United States were made available in March 1946.

It wasn’t until the summer of 1947 that the U S. received the first vaccine in a vaccine made in the Minsk area of the Soviet Union.

Today, the first vaccines in the world are available for free.

What is polio?

Polio is a disease that affects the nervous system.

It affects the central nervous system and can lead to paralysis or death.

In many countries, including the U, the disease is more commonly known as poliomyelitis.

This disease affects approximately one in every 6,000 people in the country.

The symptoms of poliococcal disease include fever, chills, headache, fatigue, and shortness of breath.

Symptoms usually last for about a week, although it can sometimes be more than a week.

There are no known vaccines available to treat this disease, but some types of drugs can be used to treat it.

The vaccine is a mixture of a virus called a vaccine virus and a protein called a preservative called a adjuvant.

There is also a form of vaccine called a rotavirus vaccine, which is the same as the vaccine, but is made of different materials and contains less vaccine.

Because of the long incubation period, a vaccine cannot be administered immediately, and the vaccine must be administered in the form of a small droplet.

The shot contains a tiny amount of the virus and contains the preservative.

The shots are then put into the arm of a healthy child.

The initial dose is administered to the child on the upper arm and then slowly pushed into the back of the child.

This method of inoculation is called a subcutaneous injection.

The dose is then given on the same day as the injection and is administered for up to 12 hours.

The child must be able to walk or stand, but no one must be in any pain or discomfort.

In addition to the vaccine shot, the child is also given a dose of an antibiotic called a polysaccharide, which helps protect the body from infection.

The polio vaccine is also administered by mouth.

The vaccination is usually given by a nurse in the hospital’s emergency department.

It is given under the supervision of a doctor, who also administers the vaccine.

Once the child has been vaccinated, the vaccine is taken to a lab and the immune system is cleared.

In some countries, the dose is diluted and given to the parents to make sure that no new cases develop.

How long does it take for a vaccine to be effective?

The time it takes for a shot to become effective is called the “time to protection.”

In the U., the average age of the person who gets the shot is between the ages of 12 and 25 years.

In most countries, that age range is between 12 and 19 years.

This means that in the next 12 to 24 months, about one in three people will get the vaccine and get the disease.

The chance of getting the disease decreases with age.

In countries that use a vaccine in the first week of the disease, the chance of developing the disease increases, so that by the time a child gets vaccinated, he or she is nearly 100 percent protected.

But the average vaccine in countries that do not use the vaccine as quickly as the U has a much higher chance of not being effective.

Some countries have a longer incubation time, which means that they have a higher chance that a vaccine will be effective before it has even been administered.

It takes at least six months for a child in the average U. S. country to get the first dose of a vaccine.

In Canada, the average time to protection is 14 months.

In China, the vaccination rate is 15 to 20 percent, in India it is up to 40 percent, and in the Philippines it is 60 percent.

In Japan, the rate is 20 percent.

The average time for a country that has a vaccine is around seven months, but in countries without a vaccine, the incubation may be longer.

If the vaccination is not effective, the person is
