Polio Vaccines

Before the creation of the polio vaccine, 3,145 people including 1,873 children died of polio in the United States. and that was in 1952 alone. In 1955, the first polio vaccine was created by Jonas Salk which was taken orallySince 1979, not a single case of polio has been reported in the US.

Poliomyelitis, more commonly known as Polio, is a disease caused by the poliovirus. In about 0.5% of polio cases can result in the muscle becoming so weak that you have the inability to move. This weakness can occur over a few hour to a few days. The virus will enter into the mouth and effect the first cells it comes in contact with. In cases where the infected become paralyzed, the virus spread along specific nerve fiber pathways , preferentially replicating and destroying the motor neurons within the spinal cord, motor cortex, or brain stem.

There are two types of polio vaccines. The injected vaccine contains a form of inactivated poliovirus. The oral vaccine contains a weakened form of the virus through the mouth. These two vaccines have almost eradicated the virus going from an approximately 350,000 cases world wide in 1988 to 74 in 2015

The polio vaccine is not live. Since the virus is inactivated, it is a dead vaccine.
