POLIO VACCINE
The polio vaccine treated patients with the polio disease, which was one of the most prominent disease in the 20th century

The polio virus contains an RNA genome that is enclosed in a protein shell

- Polio is spread by the fecal-oral route; the virus is transmitted from the stool of an infected person to the mouth of another person from contaminated hands or objects such as eating utensils
- Some cases might spread directly by an oral to oral route
- Some cases might spread directly by an oral to oral route
Symptoms of the disease include...
1%–2% of infected individuals: develop temporary stiffness of the neck, back, and/or legs
Less than 1% of infected individuals: flaccid paralysis; permanent weakness or paralysis of legs, arms, or both
- Symptoms for this disease are very minor but a few symptoms could include…

2 types of vaccines that fight against polio:
Inactivated poliovirus vaccine (IPV)
- Consists of killed poliovirus strains- Given as an injection in the leg or arm, depending on age
- Produces antibodies in the blood, and in the event of an infection, the antibodies prevent the spread of the virus to the central nervous system and prevent paralysis
Oral poliovirus vaccine (OPV)
- OPVs are administered orally and do not require health professionals or sterile needle syringes, which make it easy to administer
- The weakened poliovirus contained in OPV are able to replicate in the intestine, but is about 10,000 times less able to enter the central nervous system than the wild virus, which allows individuals to build an immune response against the virus

The picture on the left shows the oral poliovirus vaccine, which does not require any type of injection but treats patients with medicine (usually given to younger kids). The picture on the right is an example of inactivated poliovirus vaccine, which as seen in the picture is given through shot injections.

Effect on Life Expectancy
- The Polio virus aused many to face a slow death from paralysis, especially if it occurred in the lungs
- The invention of the vaccine eliminated these viruses, leading to less deaths from polio, and allowed individuals to live a more successful, healthy, longer life
