Polio, more specifically poliomyelitis, is an infection caused by the poliovirus. This enterovirus is asymptomatic or causes minor cold like symptoms, in over 95% of those infected. Most people who get infected with poliovirus, about 72 out of 100, will not have any visible symptoms. About 1 out of 4 people with poliovirus infection will have mild symptoms that may include:

•Sore throat
•Stomach pain
These symptoms usually last 2 to 5 days then go away on their own.
Fewer than 1% of polio infections in children result in paralysis and it is generally resolved when fever subsides and regular body temperature is resumed.

Of the Less Than 1% of Polio Infections In Which a Child Experiences Paralysis, Only 2-5% Are Fatal

With a 0.02-0.05% fatality rate, not of polio infection, but of paralytic polio infection specifically, the outcomes are not nearly as grim as conveyed by the public health officials. Looking at the data alleviates much of the unnecessary fear over a mostly mild, if even symptomatic, infection.

The first polio vaccine, an Inactivated Polio Vaccine (IPV), was created by Jonas Salk in 1953, followed shortly after by the live attenuated polio vaccine (OPV) created by Albert Sabin in 1956. Salk’s IPV was grown on monkey kidney cells (Vero Cells) and inactivated with formalin.

After a failure to inactivate the vaccine virus at Cutter Laboratories in 1955, over 40,000 kids were infected with polio and hundreds experienced vaccine induced paralysis. As a result of this failure 10 children were killed. In addition to this occurence known as The Cutter Incident, the monkey kidney cells, or Vero cells, used to grow the IPV (and still in use today) have been shown to be contaminated with Simian Virus-40 (SV-40), a cancer causing virus only previously found in primates. Millions of American citizens have been injected with vaccines contaminated with this virus. CDC admits to its existence, but dismisses any link to oncogensis in humans, despite the scientific consensus: 

Widespread vaccination against polio in the United States began in the 1950s and 1979 marked the last case of wild-type poliovirus infection in the US.  Since then, all cases of polio infection have been traced back to strains from the polio vaccine(s). But it doesn’t end there, the history and truth about polio is a bit more complex. There are many factors that play a role in the incidence of this infection.
As advances are made in the medical field, scientific understandings deepen, diagnostic testing improves, and more accurate identification of infectious pathogens is achieved. This is extremely evident in the case of polio diagnosis. Historically, many differential diagnosis were overlooked for the more “popular” polio label. Polio became a catch all diagnosis for any acute flaccid paralysis or similar symptoms, inlcuding paralysis from exposure to poison.

Polio or Poisoning?

During the days of peak polio diagnosis the insectiside Dichlorodiphenyltrichloroethane, or DDT, was introduced and was being sprayed on orchards and farms, swimming pools full of children, mixed in wallpaper paste, and slathered any and everywhere the industry could convince people to put it. The effects of DDT poisoning causes similar symptoms as polio, including paralysis. The science on the dangers of DDT use is now well documented and it’s use was banned in the US in the 70’s. Here are some resources where you can explore more about DDT:
Along with the phasing out of poisonous DDT, the medical and scientific communities made discoveries and advanced understanding of infectious pathogens and their resulting symptomology. With updated focus on accurately diagnosing polio-like illnesses, such as other enteroviruses, acute flaccid paralysis, transverse myelitis, myopathies and dystrophies, true polio diagnosis now requires confirmation with lab testing, to avoid misdiagnosis.

Polio Overdiagnosis Results in False Sense of Infection Decline as Better Diagnostic Criteria is Established

Today in the US we use only the Inactivated Polio Vaccine (IPV), but the oral polio vaccine is still used in other countries. CDC recommends children get four doses of IPV at 2 and 4 months, between 6 and 18 months, and again between 4 and 6 years old. There are several combination vaccines on the market in the US that contain polio vaccine components, however for simplification purposes we will be looking at only the singular polio vaccine, IPOL.

IPOL, similar to Jonas Salk’s IPV, uses poliovirus grown in Vero Cells. In addition to the previously discussed issues with these cells, an FDA report prepared by Rebecca Sheets, PhD, states, “Vero cells are sensitive to infection with SV-40, SV-5, measles, arboviruses, reoviruses, rubella, simian adenoviruses, polioviruses, influenza viruses, parainfluenza viruses, respiratory syncytial viruses, vaccinia, and others.“.

Along with the Vero Cells, bovine calf serum, formaldehyde, and various antibiotics are used in the manufacturing process. It’s package insert lists the following as documented adverse events following vaccination:
Blood and the lymphatic system disorders
General disorders/Administration site conditions
Agitation, injection site reaction including injection site rash and mass, fever, irritability, tiredness, persistent/inconsolable crying 
Digestive disorders
anorexia, vomitting
Immune System Disorders
type I hypersensitivity including allergic reaction, anaphylactic reaction, and anaphylactic shock 
Musculoskeletal and connective tissue disorders
arthralgia, myalgia
Nervous system disorders 
convulsion, febrile convulsion, headache, parasthesia, and somnolence, Guillain-Barre Syndrome 
Skin and subcutaneous disorders
rash, urticaria

Vaccines Not Studied For Long-term Carcinogenic Effects or Fertility Impairment

And as with all vaccines, long-term studies to determine the carcinogenic/mutagenic potential or impairment of fertility from the IPOL vaccine have not been done, though scientific literature on the individual compounds in vaccines and their oncogenic tendencies is vast.

The history of the poliovirus is slightly more complicated than the vaccine industry’s narrative of eradication via vaccine, but an investigation into the facts reveals a much less terrifying situation than the industry would have us believe. Use your discernment and analyze the data yourself to make an informed decision.
