Polio is an enterovirus, and it's not the only enterovirus capable of causing paralysis. Enteroviruses are fairly common, most people who become infected have no or few symptoms. If symptoms develop, they are like a cold or mild flu. One enterovirus that has been in the news lately is called "EV-D68" which can cause polio-like paralysis they call "acute flaccid myelitis (AFM)". CDC acknowledges this.
What turns an asymptomatic or low-symptom harmless enterovirus infection into an ER visit and hospitalization? In 1995, researchers figured out that with the polio enterovirus, it was intramuscular injections within 30 days of being given a live polio vaccine. They were studying cases of "provocation" poliomyelitis following receipt of live polio vaccine.
Like other enteroviruses, 95% of polio infections are asymptomatic or very mild. Polio only very rarely leads to paralysis. Researchers in 1998 stated: "Muscle injury due to injection of vaccines or therapeutic agents is common in medical practice. It has been observed that, if concurrent with PV infection, such injury may increase the risk of neurological complications."
PV is polio virus, but as noted above, other commonly circulated enteroviruses can lead to paralysis.
With children today being given so many intramuscular injections so often throughout childhood, odds are a seemingly well child will actually be infected with (and successfully fighting) an enterovirus when given a round of vaccines.
And with the ACIP dangerously telling pediatricians it's OK to vaccinate mildly ill children, those who have earaches or are on antibiotics, the odds increase that a child infected with an enterovirus will be given a round of vaccines, possibly leading to AFM.
How can this be prevented?
This is but one example of why the entire vaccine industry and policies need to be reformed. First Do No Harm.
Mechanism of Injury-Provoked Poliomyelitis

Skeletal muscle injury is known to predispose its sufferers to neurological complications of concurrent poliovirus infections. This phenomenon, labeled “provocation poliomyelitis,” continues to cause numerous cases of childhood paralysis due to the administration of unnecessary injections to children in areas where poliovirus is endemic. Recently, it has been reported that intramuscular injections may also increase the likelihood of vaccine-associated paralytic poliomyelitis in recipients of live attenuated poliovirus vaccines. We have studied this important risk factor for paralytic polio in an animal system for poliomyelitis and have determined the pathogenic mechanism linking intramuscular injections and provocation poliomyelitis. Skeletal muscle injury induces retrograde axonal transport of poliovirus and thereby facilitates viral invasion of the central nervous system and the progression of spinal cord damage. The pathogenic mechanism of provocation poliomyelitis may differ from that of polio acquired in the absence of predisposing factors.
